Plastimo Iris 50 Hand Compass Blue With Infinity Prism Sighting For Boaters And Hikers Ultra Precise

The Plastimo Iris 50 Hand Bearing Compass in a compact puck design delivers precise navigation in a surprisingly small package. Finished in a bold blue, this handheld instrument is built for real-world use on deck, in the backcountry, or anywhere you need quick, reliable bearings.

Unique features like the Infinity prism sighting system and a high-quality elongation membrane combine to give you accurate heading information with minimal effort. With an accuracy of less than 1 degree, the Iris 50 helps you plot courses, fix bearings, and stay on track whether you’re charting a sailing leg or navigating through unfamiliar terrain.

Reading is effortless. Hold the compass between your forefingers and thumb, bring it level to your eye, and align with your nose for a stable, precise bearing. The design is readable with or without glasses, and for night-time use, a brief exposure to bright light or a flashlight makes the dial luminous for quick bearings on dark decks or trails.

Designed for harsh conditions, the Iris 50’s puck-style form is intentionally compact (dimensions: 3.3 x 1.3 inches) so you can stash it in a pocket, pack, or aboard without crowding your space. It’s ideal for sailors, kayakers, hikers, or anyone who needs dependable, on-demand directional readings from a portable instrument.

Why this matters for your navigation

In practical terms, the Iris 50 translates quick observations into reliable bearings, helping you maintain a steady course even when visibility is limited or when you’re balancing on moving decks. Its durable construction and precise optics are designed for repeatable performance in marine environments, but the compact, lightweight form also makes it a versatile tool for land-based expeditions or backcountry routes where dependable direction is essential.

Tips for best results

• When reading bearings, keep the device steady and level to your eye; small tilts can affect the bearing reading.
• For nighttime use, briefly illuminate the dial to activate the luminous feature, then read bearings with the light removed.
• Store in a dry, protective pouch to preserve the precision of the prism and membrane.
