Never ever would I or will I dive with a Grrmin. For easy dives (PADI Open water) no one needs a computer like that – a simple ZOOP is perfectly fine/reliable.

For “advanced dives” (multiple dives, mixed gas, gas switching, oxygen, fair/solid amount of deco time) you need something you really rock solid – Petrel/Perdix, OSTC+/2/4 are good choices.

For dive guides (DM, Instructor) a D4i/D6i is plenty enough – and reliable.
