Precise and useful companion on the water, at regattas, but also during hiking and trekking. Handily large and weighing only 90 g, courses can be determined very precisely in a 30° field of view. An infinitely adjustable memory ring allows you to record the last measurement, plus red lubricating lines and a photoluminescent scale. The measuring scale is fluid damped for even more accurate reading. Shockproof, waterproof and sandproof.
