Delta Optical Delta-T 9x45.HD.RF binoculars with laser rangefinder

The Delta-T model comes with a laser rangefinder that can measure distances of up to 2377 m, enabling precise assessment of distance, inclination angle, height variation, and equivalent horizontal range (EHR). The 45 mm objective lens and fixed 9x zoom facilitate observing under varied lighting conditions. Its nitrogen-purged, sealed construction offers protection from water, moisture, dust, and dirt.

The rangefinder's information is displayed on an OLED screen with a 5-level brightness option. Two buttons on the binoculars' upper surface and a short measurement duration make for quick and straightforward operation. Additionally, the rangefinder measures tilt angles (from -70 to +70 degrees, accurate to ± 1 degree), height differences, as well as equivalent and horizontal distances (EHR). Powered by a CR2 (3V) battery, it allows up to 3,000 measurements, and the Auto off feature conserves power by switching off the device after 10 seconds of inactivity.

The Roof prism system in the binoculars provides a more expansive field of view. Fully Multi Coated (FMC) anti-reflective layers reduce glare from the lens surface. HD fluorite glass lenses significantly cut chromatic aberrations for crisp, high-contrast images that deliver precise color fidelity and exceptional quality across the viewing area.

The measurement capabilities depend on the object size during distance assessment:
- single-family house - 1828 m,
- animal - 750 m.

Constructed from a robust magnesium alloy, the binoculars' body is coated in rubber, enhancing grip stability and softening impacts and drops from low heights. The eyecups, made from soft rubber, offer comfort during use. With an IPX7 waterproof rating, it is water-resistant and can be submerged in water for up to 30 minutes to a depth of 1 meter.

Focus can be fine-tuned using a central adjustment knob. Each eyepiece has independent dioptric correction within a ±4 range. The eyepiece spacing is adjustable for a personalized fit. A 1/4" thread allows attachment of a tripod adapter.

The set includes:
- Delta-T 9x45.HD.RF binoculars,
- case,
- strap for the case,
- strap for wearing around the neck,
