Besides having a GPS feature that will save you in white conditions or help you chart and share your adventure with friends my favorite feature about this watch is the graphical view options you have for watching the barometer and getting a more accurate idea of what is happening with the pressure. This is crucial when you are waiting for a window and have to decide when to go big on a climb!

I was given this watch as a gift and was initially delighted. It is somewhat bulky, but pretty cool looking.

However.....

As a first-time Suunto user, I found the user's manual to be woefully lacking. I was also disappointed in the lack of Mac support.

As the owner of the X-Lander, I was familiar with Suunto products. I ordered the X10 with great anticipation, but was very disappointed.

I knew it had limitations -- poor battery life (making it unable to track for long backpacking trips unless a power source is avaialble) and no support for Mac OSX (or allowance for third party development apparently), but I could rationalize and work around them (or so I thought).

For something with such great promise, the unit requires too many button actions to get it operating. Even after those travails, which I figured would become faster with time, I found that it would lose GPS lock on a casual (ie, not fast) walk of a couple miles. This was confirmed a couple times. Upon returning each time I was greeted with the provided software, which is quite poor in design and operations. Yes, this goes well beyond a typical Mac vs. Windows bias.

While a nice try, and perhaps perfectly suited for GPS junkies, the X10 needs a lot of refinement.

I liked the features on the watch. Everything seems to be working fine. The battery lasts a long time on a single charge and the gps function seems to be very accurate. Only problem that I have is that the "protective ring" around the face of the watch which apparently was purely cosmetic has come off the watch. Now I have a copper ring exposed around the face of the watch. Everything still functions properly, guess I would have thought that if you paid $500 for a watch it would stay together.

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.

I had high (perhaps too high) expectations for the Suunto X10. It's design is sleek and menus not terribly difficult to navigate through after a few days of playing with it. *However* I was extremely dissatisfied with the amount of time required to capture a satellite signal. On runs in Atlanta, it took upwards of 15 minutes and then dropped the signal after running under an overpass. On a trip to the Peruvian Andes, the watch routinely took over 45 minutes to capture a signal and frequently failed to do so, and then kicking me into "manual" GPS mode. The altimeter seemed to work well, but I can't recommend the watch to anyway because of the difficulty with the GPS reception. Sadly, I will be returning the watch or waiting for the technology to improve.

I know this is about the X9 not the X10 but bear with me here. I am in the miltary and was lookin to reduce number of items and weight. So I thought combining watch with GPS was a good idea. I recieved the first one read instructions and charged it. Never turned on at all. Called this sites customer service (they ROCK! there are none better) and they sent a new one no questions and when they finally recieved the other one my card was credited back the money. Mind you I was even shipping to a APO address. Second one comes and it turns on and charges ok (when youre charging it you can't use it). I am in Iraq and there is nothing but flat terrain for the most part except in cities. SO I try it out in open area, no obstructions for runs and walking. GPS is fickle on tracking at best and the menu really takes some getting used to. I thought well, even as an emergency backup GPS it would still serve its purpose. What I didnt realize when I bought this was that you're only gonna get about 500 charges off this battery (if that) according to the manual, then you gotta send it back to Finland to get a new one installed cause they dont do it at the watch store anywhere in US. Why not just make it so you can replace the battery at home? Anyway, you can do the math on how long that will last. Not worth it. Here's my question, has the X10 fixed these issues? I saw the charger offered as a free gift so that helps I guess, but the other stuff in my mind is more important.

BTW the Garmin Foretrex 101 is the heat and no matter what I try I keep coming back to this one for reliable GPS function. It's small compact, GPS locks on anytime everytime even after traveling to another country it took like 30 sec to lock on, it even locked on inside the airplane in a window seat in flight!, and runs off 2 AAA batteries. Only draw backs are its not really a watch you can leave on during youre normal day to day activites, so I use my Suunto Vector for that. Also the wristband pins in Garmin Foretrex models SUCK and rip right out guarrenteed (metal pin in plastic hole). London Bridge Trading Company makes a see through velcro wrist carrier and it made it through my entire tour 16 months no issues. The two together are spot on. Good luck out there, hope this helped. Let me know about the X10 thanks.

thank you
