Frequently Asked Questions
Is this for the sonar or the camera?
This specific knob (21-1137-64) is typically for the Camera (VS/Mission/Quest) series. The LX Sonar series often uses a slightly different knob style.
Why is it sold individually?
Many customers only lose one side. We sell them singly so you don't have to pay for a pair if you only need a specific replacement.
Does it fit the old tube (CRT) TVs?
No. The older "Tube" monitors (VS380, VS560) use a much larger mounting bolt. This is for the flat-screen LCD models only.
