Signet Marine SL11 Knotmeter
Paddlewheel Sensor

Unique design for the purist.

The Signet Marine SL11 Analog Knot meter consists of a precision instrument and unique paddlewheel transducer to provide definitive speed indication for both racing and cruising yachts. The SL11 Analog Knot meter is capable of sensing and displaying variations in speed as low as 0.1 knot!

The Signet Marine SL11 Analog Knot meter is completely self-powered. This makes it ideal for smaller yachts with limited power supplies or as a backup unit for larger yachts. The transducer generates an AC signal which is read by the dampened meter movement. For night use, red illumination is provided through a full 360-degree lens (12V power required).

The SL11 Analog Knot meter comes complete with all mounting hardware and your choice of through-hull fitting.

The instrument was designed to provide you with many years of trouble-free service. Its transducer is compatible with Signet Marine through-hulls dating back over 40 years, making it the perfect upgrade for your current knot meter.

Each unit is vigorously tested and must pass extensive quality control standards before it is shipped. All units come with a two-year warranty.
