You should use omni rotational for finding subs Xab, I believe it has better range. Then narrow it down with single beam.

But considering single beam sends all the energy down a 20 degree cone but omni-rotational does the same thing but rotates the beam around the whole area that the sonar covers so why there would be a difference I don't know.

its mainly a time difference to find the contact comparing 240Â° and 20Â°
say 12 times once you find again the ping return.
less than 1 mn of work with single beam (pinging 4 to 6 beams usually), when on 240Â° it is near impossible to plot the contact ... or on much more time
