Diving 103: Freediving and Underwater Hunting

Three Types
Near Shore (reef, kelp beds): water depth down to 100 feet
Deep Water (walls, edge of canyons): depth down to 300 feet
Blue Water (open ocean, off the continental shelf): depth down to many thousands of feet


Equipment


Fins
Long blade--for strong leg swimmers and advanced divers
Scuba fins--for occational freediving and weaker legs
Split fins--for occational freediving and weaker legs, more efficient than scuba fins


Spearguns
Three Types
Rubberband--surgical bands used to propel speargun or hand sling
Pneumatic--air powered (CO2 cartrige or pump action)
Spring loaded--spring powered

Information
For reliability, get the rubberband type (fewer moving parts). Riffe makes excellent rubberband spearguns. When the rubberbands start to tear, it is easy to replace the propulsion system. Keep in mind the kind of fish being stalked, the terrain, and visibility. West coast (U.S.) divers benefit from a 48 inche speargun. In low vis spearfishing, only use a hand sling to avoid spearing your buddy or other divers (better yet, don't spearfish is the vis is bad).
