Best setting for distinguishing rock and sand on the dff1uhd

[BooBoo]

Looking to find the best menu set up for finding rock and sand on the dff1uhd sounder with the l265 transducer.

It seems to me AUTO with BD turned on should do it. Maybe @Deep Blue has other insights.

I have been playing with the auto but my rock/sand transition seems sometimes hard to distinguish. I should mention too that fishing fairly shallow waters. Usually 120 feet and in

BooBoo,

You have the best transducer (B265LH) for use with the DFF1-UHD's Bottom Discrimination capability. This setup should provide you with the greatest performance in the detection for Rock, Sand, Mud, and Gravel.

Be advised that the Bottom Discrimination feature works between the depths of 16-328 feet, and at a maximum speed of 10 knots.
