What customers say
Customers overwhelmingly value the Raystar 150 for its superior reliability and performance. Users consistently report exceptionally fast satellite acquisition, crediting the dual GPS and GLONASS capability for precise positioning even near obstructions. Integration is simple, often described as plug and play with existing SeaTalkng networks. The robust, marine-grade build quality inspires confidence in its long-term durability against harsh weather. While this unit represents a premium investment, serious navigators agree that the enhanced accuracy and foundational dependability it offers fully justify the cost, making it an essential upgrade for modern marine electronics.
Know before you buy
Yes, the RS150 is fully compatible with NMEA 2000 networks. It includes a SeaTalkng spur cable, which can be easily adapted to a standard NMEA 2000 backbone using a DeviceNet adapter cable.
Yes, the unit is designed for surface mounting out of the box, but it is also compatible with standard marine pole mounts. You will need to purchase the optional pole-mount accessory separately to complete that installation.
A 10Hz update rate means the sensor calculates your position ten times per second. This provides much smoother, more responsive tracking on your chartplotter screen, which is particularly helpful when navigating at higher speeds or in tight channels.
The RS150 supports multiple satellite constellations, including GLONASS and SBAS (such as WAAS and EGNOS). This multi-constellation support significantly improves signal reliability and accuracy in areas where standard GPS signals might be obstructed.
Yes, it carries an IPX6/7 waterproof rating, meaning it is built to withstand heavy spray and temporary immersion. It is fully designed for the harsh marine environment.
No, the RS150 is powered directly through the SeaTalkng or NMEA 2000 network backbone. It has a very low power draw of 30mA, so it will not put a significant strain on your vessel's electrical system.
