looking for a portable fish finder

[vbfishing4]

I am looking for a portable fish finder. I was wondering if anyone had any suggestions for one worth spending money on. I'm not looking to break the bank, I'm just a college kid with an obsession and not much money! I would be using it either on my kayak or on my Jon boat. Any suggestions would be helpful. Thanks!

hbird 110--100 bucks at wal-mart. 6 aa bats....just unplug the the power cord when you done or it will drain em everytime! Once you get the sensitivity dialed in its decent

Humminbird also has many other models that come as portables or can be made portable. Basically any of the PiranhaMax, 300, 500 or 700 series units can be put in a portable case. The Fishin’ Buddy series units (like the 110 that SLABMAGNET mentioned above) is portable as well.

You will want to look at how you will be mounting the unit and its transducer on each boat. We make a kayak transducer mounting kit for some of our transducers: Transducers » Kayak Mounting Hardware
but that would mean you have to buy a second transducer (one for the kayak and one for the jon boat).
