"A brilliant all-rounder for stalking and general observation. The Forest Gen 3 10x42 offers crisp, bright images with excellent colour fidelity, even in challenging light.

The Delta Optical Forest 10x42 Gen3 Binoculars combine a lighter, more refined design with an enhanced optical system to deliver exceptional clarity and reliability in the field.
As the third generation of the popular Forest series, this model has been engineered for experienced observers who demand high performance, durability, and precision in all conditions.
Equipped with ED (Extra-Low Dispersion) glass and BaK4 roof prisms featuring dielectric and phase-correction coatings, the Forest 10x42 Gen3 produces remarkably sharp, high-contrast images with vivid, natural colours.
Fully Broadband Multi-Coated (FBMC) lenses maximise light transmission, offering bright, detailed visuals even at dawn or dusk.
The robust magnesium-aluminium alloy chassis, wrapped in a rubberised ergonomic armour, ensures a secure grip and lasting comfort.
Completely waterproof and nitrogen-filled, these binoculars are resistant to fog and moisture, making them ideal for demanding field conditions.
With 10x magnification and a wide 6.5° field of view, the Forest 10x42 Gen3 strikes the perfect balance between magnifying distant details and maintaining situational awareness , perfect for wildlife observation, birdwatching, and travel.
Great for:
-
Birdwatchers seeking crisp detail and steady tracking of fast motion.

Q: What viewing experience will 10×42 deliver vs other formats?
10×42 hits a sweet spot — good enough magnification to spot distant wildlife details without excessive shake, while maintaining decent brightness and field of view. A wider field of view helps follow movement easily.
Tip: Use a tripod or bean bag at 10× for prolonged sessions — it greatly reduces hand jitter.
Q: How does ED glass help in real use?
ED glass minimises colour fringing around high-contrast edges (like branches against sky), making images crisper and more natural — especially useful for birdwatchers and nature observers.
Q: Are these binoculars good in low light?
Yes — multi-coated optics and ED glass help retain brightness in dawn/dusk conditions. But remember that lower magnification (8×) or larger objectives (50 mm) will be better in very weak light.
Tip: Steady support (tripod or sling) improves low-light comfort when your hands fatigue.
Q: Can people who wear glasses use these comfortably?
Yes — with about 15 mm eye relief, these work reasonably well with glasses. Twist-up eyecups help fine-tune position for optimal view.
Q: How do I care for them in the field?
Keep lenses clean with a soft microfiber cloth (included), avoid direct pressure on lenses, and store in the case when not in use. Moisture-resistant housing helps, but drying after wet use keeps optics clear.
Q: What’s the benefit of tripod compatibility?
At 10×, extended viewing sessions (e.g., scanning ridgelines or watching flocks) benefit significantly from tripod stability — especially important in low light or shaded terrain.
