I use mine and feel better doing so.  If I get eaten by a shark while using it then my opinion will change.

IMO, I think the SS might deter sharks from hanging around your yak but I don't think could prevent "top water explosions".  It's like trying to stop a freight train goin full speed...

Of all the encounters with GWS in kayaks how many were top water explosions and how many were "exploratory"?

Interestingly, If you read the studies, the evidence suggest it actually works better on the ambush attacks than the exploratory.

Although it might seem counterintuitive, that's what the (one and only) study shows.

If they do some studies at Ano Nuevo, I'll buy one right after...

I would like to see them do a double blind study with a towed bloody elephant seal carcass with a Shark Shield strapped on to it in front of Ano Nuevo or the Farallon Islands.

Shark shields are for pussies...unless it's September or October in the red triangle. This is a good time to tell Mdoka Matt how much you appreciate him as a friend and how he's the baddest halibut fisherman you know and that you'd love to go on a mission with him sometime. Hey Matt ol buddy ol pal... :smt008 :smt006

Here is the relevant study:

https://sharkshield.com/wp-content/uploads/2014/04/Effects-of-an-Electric-Field-on-White-Sharks.pdf

Table 4 is the important info for kayakers. When they towed a seal decoy (off the coast of South Africa, where the sharks like to launch themselves when attacking seals---think "shark week"), they got 16 breaches and 27 surface interactions with the SS off. With the SS on (and a comparable number of experiments), they got 0 breaches and 2 surface interactions.

Of course, nobody knows why they got those results, but the theory seems to be that a shark has to expend a lot of energy on a breaching attack. So, the shark spends some time checking out the potential target, and the electric pulse is apparently enough to make it look like it's not worth the effort.

On the other hand, if there is feeding frenzy, the SS had no effect, presumably because the other positive reinforcement overwhelms the negative from the electric pulse.

At least that's the way I remember it from reading it a couple years ago...
