1. Thin-film phonic switch
2. Visible verticle laser objective
3. Ultra-short viewing distance
PLV-1A Precision Laser Plummet
Features
Thin-film phonic switch Original thin-film phonic switch design not only enhanced the water-proof feature of PTV-1A,but also convenient to master light adjusting degree.
Visible verticle laser objective Able to see clearly laser beam through telescope,no harm to eyes.effective viewing distance is 150m Infinity focus adjusting knob Orginal infinity focus adjusting design,not only able to avoid slippage phenomenon,but also could extend service life of knob
Ultra-short viewing distance 0.2m untra-short viewing distance ,able to further extending the viewing range Water-proof feature Professional water-proof design completely avoid be effected with damp,water-proof degree is IP55
