Will 2 echo sounders interfere with each other...?

[divelandy]

Hi

I'm looking at getting a Raymarine A57D to replace the A435i
We already have an Eagle fish finder.

The idea is that the A57D would be a backup fishfinder.

Could we use both units at the same time - to cross check?

TIA

Depends on freqs.
I have two sounders that work quite happily with each other on four different freqs.

Hmm, both the spec's say 200khz (Raymarine / Eagle)

Any idea if there is an ID or an option to stop these interfering?

You should be able to stop one in the options and only use one at a time. using both on the same freq won't work as they will interfere with one another.

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!
