Determining the correct transducer installation angle is critical for accurate depth readings. The Airmar Deadrise Angle Finder takes the guesswork out of hull angle measurement, delivering ±½° accuracy with ball-bearing construction and a strong ceramic magnet that attaches directly to a carpenter's square or straight edge. A built-in angle and grade reference chart on the back of the unit keeps common conversions at hand without reaching for a separate reference.

Specifications:

• Accuracy: ±½°
• Ball-bearing construction for repeatable precision
• Strong ceramic magnet for secure attachment to a straight edge or framing square
• Measures boat hull deadrise angle quickly
• Handy angle and grade chart printed on the back of the unit
