Great Dive Computer/sports watch

I have not been in the ocean with it yet. I did try it out in a pool and it seems to do everything they say about it. I'm going to Barbados in a few weeks and that will be the real test. I do like the fact that the heart rate monitor is built in to the device so you don't need an external strap. It also does everything that the Garmin sports watches do, so it is an all in one watch/dive computer. I also bought the titanium band and it makes a great looking watch. I plan on changing to the silicone band when I dive. It is so easy to change them! I'm loving all it has to offer and it will do much more that I will ever do with it.
