I looked online for pontoon rentals and the only 3 that I could find were Espyville, Jamestown, and Pandanaram. I was hoping for one below the causeway. I called Jamestown and their prices were nice, but none of the pontoons had a fishfinder. So, if you know of any other pontoon rentals below the causeway, please let me know so that I can give them a call. Thank you.

I have a portable flasher unit you can use.

Thank you for the offer. Is it a fishfinder or a flasher like a vexi that you would use icefishing?

Get yourself a Hummingbird portable battery operated fishfinder. I have one and it only cost about $100. comes with a clamp u can use on docks or a boat. gives water depth,water temp and shows the fish.

Thanks for the offer, but I think I'm just going to rent from Espyville and pay to rent their fishfinder. It's too bad that Jamestown doesn't offer the same service. It was very kind to offer me your flasher though. Thanks again.

Slabdaddy, I have a Lawrance fish finder that I have the transducer mounted on a piece of wood that I clamp to the back of the the boat with a C clamp.  It has gator clips to hook to a battery.  You can borrow it if you want, its just sitting around my garage not being used. dont know where you could clamp it on a toon but if you want to try im in sharpsville area, shoot me a pm.

mak, a friend of mine loaned me a setup exactly like that. It worked just fine. Thanks for the offer though! That was very kind of you.
