I have a total scan transducer that 2 screws are broke off in. Should still mount fine with other 4 screws. It happened because Lowrance sent the LSS2 bracket with the Elite 7 Ti TotalScan and the holes almost line up. In the entire ordeal I ended up with a new transducer and an extra bracket. You should be able to use the transducer with other head units with a $30-40 adapter. It came with an Elite Ti 7 Totalscan. If you're careful with a drill press you might be able to get the 2 screws out.
I live in College Station and occasionally go to Dallas or Houston. Buyer pays shipping if we can't do face to face. Price is $150 half price of a new one.
