Hello - this was my depth sounder / fish finder. It was last used a decade ago ! It was in full working order but when the boat was sold the new owner had his own so I elected to keep it. The transponder had been fitted into the keel & the electrics were fitted behind panels so they had to stay. I was going to get in replacements but Covid came & it was another job that never got done So here it is, I have no means of checking it out but it was working so if you buy at the price being offered then I am prepared to give a months warranty, if you make an offer then it is on a bought ‘as seen’ basis.
