Frequently Asked Questions

How accurate is the temperature measurement?

The ST-02MSB provides high-precision temperature readings with ±0.3°C (±0.17°F) accuracy and a fast 5-second response time, ideal for detecting thermal boundaries and temperature changes while fishing or navigating.

Can the sensor be removed for cleaning or storage?

Yes, the retractable insert design with water valve allows you to remove the sensor for cleaning, maintenance, or winter storage without water entering the hull. This feature is essential for seasonal boat storage and sensor maintenance.

What size through-hull opening is required?

The ST-02MSB requires a standard 51mm (2-inch) through-hull opening. It can fit into existing 2-inch thru-hull installations or requires a new 2-inch hole if installing from scratch.

Will this sensor work with non-Furuno electronics?

This sensor is specifically designed with a 6-pin Furuno connector for Furuno marine electronics. While the physical sensor may function with other systems, compatibility and proper data interpretation depend on the receiving equipment's ability to process Furuno's signal format.

For over 70 years, Furuno has been continuously imagining and creating new solutions, making new marine electronic equipment with the goal of offering both performance and simplicity for everyone. Not only for men and women who make a living on the seas, but also for those who simply want to enjoy the boating lifestyle. For them, Furuno has become synonymous with quality, performance, and reliability.
