Control your autopilot even when you're below deck and away from your autopilot. Raymarine offers two new add-on wireless remotes compatible with many Raymarine SeaTalk base autopilot systems. The intuitive menu structure allows for easy operation and to easily access features. Take full on-board control with the Smart Controller that uses two rechargeable NiMH batteries (included) and on average operates for two weeks from a single charge! The wireless ST100 gives you basic, on-board control and operates on two "AAA" alkaline batteries (not included). Both have a lightweight and compact design for easy handling. Two-year warranty.
