dive planning

subsurface: plan and track single- and multi-tank dives using air, Nitrox or TriMix.

Pros: stable, does its job, no crashes that I've experienced. I personally think deco planning can be made simpler given cylinders/mixes, starting pressure, SAC, and depth.

Cons: none.

Alternatives: none?

Why do I use it? Plan the dive, dive the plan. Would I like to change? No.
