    For the Trailbuilders

    An application for a clinometer to work on a "phone" whose brandname implies it has a small first person complex. Need a 5% climb? No problem ... let me whip out my "phone".

    Using a clino is the "right" way to build sustainable grades. Having one built into your phone would possibly be helpful. As presented in a JRA sort of way.

    Borneo's right. It works on an iPhone or iPad but anything w/ "i" in front of it bugs me to no end so I sort of inferred. Gee, Scotteric, sorry to have wasted your time. Saw a bit on it in the current Dirt Rag and thought someone might find it useful.

    Theolodite is a very useful, inexpensive clino/survey app for the iPhone / iPad. I used it quite a bit this winter figuring out the angles for the great spacecoaster at duthie. One thing that caused some confusion, it can measure grades in either degrees or percent. My understanding is that percent is the common unit of measure for trail building.

    Appears the App is named Theodolite. Cool looking app...might have to buy it.

    Cheers,

    I've used Theodolite, too. One of the other cool features is being able to take a photo with the reticule and the data (clino, position, etc.) overlaid. The only real downside over a traditional clino is trying to work with an iphone app in muddy, nasty, pouring-down-rain conditions. Which, of course, is when we usually build.

    FWIW, you can switch between degrees and percent, FM. There may have been some...er....barley-based interference when I was giving you numbers during some of the coaster scouting.

    Beyond being the "right" way, it's really the only way to effectively measure a trails's grade. Folks would be very surprised how far off you usually are when you just "eyeball" an angle. I know I was the first time I did it and then looked at it via a clino.

    Noteworthy, is you really need two people to best measure the angle of the dangle.

    Yep. Westra thought we were planning to make it 3.6x steeper

    Same reason good baristas reference scales, thermometers and timers.
    Science FTW!

    Yep, this what Froh and I did on the spacecoaster. Having two consistent readings validates the measurement.

    It was very helpful on the coaster, since if you get the angle on wood wrong, you can't fix it with a shovel!

    That phone app is really cool. Using a clino is a great educational tool on figuring out which side your dominant eye is.

    Left footed, right handed, left eye dominant, i'm all f'd up.

    Agree %100.
    Crashing a lot less since I started using a tire pressure gauge

    or seeLevel.

    A real clinometer is still going to be more accurate.

    The trouble with common sense is it is no longer common
