When one Digi-Troll&trade unit is connected to a Digi-Troll™ transducer, other units can be interphased with the master unit using this relay interphase cable. This allows all Digi-Troll™ units connected to the master unit to independently operate the bottom tracking feature, while only using one transducer.
