I'd say you have been fortunate. 100 feet is certianly deep enough that the cones would intersect. It might be that the interference has been slight and you have just not noticed it. Did you have a noise rejection feature turned on? I would be interested in what brand and model of sonars you are using. I'd like to be able to run two units on my boat but haven't been able to without interference.
