About to dive down the wall
 

Looking for fish downslope
 

A pesky Caranx melampygus laughing at me.
 

Just got a snapper, Macolor macularis.
 

Swimming up ....
 

Oops, the gun floated up to the ceiling and snagged ...
 

Got everything, headed for surface.
   

Keeping a sharp eye out for visitors from below.
 

At the surface, leaving my photographer buddy to deal with the sharks.
   

Grey reef shark attracted by noise of speargun, and smell of blood.
