I often see

to recognize.


That certainly seems plausible but I haven't had any interference while
running a Garmin transducer at the starboard stern and a Humminbird at
the port stern separated by about 6 feet. Two identical units probably
would be more troublesome.


I run a Furuno and a Lowrance fishfinder at the same time on Yo Ho. The
transducers are about five feet apart at the transom.
