LEI Accessories SB-5BK Transducer Switch Box (Discontinued)

LEI Accessories SB-5BK Transducer Switch Box (Discontinued) – New Old Stock

Maximize the versatility of your vintage marine electronics with the LEI Accessories SB-5BK Transducer Switch Box. This genuine, discontinued component allows boaters to connect and toggle between two separate transducers using a single sonar unit. It is an essential tool for anglers who utilize different transducer types (such as high-speed and trolling motor mounts) on the same vessel.

This item is New Old Stock (NOS). While the unit inside is unused and in factory condition, please note that the original clear blister packaging shows significant "yellowing" and shelf wear due to age.

Why This Legacy Part?
