Suunto Stinger Advanced Dive Wristop Computer Watch

I've owned one for almost two years and the best feature I can think of is that its very simple to use. It takes care of all the administive details for you. Depth, dynamically keeps recalculating how much time you have left at your current depth, safety stop timer, when you're topside it keeps track of your surface intervals and refactors for your next dive. No flying warnings appear as appropriate.

It made me a more aware diver. When I started using it, I noticed it kept beeping at me telling me I was ascending too fast or descending too fast - ie breaking rules. It was annoying at first but the sad fact was that I was breaking rules and didn't even know it and I was putting myself in a higher risk category. I paid attention to the warnings and I think I'm safer for it. Now my Suunto doesn't beep much when I dive.

The algorithm it uses is very conservative so I'm comfortable.

It is not air integrated so you still have to look at your pressure guages. But if you rent your equipment or you're a new diver, this is the first thing to buy (literally buy it with your mask, fins, snorkle, and wetsuit) before you start going out for regulators or BCDs and stuff like that. It just takes makes diving more enjoyable. Its especially useful for multiday dive trips where you're renting gear every day...it keeps track of your no fly times which on long dive trips can extend more than 12 hours so the computer tells you when not to fly.

Titanium is very light. I use the plastic strap mostly because its easier to put on and off with a dive suit. The Titanium strap looks cool though. I generally don't wear it as a watch...its huge and you can tell its a dive computer - if you're 6'5" maybe you can use it as a watch. I do wear it on diving vacations though as my primary.

It has a bunch of features too nitrox mixes, dive planning, and a whole bunch of other stuff.

An interesting thing is that if you break too many rules or do something that puts you in a higher risk of microbubbles and things like that, it will give you warnings telling you not to dive. I received one of those infractions once. Consider it your diving police officer. It is pretty merciless though.

When I get home I download the data to my computer and it tells me exactly what I was doing.
