I use Stinger for 5 months, but my decision based on further observation and after many discussion with some Instructor and Divemaster fellow. They suggest (and I agreed) that Stinger support Nitrox up to 50%. The disadvantage is since it is not a tek dive computer, you can not switch the gas mix down there. You only can use one type of gas mix during one dive. Additionally it's better to put your computer in EAN mode, so you can change to any gas mix for the next dive, including Air which is EAN 21.
This wrist dive comp is highly recommended since the model is quite "normal" that you can wear in everyday life. The cover and bracelet comes in 3 types: Rubber, Metal and Titanium.
If you a computer geek, you can also buy a PC Interface and learn your profile in your PC. It's all worth buying ...
Happy diving from Bali ...
