Default Transducer for bottom discrimination below 450 feet

Hi all,

First post, so I thought I would make it a worthwhile question.


Salt water, 22 foot aluminium with outboard.
Gen3 Lowrance (Chirp, obviously) Sounder/GPS

Looking for the best transducer for depths generally below 450 feet.
Bottom definition is what matters to us most.

So far looking at Airmar SS175c-m and TM265c-LM (but no sure if they are supported by Lowrance). Could also mount a B265 with fairing on a bracket out the back. ie do the above come with the blue connection cable.

Does support matter or can you just wire them up and away you go.

Also, does the SS175c-m perform as well as the TM265 (noting that the 265 is two trans in one)

Can I run two transducers at once on a split screen or two different Gen3 head units (if I also decide to also get a High Wide later)?

Open to all ideas, all help appreciated.

The Gen3 is single band Chirp, meaning only one Chirp frequency. Gen3 supports the ss175. The 265 would have to be wired with 2 pigtails and manually swapped out from low to medium
