Summit's Garmin GT52/GT54/GT56 Transducer Mount is the best solution on the market to allow the simultaneous use of the Livescope and 2D transducers on the same pole.
This mount slips over the Livescope transducer mount and attaches to the pole using the same attachment pin. Which allows the use of Livescope without the 2D transducer attached depending on the circumstances. Note: The use of one of our Livescope Transducer mounts is required for use with this mount.
