2 Transducers

Transducers


After a long story, I am thinking about putting a second transducer in the boat.

The reason for this was that I had a furuno fish finder. I upgraded to a raymarine this year. My transducer is raymarine and do to unforeseen circumstance's I will be replacing the furno transducer with a raymarine. I have a c-series for this.

I have a perfectly good furuno transducer. I thought is that I would mount my furno in the cockpit for the chunk.

My question is whether 2 different transducers in the boat, would affect the preformance of the to fish finders.

How about some insight im also curious about running two fishfinders at once.

I have 2 Furuno 's both 582's with 2 different transducers and I cant run both at once without interference...


I have the one on the bridge runing when trolling and shut it down whe I chuck and run the one in the Cockpit...

I always wondered if I should have just got a repeater screen for the Cockpit and saved the money and then they both would work with one less hole in my hull...

So it seems that I can not run both at the same time.

i think that is a great idea. i cannot imagine not having two transducers on my boat. i have two E series Raymarine, and i have the typical thru hull transducer to run those two units. however, i also installed a separate shoot thru transducer which operates at a different frequency. that is for digital depth reporting only. even today, when running behind another boat, the raymarine was picking up the bubbles of the boat in front of me, and did not get a reading. the shoot thru gave me the depth the whole time.
redundancy is essential when you fish a lot, because something always seems to go out at the wrong time...
good luck...

I can understand why two furuno units would interfere with one another but I cant see why A c or e series in my case couldent be used in conjunction with A furuno. lets here the pro's take on this subject

Check whether its possible to wire up your single transducer to both fishfinders. This should be easy if both fishfinders are made by the same manufacturer but even if they are different manufacturers there should be NMEA compatibility between them. Airmar is the OEM manufacturer for a lot of sounder manufacturers - you may want to check this out with them.

Transducers WILL interfere with each other if they are putting out the same frequency. ie if both transducers are the common 50/200khz then you will get interference. That's why it's better to have one transducer reading to two display units if at all possible. Now if you have two transducers running different frequencies ie. a 50/200khz and 28 khz, or 28/38khz, you should be all right BUT one of your display units is going to need to be able to read the lower frequency - so you need to match the display unit to the transducer. Having a 50/200 in conjunction with a 28 is not a bad idea though, because the 28 reads deep water very well.

I have had 2 for several years one on a Furono 1650 in the bridge and one on a 582 at the helm...They interfere with each other if both are running. I am having an AirMar260 installed to run the 582 at the helm and have been told it will still interfere when both are on. There is a switch that can be installed to use one transducer to run both units one at a time just throw the switch to the one you want to use. I am going with running one unit at a time with two transducers, my main reason is if something happens to one of the transducers I have a back-up alreadyt installed rather than pulling the boat to replace or repair one.

Unless you have a very large boat you will not be able to run 2 transducers, the waves they give off will interfere and cause problems. I have 2 on my boat, but one is a back up to the other. It is not a bad idea to have each dialed in for different types of fishing, maybe one offshore and one inshore, or one for trolling and one for chunking if you can get the settings how you like, but you will not be able to run both, even a narrow beam transducer will end up hitting the other transducers beam in waters over 100ft, I'm assuming you are way deeper then that.

A friend of mine has been thinking of doing the same thing...kinda. He has a Lowrance GPS / FF combo unit with a transom mnt transducer. He just bought a Furuno 585 FF and a shoot thru TD with it to hopefully get better readings. A couple of questions..

1) If he installs the Furuno and leaves the Lowrance combo unit as is, and only uses the GPS/navigation on the Lowrance, will that still interfere with the Furuno? In other words, can you basically cut the power off to the transducer only on the combo unit?

2) Also the water temp is determined by the transom mnt transducer.....any thoughts on this?

3) Any other thoughts are more than welcome!!
