The ad said fishfinder was ready to plug in and use and was not. I got it and in good looking condition but had no transducer. So I ended up buying one. Then when I used it it would work but the depth isn't always correct. It stays at 1.5 ft depth every so often. So I can't say it was a good deal since I would've preferred to buy others that had all parts and tested to work. Be ware shoppers if it ads "don't accept return's" or says "tested" then you're taking g a chance on the item.
Exactly what I was looking for. It was plug compatible with my old X51. My old transducer does not have a thermocouple so temp doesn't work which I knew. Shipping and packing were excellent.
