Customer Reviews

Used this on the HST

I used this as my main GPS navigation app on the High Sierra Trail and found it to be mostly accurate. I referenced the app mainly to anticipate water crossings and to chart progress (caution: sometimes demoralizing). I also carried the print version of the map, just in case of device failure (as happened on the JMT). One criticism would be that the custom pathway creation tool is difficult to draw with and not at all intuitive to use. I still can't get it to function 100% of the time, which is an annoyance despite the fact that I didn't "need" to anticipate the upcoming elevation gains that I couldn't just figure out from the topo. Still, I like elevation charts and it would have been a nice feature to reference if I had known how to use it. In any case, I hope many more of the Tom Harrison trail maps get published via this format because it (mostly) works and keeps it simple.

Pretty good map

Love this map. Detailed and accurate. One nice feature would be to see the topo map when completely zoomed out.

Also, bring on the Kings Canyon High Country map. I know Tom Harrison's got it. I've seen the paper version. Why are you holding out on us International Mapping Associates, Inc? Just call up Tom and say, "Yo Tom, can we make your Kings Canyon High Country map into an app?" I'm sure he would be very cooperative.
