I have sold six Humminbird SONAR units with side imaging. We have installed each one and have only used the transducer that came in the box with the unit. Each unit operates very well with only the single transducer.When we were installing the most recently sold unit, the question of adding a second transducer for high speed operation came up for the first time. I talked with my Humminbird rep about this new question. He said that some installations now are getting a second transducer for high speed operation. The thought behind the second transducer is that the side imaging transducer is rather large and on some boats throws a large amount of spray, usually all over the engine. When this occurs, the side imaging transducer can be mounted above the bottom of the boat as it only needs to contact the water at speeds below 6 miles per hour, and a high speed transducer can then be mounted in a standard fashion. This change also requires a splitter and a switch for the user to manually control which transducer is connected to the head.
I guess we have been lucky and had no complaints about spray.
I have two customers waiting for the Lowrance Structure Scan LSS-1 units to arrive. I believe that both will be getting the Lowrance units by next spring.
