I am no "spider rigger" BUT if you mount ANY type unit on the TM, your baits are already well past any structure that shows up WHEN it shows up. If that is going to be your primary technique, I do not see the benefit of a TM mounted sonar. Am I missing something? The only way that I could see that a front mounted sonar would be useful for SR'ing would be to mount an SI transducer on some sort of articulating mount, set it to scan from one side and then "sweep" the beam from side to side so that it showed cover in the boats path.
