The Opticon OPR 3201 weighs only 80 grams, much less then other pistol-style scanners on the market today. It comes equipped with a large grip with scanning parts near the central core to stabilize hand movement and minimize user fatigue while gathering codes. It features auto trigger feature. When using the OPR 3201 with the complementing stand, you initiate instant hands free scanning. When manual control is preferred the scanner can also be operated as stand-alone unit.
