When it comes to electrical systems aboard boats, Arild Jensen knows his stuff. Here's where to ask the simplest or most complex questions about marine electrics.

Two Sounders one Transducer

Postby AllanY » Tue Jun 15, 2010 5:33 pm

Does anyone run two sounders off the one transducer??

I have a Furuno GP1650DF on the fly bridge and I want a sounder in the saloon station as well.

I already have a new hummingbird.

Can you run dissimilar sounders through a splitter??

Sounders are like radio transmitters with the sounder transducer needing to be matched to the transmitter. Unless the circuit is designed to include a switch to transfer from one transducer to another it will not work well. If you have identical transducers with identical frequencies you can sometomes switch but like an VHF antenna switch only one at a time can be used

I have two sounders running off a single transducer, they are old model Standard Horizons. The lower station is an SP-100 Model, the one on the flybridge is an RP-100. The Key is that the "RP" is a simply a Repeater from the lower helm.
