Since you're profile isn't really filled out and we don't know where you're from or your certs, we're sort of at a disadvantage here.
I'll assume that based upon your comment you have nice diving where your at. We'll if we were only so fortunate.
Why don't you come to my quarry and we'll go find the bottom at 120+ffw, 36-38degreeF water temp and >10ft vis and let's see how you do.
I can't tell you how many 'experienced' warm water divers call dives in our quarry because they can't handle the gear, the visibility, and/or the cold.
It goes both ways.
