Sailboat instruments, like the boats they go on are at least semi-custom products. Each installation will differ from others in capability and features. Ockam uses a modular approach to allow the greatest flexibility in capability. A professional electronics expert is usually needed to properly design, install and set up the system. • To read a description of the Ockam Instrument system, read Sections 1 & 2. • For installation, read Section 3. • Calibration? Go to Section 3 - Calibration. • Got a problem with the system? Go to Section 3 - Troubleshooting.
