What depths do you usually fish? It’s pretty good for what it is for a shallow water transducer. The chirp on it is far better than the p66 transducer that obviously doesn’t have chirp. I have the 3in1 on my hds9 and p66 on my 7. The down and side scan are pretty much useless when your fishing 150+ feet of water. Mine came with my hds9, but if I was to spend money on it I would spend a bit more and go with a Tm150 or Tm165hw.
