This is my version of an Seatalk remote control. I had a ST3000 on my old B31 sailboat. But the original control panel was located low and facing backwards witch made it difficult to adjust course and tack. This one I had mounted above the entrence hatch where the rest of my instruments was mounted. So now it was pleasent to tack or "button" steer the boat. During bad weather I could sit under the sprayhood and steer witch is quite nice. I used this version for two seasons with no problems.
One suggestion is to spend som money on box-and-button quality! Saltwater should be treated as it was acid!
