At one point, I was watching Kambute - he had one fish in is pocket, another in his left hand and the loaded Hawaiian Sling in his right hand. He swam down into this cave and I saw him shoot the sling. I could tell he hit something because the sling was shaking violently. He struggled for about 20 seconds to bring something up with his one free hand, but in the end, ran out of air. He did however get a nice Tigre (Grouper), shown here.
