Tested your question.

Range = 7nm
Sea State = 3m swell
Profile = 456ft layer

LA688i was heading 090 at 80'
FFG was heading 000 and was to the east of the LA

In trying various directions on the single beam the LA picked it up everytime, BUT it would only pick up every 2nd or 3rd ping irrespective of active range setting or active type. It might have something to do witht he seastate, i'll give it another go when I get time.
