Fish finder advice

[Longtrav]

Ok so after a few trips out I see the need for a fishfinder. I would like a fishfinder that can obviously take some water. I would like it to be able to take a turtle. I would like to mark locations . Other than that cheapest that is durable. I have a predator 13 with battery bag and scupper hole transducer mount. Thanks

You may want to look at the Humminbird PiranahMax 176i.

I have used Humminbird fish finders for 20 years without having any problems. They are water proof to survive torrential downpours and turtles. This particular model is a basic fish finder with a GPS at a reasonable price.
