Transducer Shield and Saver is what I have on both of mine. I highly recommend it.
No I have lowrance.
Yep, but how much does a new transducer cost?
I just hate when things like this are priced ridiculously. I feel like they jack the prices up on some of these items because they know they are the only option on the market.
