It's 12V. It will not electrocute you! You may get a small shock at the
most, but not enough power to hurt you. It is a kayak, not a bass boat.
Get a small 12V gelcell battery and use that. The fishfinder will run for a
couple of days on it. If FF and GPS, probably 20 hours. Talk to your local
burglar alarm place and they may sell you the battery cheaper than any other
place. You will need a god charger for the gelcell, so you do not cook it.
But should be cheaper than a pelican case.

I'm looking for a powerful portable power solution to use on my kayak in
fresh water.

I'd like to:

1) mount an Absorbed Glass Mat Marine Deep Cycle 12V battery inside a
large
waterproof Pelican case. The Pelican case will be either tied down or
mounted to the kayak.

2) hook up a Marinco SEALINK Receptacle with Alligator Clips to the
battery
( http://tinyurl.com/4nme4 )

3) plug a Wagan 3 Way Socket with Battery Analysis into the Marinco 12V
receptacle
( http://tinyurl.com/46j7v ) - is there anything available more
sophisticated than this?

4) plug my electronic devices into the 3 available sockets on the wagan
device with the ability to determine the status of the battery.

Attaching the Marinco Alligator clips to the battery, and hooking up the
devices will all take place before entering the water and never take place
while on the water. The electronic devices I'm using require little or no
interaction. If interaction with an electronic device is required, it will
take place as far away from the battery as possible and only if my hands
are
dry and the water is calm.

If conditions get too rough, devices are turned off, pelican case is
closed,
sealed, and waterproof.

The pelican case lid will be opened slightly to allow ventilation and
opened
and aired out periodically for greater ventilation.

My goal is to have access to portable power on the water with my kayak
without the risk of electrocuting myself or anyone else!

I'd like to be able to relax and use my power supply without being anxious
or uptight with concern over electrocution.

Is this approach safe?

Are there any other precautions I should take into consideration?

what to do, what not to do etc.

Thanks for any info.
