just looking for a fish finder i can easily mount in my jonboat. i know i could just look at websites but i first thought i should hear what u guys think of the products out there> any input would be appreciated>

I use an Eagle FishMark 320 portable.  Great fish finder for the money.

I just bought a Garmin (color) and I am happy with it.  It also did not break the bank as far as cost.  I only say that because I do have a fishing budget.

Hummingbird 525; pixel 320V x 320H, ultra high contrast 5" LCD with 12 level grayscale, 2000 watt peak-to-peak power output. All for $160

The humminbird 565 was on-sale at Dick's Sporting goods for $160 after rebate, have not installed yet but seen a lot of good reviews here on other post.

Humminbird 565 > than everything less than $200.

I use an Eagle FishEasy 320C on my kayak and it's a great unit for a small boat.  Very compact and has a very sharp color display, even in bright sunlight and wearing polarized sunglasses.  I use a small sealed lead acid 12v battery and never come close to running it down.  I've been very impressed with it so far.

thnks a lot for the info guys.  really narrowed it down to what i was looking for.   and the winner....hummingbird 565   thx
