What is a good fishfinder for use in a kayak?

I’m an avid kayak fisherman, and I’d like to add a fishfinder to my boat. The kayak is a polyurethane sit-in model, and I want a fishfinder that is relatively compact with a transducer that can be epoxied to the inside of the hull. The hull is somewhere between 3/16″ and 1/4″ thick.

Color is not an important feature for me, but a grayscale screen would be preferable to strictly black-and-white. The unit does not need an internal battery; I’ll provide power for it. I would like a model that has fairly high wattage to the transducer. A narrow-beam or two-beam transducer is preferable to a wide-beam one, since I’ll be moving slowly and stealthily. The unit does not need a cover, as I’ll be removing it when not in use.

I’m sorry about all of the specifics. If you know of a good unit that’s compatible with kayaks, I’d be interested to know about it even if it doesn’t match all the specifications. I’m more interested in identifying depth, bottom structure, and thermoclines than I am in spotting actual fish, although a unit that reliably can identify suspended fish would be great.

Help picking out a Fishfinder?

I am looking at quite a few fishfinders…here are my choices for this price range ($150)

Garmin Echo 200 dual beam sonar

Anyways my price range is around $150 and if you guys have any suggestions please say them…All i need is a nice fishfinder that can really show schools of shad really well.

Also if any of you guys have these fishfinders, feel free to review them so i know which ones are the best
