Dave S.wrote a review of Suunto X9i GPS Watch on September 8, 2006
I've bought this watch and am VERY HAPPY with it. It has worked flawlessly and has been exceptionally accurate. I have used it while operating my car and it was perfect in distance over 103 miles. It can gauge speed and was dead on with the speedometer of my auto. I tracked back from 140 miles out and it was within .01 dead on accurate. You MUST read the manual from the CD. The watch is complicated and you must understand the functions to succeed with it. If you don't, you'll end up unhappy. Spend time reading and you'll find a new best friend.
