The ForwardScan transducer can be expelled from its tempered steel sleeve for upkeep. On the other hand, new vessels might be fitted with an unfilled sleeve to permit simple on-water establishment of the ForwardScan transducer sometime in the not too distant future. The sleeve includes a self-shutting valve to limit water entrance when the transducer is first evacuated, however a blanking plug is required to give a completely watertight seal without a transducer.
- Blanking plug for the standard ForwardScan sleeve
- Provides a watertight seal while no transducer is installed
