What you are suggesting would be great if that is what they do, but they don't. If two sonar units are operating on the same frequency, and their sonar cones intersect under the water, they will interfear with each other. Some units have filters which can sometimes minimize the effects but it is not ideal. I have seen what looks like a series of fence posts standing in a row on one of my sonars. When I turned off the second unit the "fence posts" disappeared. Having two units running within "earshot" of each other is just like trying to listen to two people talk at the same time. You can get most of what is said but sometimes it gets a little confusing.[
] If you have each unit set to transmit a distinctly different frequency, like 200 khz and 50 khz, then there is no problem.
