I use the same battery on mine. Purchased it from Cabela's with charger. You will have plenty of juice to run your unit. Like Angluh said, the depthfinder is definately worth having aboard the yak. Not sure how to help you regarding the puck though.
Thanks for the info everyone. Upon further research it looks like I can mount my 160 on the kayak with a little creativity. I'd prefer to have a combo (Sonar/GPS) unit even if it does require a 12-volt battery rather than AAs.
There is a good website that shows some various installation approaches if anyone is interested.
Three-fourths of the Earth's surface is water, and one-fourth is land. It is quite clear that the good Lord intended us to spend triple the amount of time fishing as taking care of the lawn.
