The M-3 8x30 B F.GA is designed and manufactured to meet the toughest performance criteria
demanded by the professional looking for a compact, wide angle 8x magnification field glass for
hand held use. Manufactured from die cast aluminium with a specially constructed aluminium alloy
hinge assembly and individual eyepiece focus, each binocular is 100% nitrogen gas filled waterproof
and individually tested to remain sealed after being submersed in 2m of water for 2 hours. This level
of integrity ensures the instrument remains waterproof under the most severe field conditions.
Featuring 8x magnification (apparent object distance 12.5m at 100m) with a wide-angle 8.2º field of
view, the M-3 8x30 has a 19mm eyerelief that delivers the full field of view with glasses or protective
eyewear. Other features include;
• ndividual Eyepiece Focusing ~ infinity to 4 metres close focus
• Fully multi-coated optical system
• Stringent QC tested optical components
• Brace mounted prism assemblies
• Durable natural rubber armouring for protection against knocks
• Fold down rubber eyecups
• Tripod adapter socket (1/4”)
• 10 year guarantee
Models supplied with rubber rainguard and integrated rubber objective lens caps.
Optional cases available (see table).
The M-3 8x30 B F.GA can be supplied with a dual
distance/size scale projected into the right hand eyepiece.
The primary scale allows you to measure in metres the
distance of a target object if the height is known, or the
height of that target object if the distance is known.
Calculating distance from an object the height
(or width) of which is known
Distance (m) = Height (m) x100 / Units on scale
Calculating the size of a target object the
distance from which is known
Size (m) = Distance (m) x Units on scale / 100
The secondary angled scale can be used to determine
approximate target distance up to 20km using a
reference object of height 2m e.g. the height of a person.
To calculate, place the target within the angled lines. The
number on the scale shows the distance in kilometres from
4 to 20km.
