77mm XD Lens
|
|
|
|
The PROMINAR models “TSN-773/774” have an XD objective lens with low dispersion properties to diminish chromatic aberration. Like the TSN-880 Prominar models, the concave lens paired with the XD lens is made of glass with special dispersion properties to reduce the chromatic aberration to a further degree. The performance and compactness of these spotting scopes are second to no other scope in this class.

Advanced DesignAdvanced Design-This body, designed to be user-friendly, is light and compact despite its large objective lens and metal construction.
|
|
|
Compact SizeThe adoption of the inner focus system keeps the prism box light and compact, realizing a large 77mm objective lens in a body length of a 60mm class scope.
|
||
Magnesium Alloy Body

 |
|
|
The magnesium alloy body decreases the weight of the scope while providing a rugged structure that can withstand the severest conditions.
|
||

|
||
Eyepiece Locking Mechanism
|
 |
|
|
The eyepiece locking mechanism secures the eyepiece to the scope body and prevents it from getting lost or falling off suddenly.
|
||
Tripod Mount
|
 |
|
|
The addition of a brass insert to the tripod mount of the scope allows the scope to be secured to both 1/4 and 3/8 inch mount tripods.
|
||
