Re: Mounting 2 transducers
You might get interference between the 2 units if they are running at the same frequency.
I have 2 units, both mounted on the transom, starboard side, as I have a kicker motor on the port side.
When there is someone up front using that unit, sometimes I need to turn off the helm unit.
That's fine most of the time, as I am busy driving the boat, and I have the chart plotter to keep my on course/at proper depth.
The front sonar unit is really a nice convenience for ME. It keeps people from constantly asking "how deep it is", "are there weeds here?" and "are there any fish down there?".
