here for the instructions for the watch. We found the watch very accurate as we compared it to hikes we have done where we already knew the exact distance of the hike.
The cost of the watch is $65.00 retail. The only downside is the watch does not take into account elevation gain like a gps watch would. Thus if you are doing a hike with significant elevation gain the accuracy of the watch might suffer. However a gps watch will cost you at least twice the amount of money. Overall, we give the Timex Expedition Trail Mate Watch two thumbs up because it can still give you a great summary of any hike you are on and is also suitable normal every day wear.
