Using a Fishfinder in Your Float Tube

I use a fish finder on my float tube and pontoon boat and have found it to be beneficial in locating the fish. I seem to have a more successful fishing trip when I use one, as oppose to not using one.

So far, I have found 2 kinds of fish finders that are compatible with using on float tubes and pontoon boats:

1) Fishing Buddys are made by Bottom Line. These are mounted in a "side holder" and stored in a fish finder keeper. Prices range from $70 to $550 depending upon differences in models, features and pixel displays. A Fishing Buddy radiates sound waves on the side view finder, as well as, what's underneath you. It shows depth and bottom structures, large fish, small fish, and water temperatures. They run on three size C batteries. I'm pretty sure that the Service Charge is a minimum of $99.00 to fix it if they break...even if there's a loose wire. And you have to ship it back to Bottom Line in a box when it needs repair.

2) Hummingbird Fish Finders are made by Hummingbird. These can be mounted on a VERY HEAVY THICK piece of rubber (found at shoe stores). Mount the Hummingbird to a long rubber piece with screws, leaving a long side piece in order to stick the rubber under your frame (on pontoon boats); AND, tie the rubber piece down with a strap on your float tube and pontoon boat. So it should be very secure. These fish finders run on a one-12 volt battery. The battery can be stored in a side pocket....or in the back of your float tube. The finder structure can then hang down in the water between the tube and the seat. The price ranges between $130 to $500 depending on different models and features and pixel displays. It sends a 2-beam, or 3-beam sound wave down. It shows more of what's beneath you, depth, and bottom structures, large fish, small fish, water temperature and some, if not all, come with 'speed of the boat' so you can depict migration of fish, and water temperatures. You might be able to purchase a Hummingbird from a local bass shop. The Hummingbird can be stored in a hard plastic 6-pack ice cooler in order to keep it from getting banged around while traveling. I also believe that both models can be found in a Cabelas catalogue.

Also, just a note on something that has recently been brought to my attention, is that these fish finders can go to depths in fresh water to 240' , with a side distance of 120'. But if you happen to be fishing in 20' to 40' of water, you would probably like to "manually change" the depth range to maybe 60'. That way you can pick up more "contrasts" and the small blimps/images will become larger and clearer and more pronounced.
