Portable?

 Are portable fish finders the way to go on a kayak, or should I get a non-portable unit? Why? 

guess it depends on your boat and your budget.. but definitely on canoes the portables like the " my fishing buddy" line are the way to go.

bear in mind a lot of the portables are clamp on styles with giant "C" clamps designed to fit a lot of different surfaces, but mainly flat ones. humminbird is the brand i'm most familiar with, spent a lot of time on their site, and they do have portable units that are basically a "fish finder in a bag" style. that might work better for you than the other style i mentioned.

honestly, after looking at a LOT of FF installations here and other places, it doesnt seem to matter, as long as you have one you are happy with can afford and works well for you.
