Geoff, what kind of fins are you using? maybe with different fins you can get down faster..i notice this as a difference between lastic and carbon fins for example...but please note im NOT encouraging you to make sudden increases in your depth..you need to progress very gradually thats the safe way..all im saying is that the right choice of fins could make some difference as you gradually progress and in turn give you some more time on the bottom for the hunt...
Good Luck
