Any idea if there is an ID or an option to stop these interfering?
Your frequency comes from the transducer the unit interprets its, you will therefore need to make sure your units are shipped with dual frequency transducers usually 50KHz and 200KHz or specify single frequencies, one 50 and one 200. Rig/Choose options to run one unit on 50 and one on 200 or vice versa and you'll be ok. Divers might like that as you'd see more bottom on the 50 but have more detail on the 200. I'm always for more bottom!
