NordyTrim

NordyTrim averages the roll out of the reading to show the hull's true angle. You can watch the list come off as you pump fuel.

NordyTrim turns your iPhone into a precision inclinometer for reading the state of trim on a boat.

The problem with using a phone as a level afloat is that the boat never stops moving. NordyTrim solves this by averaging hard. Alongside a responsive one-second reading it shows a heavily damped one-minute average built from three averaging stages in series. This rejects the roll of the boat far more completely than a simple average.

A twenty-minute trace scrolls down the screen so you can see whether the trim is improving as fuel or water move about.

FEATURES

• One-second and one-minute averages of the X axis, read to a hundredth of a degree • Three-stage cascaded damping that filters out roll. • Twenty-minute scrolling trace of the damped reading. • Clear LOW and HIGH markers either side of the scale, so the trimming action needed is never ambiguous. • Manual calibration you can set once ashore against a known-level reference and keep - no need to find a steady surface at sea. • Restart button to discard readings taken while the phone was being placed. • Flip the display 180° for when the camera bulge forces you to set the phone down facing away from you. • Screen stays awake, dark and uncluttered for use at the helm or in the engine room.
