Shark Shield

I'm using a freedom 7. I put a short leash on it so I don't lose my $500 insurance policy.
The unit needs water around it to function properly, the colder the better.
I run the lead cable through a scupper hole and the battery pack sits in the inch or so of water on the deck.
I've had one encounter while running it and as far as I can tell it worked, spooking the shark away.

just remember to turn the unit off when you land, otherwise you'll have to get zapped a few times to turn it off when the kayak is wet.

Based on the site, "Operating Temperature Between 12C – 40C (53.6F – 104F) Lower temperatures will reduce the operating time" So it seems like colder may not be better

This is my entire week this week
strikeout on the erroneous statement

Someone should really figure out how to wire one up to a battery.  Game changer!

I agree. I might give it a try since my battery is dying and it’s not replaceable.

I wrote to the company and asked them to make a kayak specific one with a larger battery, or the ability to attach an outside power source. They responded that the Freedom 7, designed for divers, was fine for kayaks. I wonder if their patent is up? Probably not a large enough market for someone to do some reverse engineering. 

Anyone know anything about the SharkBanz 2? Seems to be a more affordable option to the shark shield. Although it seems they only make the ankle bracelets, I think you could hang one or a couple off the side of the boat?

Australian eBay sells battery replacement for SharkShield as well.  But would imagine connecting it to an external source should not be a problem given that we can find the battery that provides the proper voltage.

Dont waste your money on this. It was my first option when I was searching for a shark deterrent options. After some encounters. But if search enough you’ll find it dont work at all.

Here is a video on replacing the battery:

That's looks a lot easier than I imagined. Not bad at all.

Thats awesome! Now I dont need to worry too much. If only we can swap them easily when on the water to have spare battery.

Thanks for the battery video replacement mark. Bookmarked.

Good to know. Thanks for the info!

This is the place that has replacement batteries:

Seems like another side gig for Chet -- maybe when he triples the battery life he can increase the output so that it works like a stun gun on the sharks

Right!  Find a way to make the protective range like 100 yards.  Sure, it would fry your ass if you touch it, but it would take only a few to wipe a whole spot clean of sharks!   

Would it work to make a pigtail to connect an external battery to the charging poles?

Not sure if the circuitry excludes operation while charging.
