I was looking for a simple GPS for hiking and running (x-y location, speed, route tracking, predetermined routes to follow); I found a cool gadget that does all I wanted, plus some extras.
The GPS fix is usually under two minutes, and tracks mostly within 5m but sometimes within 15m of where I was when on a run, and sometimes does loose the signal completely in canyons and next to rock faces (as does most other GPS units). The track-back is fun to have, and works pretty good, as does the preloaded waypoint track feature. I have not been able to find an easy reference set of images that are prereferenced when loaded into the suunto software....so I end having to rereference all images and topos for preloading waypoints using google earth for reference points. Once the prewaypoints/the route are/is made, the loading up of these into the Suunto X10 is easy, as is following the route. Making kmz files for google earth is easy as there are tons of converters on line that will do this for you.
I really like the speed (usually pretty spot on, but does have some funky numbers at times), and on the move functions....but I wish there was a way to reset the starting time to 0. When beginning a run, I need to wait for the GPS to initiate and get a fix...this usually adds up to two minutes on any run I do (hence affectingthe overall speed average) and if I could reset this to 0 after an initial fix, it would function the way I need it.
The suunto software is a bit clunky to use, but it works...just keep pushing buttons, it is free after all.
A clearcoat finish on the rubber is peeling and I hope this is not going to be a problem with the 100m water proofing as I intend to go swimming/fishing/playing in and near the water with it when the season warms up.
Battery life is about 6-8 hours while using the GPS which is perfect for my use and I do intend to purchase the solar charger for longer than day trips planned this summer.
The GPS sits ok on my wrist, but I could see how some wrists might be too small.
Overal, it does what I want and gives a comparable location to the other gps units I have. The features are good and easy to manuver for viewing different things. Except for me not knowing if I can reset the average speed once the gps is on and fixed, I really like the suunto X10.
