dive guages computers do any show your ascent rate in meters/feet per min, I know they all show depth so can be worked out !

Suunto Vyper (and others) have the graphical 10m/mins representation, but I guess you want a numeric rather than graphical display if I read you right ?
It warns you if you're faster and does at least show if you're slower.
Just a thought.
