Lowrance and hummingbird interference

[fishmaster13184]

Is there anyway I can run my lowrance and hummingbird at the same time on my boat? Neither one is fancy but I'd like to be able to use the bird at the stern for setting down riggers

Should be OK if the transducers are different frequencies.

[fishmaster13184]

I'm guessing they are not, the bird makes the lowrance go all loopy and give bad depth readings

[Sk8man]

Ah... probably the only way would be to  see if one or the other unit can use a transducer of  different frequency (e.g. 50khz instead of 200 or 83 etc.) if neither is dual frequency.

Tried doing the same on my boat with two Lowrance units even at two different frequencies and still had bad screens. Had to shut sonar function off on one and use it soley as a GPS.

There is your answer!

Same thing happened on my boat. I ended up running one as a dedicated gps and the other for depth.

Possible to run 2 Lowrance at different frquencies and if you got interferences you lower the sensitivity and the ping speed.

With a Lowrance and a HB it's impossible because with the Humminbird even if you choose a frequency the unit continue to emit the other one in the background.
