    lowest entry cost GPS for Strava

    I'm interested in picking up a GPS for the sole purpose of playing around on Strava - local competition. I've never shopped around for a GPS before and it appears that the options are ridiculously numerous. I don't need any fancy features. Basically i want to be able to strap something to my arm or stem or throw it in my camelback then ride. When i get home i'd plug the device into my pc and see how i did vs others.

    What do you suggest?

    Thanks,
    head

    Costco member? They have a Garmin 405 w/premium HR monitor for $159. ::link::

    You can use a handlebar mount ($15) or wear it on your wrist.

    I've read that Strava is catering to the cell phone market & no longer uses the barometric elevation readings from GPS's. This makes your ride climbed & descents (usually) shorter. If this doesn't bother you then any cheap GPS or phone with GPS will work.

    You can get a Garmin Edge 200 for around $150.

    blackberry curve and GPSLogger. Don't even need a SIM card in the device. GPSLogger is Free. (Free as in freedom, no activity harvesting) GPS Precision is good. I pass the files from the phone to the laptop via bluetooth and upload to strava.

    *Every* smartphone platform has a number of GPS apps. If you already have a mobile phone capable of running third-party applications you have to find one that writes to a file type supported by strava.

    I don't use Starva but I read that on these boards. You are more then welcome to conduct your own search.

    I run an iPhone 4 using MotionX-GPS & upload to Geoladders or Garmin Connect.

    There was a discussion last week about a change in the method of speed/distance calculation to work better with mobile phones (which Strava later decided not to do) but I saw nothing about elevation.

    Wow... this is cool. I have my wifes old blackberry bold no longer has sim card. I use it for streaming pandora off our house wi-fi and now it looks like I can re-purpose to track my rides on GPS.

    Does the phone need light of sight to get a signal or if it is in camelbak will it still get a signal?

    It worked.. I took my old blackberry bold 9700 and despite not having sim card any longer I downloaded GPS Logger II via home wi-fi. I then turned it on and did a ride this weekend. I put it in my camelbak and did a ride. It recored the entire trip. I did not get any maps while on the trail as the phone had not data connection, but it did track GPS data like position speed and elevation.

    Just what I needed for the right price $0. So left over blackberry with wi-fi =FREE, GPS Logger II app = FREE. Being able to track your ride for FREE = COOL. I love to know where I have been.

    Has anyone had any experience with simple dataloggers?

    Amazon.com: i-gotU GT-120 Travel Blog Master (USB GPS, Data Logger, SiRF III Chipset) (Bumper Case, Data Cable and Software Included) (GT-120): GPS & Navigation
    http://www.amazon.com/Holux-M-1000C-.../dp/B001QRCZ7C
    http://www.amazon.com/M-241-Bluetoot.../dp/B0011XV19O

    There are several others which look interesting as well.

    $60 for a GPS - no bike computer functions but if you want the cheapest entry to GPS use, it's hard to beat $60.

    Well, obviously if you have an old phone with GPS, that beats that, but the phone cost well more than that when it was new.

    I picked up a Canmore 730 GT-FL(S) off ebay for $40 to experiment with (I also own a705) and I have to say it does the trick. Low cost, compact, and fairly simple to operate and integrate. I would recommend it to anyone looking for a low cost gps device.

    Nice, I missed that one completely, thanks! $5 cheaper than the Holux M-1000C I picked up. Looking forward to comparing it to my android phone and the wife's Edge 500.

    I guess if I were to compare the two it looks like the Canmore is quite a bit smaller. It's about the size of a fat USB flash drive and weighs practically nothing. It has a built in battery, the holux seems to also require batteries? I'm guessing the holux wins in features as the canmore has practically none. Just turn it on and it records, press the button to store a waypoint, turn it off.

    The Holux is very similar in features, or lack thereof. It's very simple. It does have a battery from a Nokia cell phone, which would probably give it more recording time before it needs to be charged just simply because it's bigger. The chipset in the Holux is supposed to be really good, as well. Don't know how long the Canmore lasts, but if it's at least a couple hours, I'd say it's a better choice. Can you set the logging interval down to 1 second on the Canmore? I would think -- especially for MTB -- that the smaller logging interval is kinda necessary, especially on really twisty trails. If you only sample every 5 seconds, a really twisty trail might wind up looking basically straight.

    According to the docs the battery is supposed to last 18 hours. I did update the config to log every 1 second. It stores 256k points whatever that works out to a 1PPS.

    Wow, if that thing turns out to be comparable in accuracy to the Holux, it's a way better buy. Smaller, simpler, 1 second intervals, and good battery life. I may have to get one (WTH, it's cheap) and compare the two. Thanks!

    edit -- Bought! Picked up one for $38 with free shipping from ebay. I'll soon be able to compare the Canmore, the Holux, a Garmin Edge 500 (maybe an 800 if I can con one of my buddies into lending it) and Android phones. (Motorola Cliq and Galaxy Nexus)

    Should be interesting, if nothing else!

    Any chance of adding any handhelds to the mix? That could be an interesting test.

    Sure thing, send me what you've got!

    I haven't had a handheld since my first GPS, a Garmin GPS III. I know a guy with a handheld he uses for Geocaching, but I don't see him very often.

    Otherwise, I'd love to incorporate those.

    I have Strava segments to compete for...I don't plan on sending my Oregon.

    The Oregon will probably be similar to the Edge 800 if you can get that one into the test.

    I was thinking more about one of the new eTrexes, maybe a Delorme. But still, if you did such a test in a pretty systematic way with calibrated distances under different circumstances, that could be good stuff. I'd even offer to let you write it up as a guest post on my site if it was good.

    I went out for a ride tonight with three units:

    1) Garmin Edge 500 on the stem in the normal configuration
    2) Holux M-1000C attached to the top of my helmet with velcro - light enough to not notice it and best view of the sky. Plus, once it's on, nothing else to do with it, so don't need it accessible.
    3) Motorola Cliq running MyTracks in a ziploc in my center rear jersey pocket.

    This was a road ride, so I rode through a small office area to get a better idea of the GPS accuracy.

    In terms of ease of uploading, the phone wins, hands down, going away. As soon as I get home, it picks up my wifi (no data service, it's an old phone which was upgraded) and I can upload the GPX to dropbox (dropsync app handles that automatically) or email it directly to Strava. (The Strava app is sketchy on the older hardware, MyTracks is dead relliable.) No need to plug it in for anything beyond charging. The Garmin comes in next with the browser plugin and removable media functionality, but you still have to bring it in and hook it up to the computer. The Holux comes in DFL because it has to be connected, like the Garmin, but then you have to use their software to get the data off, THEN export it to a GPX. Their software is pretty ugly, and requires you to enter a product key. Since the software is useless without the datalogger itself, I think having to enter a product key that's longer than the one on a Windows installation is pretty stupid. Nobody's going to pirate this turd.

    In terms of accuracy, however, the Holux wins it going away. First thing I did before I went on the ride was to change the logging interval from the default of 5 seconds to the minimum of 1 second. This was really, really apparent in the resulting tracks. Riding through the office complex, the Holux track had nice, smooth, curves. Really quite impressive. The Garmin was in the right general area, but I think it's got a default of 5 second intervals, and you can tell as the same corners are sequences of large straight lines. The old phone, I've tweaked MyTracks to the shortest recording duration, but I guess due to the lower quality GPS unit in that, it looks like I was chugging coffee with energy shot chasers. The tracks are accurate-ish, but jagged.

    I didn't bother using my Galaxy Nexus because that has some known GPS issues (so I've heard) and it's a bit of a battery killer.

    (I can upload screen shots comparing the tracks, but wanted to get this out)

    I've been uploading to Strava from the old phone, so did that after the ride. I didn't upload the other two so I didn't confuse things. Might upload them and make them private (or flag them) so they don't show up as multiple rides. It'll be interesting to see how the coverage differences affect segment times.

    So if you don't need to ride with a display, and don't need to follow the directions, and can deal with a little annoyance with the uploads, the Holux wins, especially considering it's $60 vs. $250 for the Garmin. *especially* considering the finer 1sec sample time for MTB use. In terms of ease of use of the unit, there's an on-off switch. Once it gets a GPS signal (indicated with LEDs) it starts recording. Nothing else to do. Done with the ride? Shut it off. That's it.

    I know there is some third party software which should work with the Holux, I'll be curious to see if I can do something a bit more automated.

    Really, really interested to get the Canmore unit now. If it's as accurate as the Holux and the battery life is as good as they advertise, it's simply unbeatable at sub-$40 shipped.

    Not doubting the value for the $$$ reasoning, but... why set the Holux to 1-second recording and not do the same with the Edge 500?

    I thought one of the neatest features of the Holux was the Bluetooth connectivity - I believe you should be able to use a Bluetooth GPS app on your Galaxy Nexus to acquire the data from your Holux instead of its internal GPS. That should make the post-processing easier, too, no? I just started reading about this, so I'd be interested if you can try that combo.

    Is it possible? I've looked and haven't found where that can be set. I thought that was the big selling point of the 800 over the 500. Tell me how and I'll give it a go.

    Yeah, in theory it can be done. I've seen some things about it, you basically have to disable the internal GPS and then pair it and then enable mock locations under debugging. Something like that, I don't remember the exact steps. Can try that, time permitting.

    when was the last time you updated your firmware? it was included in an update some time ago. advantage of the edge 800 over the 500 is mostly mapping capability (and all the associated things you can do with maps).

    Hadn't even looked at updating the firmware yet. Just did a quick search and found it, I'll have to check and see what I was running and update tonight. Good deal, was unaware of that, obviously I hadn't really investigated too deeply. Considering the Edge is the wife's, and she's almost entirely MTB, this will be a very good fix to make. Thanks!

    The 1-second recording vs. smart recording is buried in the bike settings menu, and is independently selectable for each bike, meaning you can enable it for accurate tracking on your mountain bike and leave it off to avoid 20-megabyte *FIT files at the end of an all-day road ride.

    Some people upgrading with *.fit files left in the memory are experiencing issues ranging from inability to upload, to completely bricking the unit.
    (Bricking the wife's Garmin would be a bad scene, I suspect.)

    Well, I was at 2.80 so I had the 1 second recording, my bad. Didn't look under the bike config. Makes sense, but since she's just got the one, won't change too much.

    (Bricking the wife's Garmin would be a bad scene, I suspect.)
    Yeah, that might not be great -- but at least she's still got the Strava app on her phone, which is easier and faster anyway. Either way, I followed that advice and am upgraded to 3.0.

    Next time I get out on the bike I'll give it another go and see how we do. I'm expecting the Garmin will now be on level footing with the Holux. Will probably wait until the Canmore comes in, that way I can have even more datapoints.

    In other news, I was able to pair the Holux with the Galaxy Nexus, turned off the internal GPS and enabled mock locations. Maps complained but as I walked around the block, it showed me right where I was supposed to be. Both MyTracks and Strava, however, not so happy. Even though MyTracks showed my icon moving on the map, it listed my speed and distance as zero. It had a message on the screen about how I needed to enable the GPS for it to work. Strava was the same deal -- warning messages about no GPS, and no recording.

    Edit: Forgot a step... need the app "Bluetooth GPS": https://play.google.com/store/apps/d....android.btgps

    Quick update. Accidentally left the Holux in the car yesterday, sitting on the dash and running all day. Was still running when I got back 10 hours later. Not like I should be surprised, the rated battery life is way past that.

    Got the Canmore yesterday, started playing around with that. Hoping to get out for a ride this weekend with heavy GPS coverage. Figuring:

    Canmore datalogger
    Holux logging and paired to Galaxy Nexus
    Motorola Cliq running internal GPS
    Garmin Edge 500 (now adjusted to 1 second intervals)

    This will be a MTB ride with good tree cover. Probably velcro both of the dataloggers to the helmet.

    Before you head out for the test be sure to use the GPSViewer.exe program to configure the Canmore to save the datalog (I know, silly right?) and to store one point per second. The default is to not store anything 5 times per second. Probably so as to not record the exact coordinates of the factory it was made in or every place it was ever powered on before you bought it or something like that..

    Went out for a ride, forgot some of the stuff, but set up the Canmore and the Holux. Had both velcro'd to the helmet, the Holux on top in the back and the Canmore just behind it. Amusingly, the Canmore fit right between the vents in the back of my helmet, and almost didn't need any velcro to hold it in place. Even with the two of them up there, I completely forgot that they were there, the weight is negligible, and this is a light helmet.



    Still have to write up comparisons and post links to tracks and all that crap, but here are my initial thoughts:

    * The Canmore is definitely the winner for best price. $40 is hard to beat.

    * The Holux seems to be more accurate -- actually, scratch that, it's more _precise_. On out-and-back rides on the same track, the Holux comes very close to completely overlaying the tracks. The Canmore, not so much. In other tests, (tracking the dog when we went out for a walk, had the unit on his harness) the Canmore's resolution seems worse than my Galaxy Nexus, I mean remarkably bad, (jagged mess with what looks like very infrequent logging, despite being configured for 1 second intervals) and it had a full view of the sky. So far, the Holux has been far more consistent with good readings.

    * The winner of the price/accuracy/ease-of-use competition, and the way I will probably be going from here on is the Holux paired to an android phone via Bluetooth and running the Strava app. With this, you get the accuracy of the Holux (mounted up on the helmet for the best sky view) and the ease of upload of the Strava app. Plus, if the Strava app has any issues, the Holux is still logging, so you've got a backup of the ride.

    (I really haven't done any testing to see how the phone with internal GPS fares vs. the phone with paired bluetooth in terms of battery performance. Paired, on a three hour ride, the phone dropped from about 90% to just under 50%, but the Galaxy Nexus is a battery killer to begin with.)

    * The software looks exactly the same between the two, just branded slightly different, with the same ridiculous 28-character product key, and it's just as bad for both. Better yet, the Holux software won't talk to the Canmore, and vise-versa. Plus, since the USB connection is a serial port, not removable storage, you have to figure out which port each time (it moves around, never just COM5 or whatever) and then connect to it. The auto-scan function doesn't work for crap. (this is all on Windows 7) It's not horribly difficult, but it's a pain in the ass. Still haven't done too much with looking at third party software.

    Although the Holux is $20 more, the bluetooth option, as well as the more consistent logging, makes it my choice for budget GPS, especially if you've got an android phone. (no idea if it works with iPhone or anything else, that's outside my GAF)

    None of these options give you any display. That's fine for me, but if you want to see how far you've gone while you're going, then you either need a phone and a handlebar mount, or just get a Garmin.

    I'm curious (but not enough to bother looking it up) if the Edge 200 shares the 1 second logging option with the 500 -- and if it does, the extra $90 to get a display, the better precision, and the hugely easier uploads would be WELL worth it.

    Speaking of the Edge 500, my wife ran hers with the logging set to 1 second, and comparing the maps, the Edge is almost as precise as the Holux. I'd say they'd be right on the money if the Edge had the same view of the sky as the Holux.

Probably so as to not record the exact coordinates of the factory it was made in or every place it was ever powered on before you bought it or something like that..
    Yep, first thing I did was configure it. Thought it a bit odd for a datalogger that defaults to not logging. Did see a short log from what looked to be the factory, that was kinda cool.

    Comparing the Holux and the Canmore on an out-and-back segment:

    Both are perfectly usable, but the Holux exhibits better precision.

    A quad helix antenna is more forgiving of orientation. Do another test and either swap the receivers or figure out a way to orient the two the same way.

    I wondered about that. But, when I had the Canmore on the dog's harness, it was on top, facing the sky with the button side up. The accuracy was piss-poor, to the point that the Galaxy Nexus logs looked good in comparison. Maybe that's not the "up" side. Still, it ships with a lanyard, so I'm guessing if you use it the way it's shipped, it would wind up in a vertical orientation, just the other end up.

    Still, I'll give it a try with the Canmore up top.

    Edit: Here's the log of our walk around, showing how accurate the Canmore can be when it's facing upwards. I am fairly certain our dog neither flew nor walked across the roof of any of the houses. It was a clear, sunny day.

    crap, that looks awful. I'd play with the orientation to see if one way or another works better. Maybe my assumption about the antenna orientation is wrong.

    Good info, cmh. I was just wondering which model Holux device you tested.

    Also, there's a lot of TomTom MK-II Bluetooth receivers for sale on the web. They're cheap and have an internal quad helix antenna.

    Review posted on Amazon.

    Most of this won't be news to you if you've been following this thread, but I've written up a review for the Holux:

    Hope this information is useful. Please let me know if I missed something!

    My Holux (m-1000c) data looks much blockier, less smooth than the above screens. The data seems good for mileage, altitude and time. I haven't use much just wondering if it's a setting. I already set the time to 1 second, my son uses an iphone he said is set to 3 sec and his data looks much smoother. I wasn't sure about the setting for degrees, minutes, seconds or just degrees, I had it to degrees. I will switch to deg, min, sec setting but not sure if this will help. I will directly compare to the iphone this weekend.

    Wow, Mark, I'm surprised. You're saying that the accuracy that you're seeing from your M-1000C is lower than an iPhone? That's completely the opposite of what I'm seeing. Where do you have it mounted when you ride?

    Degrees/minutes/seconds vs. Degrees is just a display thing. The unit is saving the information in degrees, but you can convert it so it'll display in degrees/minutes/seconds, which you might see on some maps.

    I thought so on the degrees thing and the accuracy. My Holux of 1 sec vs. his iphone 3 secs. I put it in my backpack, do you think it is having trouble receiving the signal? His iphone is in his backpack also.

    If it's near the outside of the backpack so that it gets a good view of the sky, it should be fine, but if you can try mounting it on top of your helmet, give that a go. Still, in a backpack, as long as it's near the outside (not buried in stuff) then it should work just fine.

    I wouldn't go that far. It depends a lot on the hardware, receiver sensitivity, and that sort of thing. A layer of fabric between the device and the sky can make a difference. Not to mention if it's in the pack, it's subject to being jostled around so the antenna may wind up pointing down or it might eventually get buried under stuff or you might have something else in the pack that would interfere. two GPS receivers next to each other can interfere. need I remind anyone of the iphone 4 reception problems if you gripped it just right? that sort of stuff happens.

    stuck to the top of the helmet is probably best. lashed to the top exterior of the pack would probably be my #2 spot for a BT GPS puck. inside the pack would be WAY down the list.

    It's works very good now, operator error. I was exporting the tracks then typing Y which reduces the resolution and size of the file. Very smooth looking now. Thanks cmh for all the research, good product.

    This is in interesting thread.

    How did the cheap gps loggers last?
    For how many hours can you log with 1s sample interval before they run out of memory?
    Which Canmore device did you test? I saw their new 730 has a sirf 4 chip which is supposed to be more accurated.
    Ride more!

    Still using my Holux M-1000C. Still works like a champ. Sometimes I pair it with the phone via Bluetooth and run an app, but mostly I just switch it on, ride, switch it off, then download when I get home. One day it seemed like it was acting up, so I pulled the battery and left it for an hour or so. Came back and it's worked fine since then. Remember that this thing is velcro'd to the top of my helmet and as such has taken the brunt many times when I don't duck enough for low trees. There has been more than one ride when I get done and have some bits of flora caught underneath it.

    For how many hours can you log with 1s sample interval before they run out of memory?
    First time I tested it I left it on the dash of my car all day long. It logged all day - say around 7 in the morning to about 5:30 at night. I didn't check to see how much free memory was left, though.

    Which Canmore device did you test? I saw their new 730 has a sirf 4 chip which is supposed to be more accurated.
    Well, the upside is it would be hard for it to be less accurate than the one I have. I don't remember the exact model, it was the (bunch of letters) 730 (more letters). I don't even know - or care - where it is.

    I have used the Holux M-1000C since Sept. 2012 and it works great. I have never had the battery die or had it lose the gps signal. I just turn on see the gps light flash and put in my backpack then turn off when finished mt ride. I upload to strava later and delete from the Holux at that time. I charge the unit with my laptop while surfing the web. Very simple.
