Endurance ED Spotting Scopes
Edurance ED Spotting Scopes feature twist-up eye cups as standard on the zoom eyepiece. You can use the eye-cup at any position between the full up or down position, whatever is more comfortable.
Featuring a dual focus knob system. Once focusing is achieved using the large knob you can use the small 'fine tuning' knob to achieve a very sharp image.
The lens sunshade is designed to block unwanted glare and other reflections that can spoil your view and/or image.
Your spotting scope was designed so that you could use optional Wide Angle eyepieces. These eyepieces are available from Hawke and allow varying levels of fixed power, wider fields of view and othe factors.
