Optical performance is excellent, with all models delivering crisp, bright, sharp, high-resolution images, across the entire field of view. The objective lenses are multi-coated for maximum light transmission and image contrast.
A Zoom eyepiece is included with each model as standard, but other interchangeable fixed magnification eyepieces are available separately. Focusing is ultra-smooth and practically eliminates vibration whilst in use.
The tubes are covered with a protective rubberized paint finish to help protect from the elements. All models can be mounted on a standard photographic tripod via a ¼" tripod bush. Supplied with carrying case.
Acuter waterproof fieldscopes are O-ring sealed and nitrogen purged providing waterproof, fogproof, and dustproof protection.
