We have 3 FREEDOM7 shark shields in our family. We have had great success with them. 9 shark encounters, 9 sharks got belted. Awesome results!
We live in the south west of Western Australia where we encounter many different kinds of sharks, and use our FREEDOM7s for snorkelling, freediving for abalone, and when spearfishing in deeper waters.
Our FREEDOM7s have deterred Great Whites, Bronze Whalers, and a Grey Nurse shark.
