37’ center console the one in my signature, Shallow bottom fishing 30-150, Wahoo trolling 150-800, deep dropping 500-1000, Tuna fishing 3000-6000.

I also would like something that will work in very shallow water 2-4 feet at high speed 40-60 mph. (If that is even possible)

The GT51 reads up to about 40 mph but loses the bottom after that.

For high speed on a boat that size...I would recommend a fairing mounted ducer such as the B275C-LHW. ....at speed a large boat develops a boundary layer of disturbed water flow that can inhibit sonar to some degree.
a fairing puts the ducer face in clean water.

As to the CM275 vs the PM 275...the CM is used for tank mounting...the PM for pocket mounting.
