Compatible with the following instruments:
- ST70 (direct connect to ST70 backbone, no pod required)
- Compatible hull material: aluminum and fiberglass
Hole diameter for installation: 2″
Operates at 235kHz so there is no interference with your 50/200 kHz fishfinder transducer.
Airmar’s Smart Sensors have embedded microelectronics, meaning the signal is processed from within the transducer itself, eliminating the need for an ST70 transducer pod.
