Called HB yesterday AM and complained. Got a box today with A new HDSI transducer and filters included. No charge!!! all for free!
In the process in swapping the transducers out. Should make a lake run this weekend or next week to see how she does.. I have had my 797 for over a year but was never happy with the SI function. SO I hope this bigger transducer will help out some. If not,,,well I'm not out any $$$
