The Shark Shieldâ„¢ Freedom 2 unit is a compact, versatile and lightweight personal unit designed for snorkellers, swimmers, surfers, scuba divers, spearfishermen and kayakers. This unit has a 2 hour rechargeable battery.
The main body of the unit, comprising the electronics module and a 2 hour rechargeable battery pack, is enclosed in a protective neoprene pouch, which is attached to the lower leg. The unit is fitted to the lower leg via a neoprene pouch. Attached to the pouch is an antenna housing the two electrodes, which trails unobtrusively behind the user. These two electrodes propagate the field into the water, therefore both electrodes must be fully immersed. The Freedom units are an excellent alternative to the specialized Scuba unit for scuba divers, who also surf or free dive. In fact they are fast becoming the most popular unit for those who scuba dive only. In tests conducted to date the Freedom 2 has deterred sharks at distances of up to 6M, but with an average distance of 3-4M from the unit. If using this unit for surfing, please see surfing instructions below.
