    Cycle computer then to a droid and now to gps

    Hi guys, I started by looking for a cycle computer with HR monitor and a big screen, wanted temperature and the other regular stuff. I decided in a CatEye V3 Wireless Computer with Cadence & Heart Rate.

    Started seen pics and the display doesn't look too big. Saw a polar model and it looks huge like I wanted but they are around $250.

    Then I started looking at the small garmin models and they have big screens but they are pricy, at the same time I was thinking about the use of my droid razr maxx and found that they aren't that accurate plus I know I might run out of battery by using the gps. and I would like to be able to make a call in case of an emergency.

    I stared looking at the edge 200 then 800 and 800 bundle.
    I like the 800 bundle because it has the HR and also the speed/cadence sensor. Correct me if I'm wrong, will I get much better results with the speed/cadence sensor than the actual gps, FYI this will be use on a MTB, (I'm talking about sharp turns).

    Will I get all the usual stuff from a cycle computer on an edge 800, like
    •Current Speed, Cadence, Heart Rate
    •Calorie Consumption
    •Countdown Distance
    •Lap Time, Distance, Average Speed, Number
    •Total Time, Clock & Date
    •Wireless measurement of speed, cadence and heart rate
    •4 heart rate zones
    •EL backlight
    •3 lines, 4 readouts
    •Programmable odometer
    •Auto or manual start/stop
    •Pace arrow speed & heart rate

    Would anyone recommend something better than the Garmin edge 800 with HR?

    Thanks in advance for any advice.

    the speed/cadence sensor will give you more accurate readouts on the bike itself. most websites ignore data from the speed sensor, however, and calculate your speed based on your gps positions. the speed/cad sensor does not update those gps positions.

    So, is true that for mtb I might have problems with accurate readings in turns on the trails?
    I was just playing with strava and it looks nice.

    Calories burned is worthless on any device. "Real-world data collected by the FAA show that some high-quality GPS SPS receivers currently provide better than 3 meter horizontal accuracy." Below is a spot I passed 8 times on a recent ride. The trail is perhaps 1 m wide there. Note the 5 m scale. Assuming I was in the middle of the trail the 800 accuracy is pretty good. Make sure you use one second recording.

    Are you sure about that 1 second recording? Knowing the speed of my rides, when I import and view tracks that I have laid down, the points often seem much closer than 1 second to me.

    To the OP, you did not mention navigation and you mentioned $250 was expensive, then you picked a navigating GPS bike computer. Seems like a lower end model would be good enough for you perhaps.
