How does a portable fish finder work?

I am taking a fishing trip to Ontario this August for Pike and Walleye and will be renting a plain, 12-foot aluminum boat instead of taking mine up. Mainly for walleye I would love to know the depth I will be fishing and am looking into portable fish finders. Basically, I am confused as to how the sensor works… do you actually throw it in the water and it goes down to the bottom then tells you or throw it out over the water and it bounces sonars to the bottom, also could you just set it in the bottom of the boat to get readouts? Thanks in advance.

    Usually you’ll get the monitor, and attached to it you’ll have one power cord, and one sonar cord that hangs over the side of the boat. I like to attach it somehow so that it’s not damaged while moving. They do bounce sonar to the bottom and back up.

    They work pretty well. There might be different kinds, the one I used was digital, but I’ve seen scrollers that show the bottom and fish with a rolled paper.

    I’m going to the St. Lawrence next week and going for pike and walleye myself. I hope we both have luck, but like they say, a bad day fishing is better than a good day at work.
