Fishin' Buddy 1101 Bottom Line Portable Fishfinder Kayak Canoe, HEAD UNIT ONLY. No mounting bracket No Transducer. Head Unit powers on. Takes aa batteries, not included. I'm not familiar with this depth finder but I feel like it's missing a Transducer, the plastic shaft and end cap is empty? I tried using this and it didn't read depth. When I bought this at a estate sale it still had the screen sticker on it and appeared it wasn't used yet. I took out on my kayak and couldn't figure out how to use it or it's missing Transducer or it's broke. Selling as is.
