I have a Sailfish 245 DC with a simrad evo 3. I have been struggling to get useful readings on the echo since purchasing the boat (last season) and the dealer tech just confirmed that (1) the installed transducer isn't working and (2) even if it was working, it doesn't support the echo sounder (it has down-scan, side scan, 3-D structure scan, but not the basic echo to show the fish and make use of the various color pallets and symbols, etc). They confirmed this by attaching a new transducer to the unit and lowering it over the side of the boat. The new transducer started working with all the functions except the echo. I am not waiting to hear from the dealer what type of new transducer is recommended -- whether a replacement or an additional transducer. In the interim, any input from the group of the best transducer for a full echo readout would be appreciated. BTW, this is a transom mounted transducer. The transducer which was supposed to have originally been installed was a XSONIC P66 Plastic transom mount transducer 50/200kHz Black 9 Pin connector. Thanks.

My suggestion would be a thru hull transducer. Air-mar makes great transducers. I would look into a tilted element transducer. Mount it about a foot either side of the keel. Make sure that it is not mounted in front or behind a strake. You want it to be in clean water (free of turbulence). You are probably getting air bubbles from the turbulence caused by the propeller.

I’ve got a simrad evo2 with 2 transducers. One is an LSS-2, it does depth, sidescan, and down vue. It does not see fish. The frequency band that gives all those nice structure pictures won’t see fish. The second transducer is a thru Hull B-175M CHIRP. It sees depth and fish and water temp. It will not make pretty structure pics, again wrong frequency band.
So, to me you don’t have a problem with the simrad unit, you just don’t have a transducer that does what you want it to.
Additionally, a single simrad unit can’t run both CHIRP and the structure scans at the same time. One or the other. Or get another simrad unit and network them together. There is a work around, you can set the CHIRP to 83 kHz then go un-pause the structure scan. It works in that you can see both fish and structure at same time, overplayed with each other on the down vue pic, but you lose all the benefits of CHIRP which I find to be better for finding fish 99.9% of the time. I will sometimes use the structure scans to find and mark structure, then switch back to chirp and go directly over it looking for fish.
