Kayak Depth Finder

[webbja]

I have a Heritage Redfish 10 and was wondering about the best depth finder to get for a kayak. I use my kayak in saltwater and freshwater. Also I fish in shallow rivers with a lot of rocks so it would need to be able to detach from the kayak. Any info would be great thanks.....
