... of course it is also the only one that many people can use throughout a full triathlon. Overall, I think this is an excellent product, but I agree with some of the others here that Garmin hides the ball somewhat in its marketing/advertising.

First, this is the only waterproof GPS watch that I've seen and it also has the battery power to get you through a full Ironman. As such, I can put it on my wrist and not worry about it until the end of a race (with the exception of hitting the lap button to change events/transitions). The multi-sport function that lets you set up the watch for triathlons, duathlons, brick workouts, etc. with or without transitions is fantastic. For me, this makes it great and the best solution available.

I do find the distance calculations for swimming absolutely ridiculous. As far as I can tell, swinging your arms for every stroke is what throws the watch off so much... interesting that it seems to be a problem based on it being too accurate. I've done a 3000 yd pool swim to find a claimed distance of over 3.2 miles. I do think Garmin should include a "Swim" function that just turns off the gps if they can't figure out a way to combat this problem... generally you know your distance in a pool or in a race, so the biggest interest (at least for me) is the timing of the swim.

Someone here said that biking with it on his/her wrist doesn't work, and I have never run into an issue with that at all. I find it works perfectly during biking, running, hiking, etc.

I will say that the price here seems too high. I've seen it for less.

Overall a very good product that people just need to understand has some limitations. -- Best Triathlete GPS available
I have had my unit for less than 24 hours - In the first 15 minutes I easily setup up the watch & paired the heart rate monitor. After work, I went running with the new Forerunner unit. It was EASY to use and READ throughout my run. Early this morning I setup the ANT+ which easiliy paired with the unit. I uploaded the history and route to the [...] website with a simple click. Then I stared in amazement at the recorded details of my run with pace, elevation changes, the exact route, HR zones, etc. I can highly recomment this product! Now that I have this excellent technology, the only hard part that remains is the work of actually burning up the trails! -- Amazing Training Tool!
This a very good equipment to follow the athletes on their trainings and races! Easy to start using, but at the same time, a few difficult to set the screens and to get connection with PC.
Nice acquisition! -- As I expected!!!
kind of big but works great. wasn't sure the gps map was going to work in other countries completely, but it still showed exact path. -- good
