I have two of these remote spotlight controls......one for a roof mountd unit and one on the bow rail, and I'd trade them both for a good hand control like the old days. I keep a portable 12V plug in style light in the port helm cabinet cuz the operation and fine control of the remotes are so clumsy on a moving boat. Eye and hand coordination can compensate for movement but a solid mounted spot can't, and the remote lights are expensive to purchase and maintain. Both my spot lights have needed motors. Soon, they're history. They look good, but are just another maintenance item. Hand held spot units are cheap (as long as you're not buying them at a marine store)and easily replaced.....take anywhere you need light. Flood lights are another matter.
