Wrist Compass for Marine Navigation

This Minn Kota marine receiver is a wrist-mounted compass built for underwater navigation. It serves divers, sailors, kayakers, and hikers who need reliable directional reference. The 5ATM waterproof rating supports submersion to 50 metres. A luminous display allows reading in low-light conditions.

Simple Bungee Mount Installation

The compass attaches via an 89 cm high-density elastic rope that adjusts to wrist, arm, or gear. The bungee cord secures the unit to wetsuits or drysuits without tools. No power supply is required, eliminating battery concerns. The ABS and plexiglass enclosure resists impact during active use.

Analog Navigation Limits

The rotating bezel provides 360-degree markings in 30-degree numbered increments with 5-degree indicator marks. A red lubber line and reciprocal index points aid heading management. Accuracy depends on the magnetic needle and user skill, not electronic sensors. The device functions in both northern and southern hemispheres.

Questions about this item

How can I verify the compass is working correctly after putting it on?

The red lubber line and 360° rotating bezel with 30° numbered increments and 5° indicator marks should rotate freely; the luminous display glows after light exposure, and the triangle arrow always points to magnetic north.

What comes in the package and is anything else required?

The box includes the compass with bungee mount, an 89 cm elastic rope, a user manual in English, and a package box; no additional items are needed for wrist or body mounting.

Which size and weight version should I choose for diving?

The single model measures 8 × 6.5 × 3.5 cm, weighs 82 g, and is rated 50 m (5ATM) waterproof, making it suitable for deep water operation.
