Delta Optical Chase 10x42 ED binoculars
The Delta Optical Chase 10x42 ED is built for people who actually use their binoculars - full days in the field, in any weather, from early morning to dusk. It combines 10x magnification, ED optics, and a compact body weighing just 730 g. The result is a pair of binoculars that fits in any backpack and delivers enough detail to make 8x models feel approximate.
ED optics - sharp edges, true colours
The Chase series optical system is built around ED low-dispersion glass, which significantly reduces chromatic aberration. In practice, this means sharp edges without colour fringing - even when watching birds against a bright sky or wildlife at a sunlit forest edge.
The field of view is 112 m at 1,000 m - well above average for 10x magnification. The image stays sharp almost to the edge of the frame, which you will appreciate quickly when tracking a moving subject.
Rugged and ready for any conditions
The body is made from lightweight aluminium with a roof prism optical system and internal focusing. The minimum focusing distance is 2 m, so the Chase handles close-range observation with ease.
The waterproof, nitrogen-filled body protects the optics from moisture and internal fogging - no matter what the weather throws at you.
Comfortable to hold all day
The modern ergonomic design is not just about looks. The body shape gives a secure, comfortable grip during extended observation sessions, when hand shake starts to matter. Despite the relatively high magnification, the Chase 10x42 ED remains a practical choice for all-day use.
Who is it for?
The Delta Optical Chase 10x42 ED is a strong choice for hikers, birdwatchers, and hunters who want detailed, colour-accurate images without making big compromises on weight or size.
