Proster Lensatic Sighting Compass with Clinometer, ArmyGreen, Metal Body IP65 Waterproof, Luminous Dial

Proster Lensatic Sighting Compass is a rugged metal navigation tool with a sighting optic and built-in clinometer, designed for accurate bearings in all weather.

Built for outdoor navigation, the Proster Lensatic combines a traditional lensatic sighting system with a floating 360° dial, luminous markings, and an IP65 waterproof rating. Weighing approximately 330 grams, its metal construction and foldable lid protect the mechanism while an adjustable prism lens and vertical lubber line sharpen accuracy. The integrated clinometer lets you estimate slopes and heights, and the included carry bag keeps it secure on trails and fieldwork.

How does the sighting system improve directional accuracy?

The lensatic sight uses a small prism and vertical lubber line so you can align distant landmarks precisely with the compass bearing. This reduces parallax and gives a clear, repeatable reference when transferring a bearing to a map or following a direction across terrain.

• Adjustable prism lens for clearer reading at varied distances
• Vertical lubber line paired with sighting notch for exact alignment
• Foldable metal lid acts as a sighting shield and protection
• Floating dial minimizes friction for faster, stable readings

Can I use it at night or in low light conditions?

Yes — the compass card and magnet arrow have luminous elements that absorb daylight and glow in dark conditions. While not a substitute for a light source, the glow helps maintain course headings temporarily without power.

• Luminous compass card and magnet arrow for after-dark orientation
• Requires prior exposure to sunlight to charge the luminous paint
• Complement with a headlamp for prolonged or very dark use
• Protective lid reduces accidental light leakage and damage

What does the clinometer measure and how is it useful?

The integrated clinometer provides simple angle measurements so you can estimate slope steepness or approximate vertical height of objects. This is helpful for route planning on hikes, assessing avalanche terrain, or performing basic field surveying tasks.

• Measures incline angles for slope assessment and planning
• Useful for estimating tree or cliff heights with trigonometry
• Quick checks for safe ascent and descent angles while hiking
• Combined with the compass for directional and gradient decisions

How durable and weatherproof is the compass for outdoor use?

The Proster compass is built from metal with a foldable protective lid and meets IP65 dust/water protection standards. That means it resists dust ingress and can handle water spray, making it suitable for wet and rugged environments — though it’s not intended for prolonged submersion.

• Metal casing and lid protect the mechanism from knocks and drops
• IP65 rating resists dust and water spray for harsh outdoor use
• Floating, shock-resistant dial tolerates vibration and movement
• Includes a dedicated carry bag for storage and transport

Who is this for? The Proster Lensatic Sighting Compass suits hikers, campers, climbers, boaters, field geologists, and survivalists who need a robust navigation instrument with both precise sighting and slope-measurement capability. It’s ideal for anyone who prefers mechanical navigation tools over electronic devices, works in variable weather, or requires a compact clinometer alongside a traditional compass. Pair it with a map and basic navigation skills for reliable, battery-free orientation on trails, expeditions, and fieldwork.
