Product Details
Introduced in response to growing demand for quality lightweight nitrogen waterproof telescopes and developed around an optical system featuring objective lens sizes of 66.5mm and 81.5mm, GS fieldscopes set the standard for customers wanting to take-out and walk-about with their equipment whether pursuing birdwatching or general wildlife observation.
The models are designed and manufactured to meet the three main requirements demanded by today's active fieldscope user; 'high end' optical performance and value, usability and reliability.
For optimum size & weight to performance ratios, the GS 665 GA warrants serious consideration for users choosing either zoom or fixed magnification eyepiece options.
GS Fieldscopes are protected by 'full body' natural rubber armour with a textured finish to the top half of the main body prism housing. The centrally positioned focusing wheel allows easy access for both right and left handed users and is also rubber covered - delivering a positive feel with or without gloves.
The focusing system is designed to allow adjustment from infinity to 50 metres in just a 270° turn. Housed within the same mechanism for convenience is a 9:1 ratio accurate focus adjustment.
Having access to full range of different magnification eyepieces is also important. The GS series are fully compatible with Opticron SDL, HDF & HR eyepieces including; 40862G HDF T 16-48x (665) / 20-60x (815) 40809 HDF T 25xWW (665) / 32xWW (815).
Designed to enable rotation around the main axis of the instrument for use on a bipod or in a hide with a high window, GS fieldscopes feature a solid die-cast tripod sleeve with -/+ 90 degrees each-way action with 45° incremental 'stops.'
