LRM 3500CI Product Features: A customer has choice of several factory preset menus. The unit will operate in accordance with customer’s expressed preferences.Main features are: Angular measurements: mils, degrees. Distance measurements: meters, yards Speed measurements: KMH, MPH Digital output: RS-232 or Bluetooth GPS compatibility: Protocol level or built-in Gating capability: 100 meters step. First, last and automatic target acquisition. LRM 3500CI combines excellent optics with the latest advanced technology. Revised approaches in optical and electronic engineering that incorporate many years in development of laser range finding technology allow target acquisition at longer distances with better reliability under wider ranges of weather conditions. This model allows you to observe distant objects with great image quality plus it measures distance to the object (up to 3.5 kilometers), its elevation, azimuth and speed - all in one. Aim and click - and you know all what you want about your target. Computer output allows immediate data acquisition by any system with standard RS-232 interface, including various GPS models. The device has gating capability and variable logic of target selection.     Specifications Magnification Objective lens Field of view Diopter adjustment range Range finder Laser type Measuring distance range Measuring azimuth range Measuring elevation range Distance accuracy, m Azimuth and elevation accuracy Distance resolution Measurement time, sec First / last/ Auto logic Gating capability, m Gating step, m Meter / Yards display Computer output Last 10 reading recall Reticle shape selection (+ or []) GPS (optional) Scan mode Speed detector Miscellaneous Power supply Battery capacity, shots Low battery indicator Rubber armour Water resistant design Tripod socket Dimensions, mm Weight, g   7x 25 8° ±4 905 mm class 1 eye safe 1-3500 6,400 mils / 360 ±60° ±1 ±1° 1 0.5 V 100-3500 100 V RS232 V V V V V 9V Lithium non-magnetic >5000 V V V 1/4" 127x125x60 460
