Opticron Trailfinder HD 10x36 Monoculars In More Detail

Increased Magnification for Distant Detail

The 10x magnification provides greater reach compared to 8x models, making it suitable for observing distant wildlife, ridgelines or coastal views. A 36mm objective lens supports adequate light transmission for daytime field use without increasing bulk.

The fully multi-coated optical system reduces reflections across all air-to-glass surfaces, helping maintain contrast and clarity. BAK4 roof prisms ensure consistent light transmission within the 6.2° field of view, which measures 108m at 1000m.

Viewing Comfort and Eye Position

Eye relief measures 17mm, allowing comfortable use for most spectacle wearers while retaining the usable field. The 20mm eyepiece diameter provides a stable viewing position. A three-stage retractable rubber eyecup supports accurate eye alignment and reduces stray light intrusion.

The minimum focus distance of 5.3m reflects its emphasis on mid to long-range observation rather than close viewing.

Construction and Environmental Protection

The aluminium alloy body maintains rigidity while keeping weight to 288g. Full PR rubber armouring improves grip and provides light impact resistance. Nitrogen filling prevents internal fogging, and the IPX-6 rating indicates protection against heavy rain and water exposure.

At 125mm in length and 56mm in width, the monocular remains compact for pocket carry. The integrated belt clip allows attachment during walks, and compatibility with the Opticron 29030 38mm neoprene strap provides an alternative carrying option.

Intended Use

This configuration suits hikers and countryside users who prioritise reach and portability. The 10x36 format offers increased subject detail while remaining significantly lighter than carrying binoculars of similar objective size.
