    This one I bought for my buddy so we can both have the same chances of keeping the man off of us. Mine is the best part of any gear I have purchased just simply because the feeling you get from knowing all is good out there in the water... Right on Dano

    peace of mind

    Posted by Sven Anderson on Mar 26th 2015

    I wear mine for summer wreck spearfishing where great whites and tigers are way too common. It does work as advertised and I wear it religiously. ONE issue that keeps biting me in the ass is if you forget to turn it off before you get out of the water you will get one hell of a pulsing zap through your body. Also if you are lying on the bottom or wear a calf knife you will also get occasional pulses in your legs. Nothing really painful just annoying, but then you know its working at least.
