Default B60 vs B175HW

Looking at B60 or B175HW for shallow water grouper. Less than 50'. Mainly interested in bottom discrimination. Will be running Simrad NSS unit. Any opinions of either of these?

A narrow cone is important for grouper fishing so B175H-W is not a good choice, B75H or B175H is what I would recommend.

You want high frequency for this type of fishing

In 25' of water at 200khz, B60 covers 5' of bottom and B175HW covers 10'. I was hoping the greater sensitivity and wider cone would allow me to cover more area.
In 25' of water, B75H covers about 4'. B175H covers about 3'.
Do these differences in cone angle in 25' really make a difference in finding rocks, ledges and hard bottom?

Rule of thumb -
narrow cone for tracking bottom
wide cone for tracking fish (unless the fish are right on the bottom)

I've read that when searching for groupers the experts are looking for small holes in the bottom, they are looking for what they call "tails", which is something they observe at the underside of the drawn bottom.

If you are just searching for structure you can use StructureScan for this and then B175H-W would be an excellent 2D transducer.

Assuming identical transducer characteristics except cone angle; would a 25 degree cone angle in 25' of water covering 10' of bottom be the same as a 6 degree cone angle in 90' of water, also covering 10' of bottom?
