| THE RANGEFINDER BINOCULARS | |
| The binoculars-rangefinder is a compact light-weight device, designed for measurement of distances, which: determines polar coordinates of objects and converts polar coordinates into square ones; determines points of view against known check reference points; observes locality and separate objects; finds their bearings on the ground . | |
|
FEATURES: Range measurement, up to 20 km The binoculars-rangefinder is supplied from storage battery. With the help of additional assemblies included in the delivery set it is possible to recharge the storage battery The apparatus may be connected to any vehicle power. Fast optics provides operation in twilight. The viewfinder graticule is illuminated, if necessary. DELIVERY SET Laser binoculars-ranger proper Tripod Goniometer Charger Protection device |
| LPR-1 is widely applicable in construction, repair and geological
survey jobs, pipeline laying (through water obstacles including); in navigation
(sea and river) when arranging navigation notices, and pilotaging in narrow
waters; when measuring flight altitude from helicopters or balloons; at
ordnance fire correction. It is equipped with goniometer which affords accurate
measurements of horizontal and magnetic azimuth, vertical angles. The binoculars-rangefinder gives additional information on an object presence in cut-off interval and more than one object on sighting line. | |
