If I have two sonars on the front of the boat running a humming bird and a lowrance. Does the sonars interfere with one another ? Thank you

I have 2, front and back. My humminbird (2018 helix) on the back and Lowrance (2008) on the front. I get some interference on the Lowrance, but not enough that I can't decipher what's going on (though sometimes I have to walk to the console to do a "reality check") to ensure I'm not actually missing some standing timber or something. The Humminbird seems to filter it out, but what can you expect from a 12 year old Lowrance, it's still a good 2d sonar and has amazing out-of-the-box maps.

Interference is something that I have wrestled with often over the years. I never really know if they are going to interfere until they get hooked up and try them out. More often than sonar interfering is the trolling motor interfering. The trolling motor foot pedal often has a ground that is key. I also have put rubber between the transducer and the trolling motor head. That has solved my interference problem. I have run different units many times over the years. Humminbird, Garmin, and Lowrance. I didn't have much trouble with interference.
