Airmar Deadrise Angle Finder - Accuracy of ± 1/2°

The Airmar Deadrise Angle Finder is a precision instrument purpose-built for anglers, boat builders, and marine technicians who need to measure hull deadrise angles with professional accuracy. Whether you're rigging a new boat, diagnosing hull performance issues, or fine-tuning transducer installation, this compact tool eliminates guesswork and reduces the time spent on angle calculations. Anglers and boaters who demand reliability on the water know that proper hull geometry directly affects boat handling, fuel efficiency, and how your vessel performs in rough conditions.

Built with a strong ceramic magnet, the Airmar Deadrise Angle Finder attaches seamlessly to a carpenter's square or straight edge, allowing you to read deadrise angles with precision accuracy of ±1/2°. This level of tolerance is critical in marine applications where even a single degree of variation can affect water flow over the hull, transducer performance, and structural integrity. The magnetic base ensures secure attachment to metal surfaces, while the compact 5 x 2 x 8-inch dimensions make it easy to stow in your tackle box, toolbag, or boat maintenance kit without taking up valuable space.

Serious boaters, marine surveyors, and professional boat technicians rely on this tool for everything from hull assessment to transducer mounting verification. If you're upgrading electronics, evaluating a used boat, or building a custom rig, accurate deadrise measurement ensures your sonar, GPS, and other systems perform at peak efficiency. The Airmar Deadrise Angle Finder integrates with standard carpenter's squares and straight edges—tools already in most marine shops and serious boater toolkits—making it an essential addition to any on-water maintenance routine.
