Opticron GS 665 GA ED Spotting Scope Review

Introduced in response to demand for high quality lightweight waterproof spottingscopes the Opticron GS 665 GA ED fieldscope sets the standard for people wanting to take-out and walk-about with their spottingscope whether for birdwatching or general wildlife observation. Available in straight-through or 45°, the fieldscopes are designed and manufactured to meet the three main requirements demanded by today's active telescope user: high-end optical performance, usability and reliability.

'High end' optical performance and value 
The GS 665 GA ED fieldscope uses a 66.5mm diameter objective lens without any noticeable gain in size or weight over a 65mm. With a 5% more light entering the telescope, more light is emitted, resulting in brighter images compared to a standard 65mm model. 100% designed and manufactured in Japan using high quality glass and other materials, each GS 665 GA ED fieldscope produces high resolution images with minimal edge distortion and accurate color reproduction.

The GS 665 GA ED fieldscope is designed to provide class winning optical performance seamlessly in even pretty harsh conditions. Protected by full body natural rubber armor, the centrally positioned focusing wheel allows easy access for both right and left handed users and is rubber covered to deliver a positive feel with or without gloves. The focusing system is designed to allow adjustment from infinity to 50 yards in just a 270° turn with close focus set at 13ft. Housed within the same mechanism is a 9:1 ratio focus adjuster, providing greater focusing accuracy at top end magnifications.

More often than not, telescopes need to be tripod mounted for image stability so any weight saving is crucial. Constructed to be as light as possible, the GS 665 GA ED weighs just 37oz (w/o eyepiece) and as a result can be used comfortably on a standard ‘non fluid’ panhead often found on Clamps or Travel Tripods. In addition each unit is fitted with a -/+ 90° rotating die-cast alloy tripod sleeve with 45° incremental 'stops'. This feature enables the scope to rotate around its’ central axis for accurate positioning when mounted to a bipod or on a clamp in a Hide or Blind. To avoid problems of reflected light on the objective lens in bright sunlight models are fitted with a retractable lens hood with integrated objective lens cover.

Having access to full a range of eyepieces is also important and the GS 665 GA ED fieldscope is fully compatible with Opticron SDL and HDF T eyepieces including the 40862G HDF T 16-48x and 40809G HDF T 25xWW.

Extensively tested for continuous trouble free use in varying temperatures, the models are fully nitrogen gas filled waterproof and come with the assurance of a 20 year Premiere Plus Warranty.
