Clipper Duet with Electromagnetic 3 Log transducer
The best selling combined Speed/Distance Log and Echo Sounder in standard 110mm square size. Suitable for open cockpit mounting.
The Clipper Duet is supplied complete with the solid state electromagnetic speed transducer (for installation on most types of GRP hulls) and in hull depth transducer. Supplied with the EML-3 electromagnetic transducer, the log measures the boat speed through the water with no moving parts. Robust and accurate, the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water. With excellent linearity and a resolution of 0.1 Knot, over the range 0.2 to 40 Knots, the control box converts the sensor signal to a pulse output to connect to the Clipper Duet display.

Electromagnetic Log 2 (transducer and data box)
Electromagnetic Log – speed through water – with no moving parts!
The EML-2 electromagnetic speed log measures the boat speed through the water with no moving parts.
Robust and accurate, the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water.
With excellent linearity and a resolution of 0.1 Knot, over the range 0.2 to 40 Knots, the control box converts the sensor signal to boat speed, trip and total distance and sends it to any compatible NMEA-0183 display.
For a complete solution the EML-2 electromagnetic transducer and controller can be supplied together with either a
or a
or to a
NMEA 2000 backbone via our converter
EML -3 is a pulse output version of the Electromagnetic Log to suit any previous NASA Marine paddlewheel log including all Target, Clipper Logs and Duet. Also works with Raymarine ST60 Log display.

Electromagnetic Log 3 (transducer and data box)
Electromagnetic Log – speed through water – with no moving parts! It will replace most conventional paddle wheels from all manufacturers!
The EML-3 electromagnetic speed log measures the boat speed through the water with no moving parts.
Robust and accurate, the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water. This signal is converted to a pulse stream to replace any existing paddle wheel sensor.
With excellent linearity and a resolution of 0.1 Knot, over the range 0.2 to 40 Knots, the control box converts the sensor signal to a pulse output to connect to any NASA Marine paddle wheel log display (Clipper Duet, Clipper Log, Target Log, Stingray Log)
Technical Info
Pulsed output to replace exsiting paddle wheel unit
Pulses per nautical mile adjustable from 15000 to 25000 PPM
Output levels – High 5V P to P
Low 0.5V P to P
(note – the transducer is a low profile unit, the 50mm OD skin fitting included
will need to be fitted in place of your current fitting)
(NOTE – NOT SUITABLE FOR METAL HULLS)

Clipper Electromagnetic 2 Speed Log
The Clipper electromagnetic speed log measures the boat speed through the water with no moving parts.
Robust and accurate, the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water. It is designed for installation into most types of GRP hulls.
With excellent linearity and a resolution of 0.1 Knot, over the range 0.2 to 40 Knots, the log sensor sends signals to a control box which then converts the sensor signal to boat speed, trip and total distance. This data is transmitted in NMEA 0183 format to a Clipper EM Log display unit.
(NOTE – NOT SUITABLE FOR METAL HULLS)

Target Electromagnetic Speed Log
The Target electromagnetic speed log measures the boat speed through the water with no moving parts.
Robust and accurate, the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water. It is designed for installation into most types of GRP hulls.
With excellent linearity and a resolution of 0.1 Knot, over the range 0.2 to 40 Knots, the log sensor sends signals to a control box which then converts the sensor signal to boat speed, trip and total distance. This data is transmitted in NMEA 0183 format to a new Target EM Log display unit.

Cruiser Speed & Distance Log
Contemporary Design
The Cruiser Log is simple and reliable showing speed in knots, trip distance to 999 nautical miles and total distance run up to 999 nautical miles.
It is supplied with a through hull paddle wheel unit designed for installation on most GRP type hulls, weather cover and blanking cap.

Target Speed & Distance Log
All instruments in the Target Range come complete with sensors or transducers as appropriate and all necessary fittings. They are designed to run on 12v supply, but due to the very low power consumption there is no reason why they cannot run off dry batteries. They provides accurate readings for owners of sailing craft and powerboats alike. Following the NASA design philosophy, the Target Log is simple and reliable showing speed in knots, trip distance to 999 nautical miles and total distance run up to 999 nautical miles.
The Target Log is supplied with a through hull paddle wheel unit designed for installation on most GRP type hulls.

NMEA 0183 to NMEA 2000 SPEED LOG Compliant converter
The product consists of a translator box which inputs the NMEA 0183 speed log data sentences VHW + VLW. It translates the 0183 data into NMEA 2000 compliant speed and distance data for connection via a ‘micro-c’ connector directly into an existing NMEA 2000 network.
