Kev faib tawm thiab xaiv cov cuab yeej ntsuas qhov deb ntawm laser
Laser rangefinders muaj ultrasonic rangefinder, handheld laser rangefinder, laser rangefinder telescope (telescope laser rangefinder), ib qho yog los txiav txim koj qhov ntsuas ntau; qhov thib ob yog los txiav txim qhov tseeb ntawm qhov ntsuas; qhov thib peb yog siv lub sijhawm. Hauv kev yuav khoom ntawm cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau:
Ua ntej, yog tias koj tsuas yog yuav tsum ntsuas qhov kev ncua deb li ntawm ob peb metres lossis kaum kaum metres, thiab qhov yuav tsum tau muaj tsis yog siab heev: koj tuaj yeem xaiv "ultrasonic rangefinder". Vim lub ultrasonic rangefinder ntsuas los ntawm ib puag ncig, nws stability thiab directionality tshaj lub laser rangefinder pluag, tab sis nws cov nqi kuj pheej yig! Ntau haum rau kev ntsuas sab hauv tsev.
Qhov thib ob, qhov ntsuas qhov deb tsis ntev, ntau dua rau sab hauv tsev, siab precision yuav tsum: tuaj yeem xaiv "handheld laser rangefinder". Qhov no hom rangefinder nyob rau hauv tsev siv qhov zoo tshaj plaws *, nws ntsuas qhov tseeb thiab cov nyhuv yog zoo heev!
Qhov thib peb, kev ntsuas qhov ntev, ntau dua rau kev siv sab nraum zoov: koj tuaj yeem yuav "telescope laser rangefinder" (ie: laser rangefinder telescope). Ob lub telescope, thiab rangefinder; multi-fold soj ntsuam magnification, tus neeg siv tsuas yog los ntawm lub eyepiece sab hauv cross aiming system, koj tuaj yeem yooj yim tsom ntawm lub hom phiaj rau kev ntsuas kev deb. Nws tuaj yeem ntsuas qhov kev ncua deb ntawm lub hom phiaj los ntawm kev siv cov pob tshab infrared laser emission thiab txais tos uas tsis muaj teeb meem rau lub qhov muag, thiab yog compact thiab hnav.
Plaub, ntsuas qhov ntev thiab ntsuas sab nraum zoov: koj tuaj yeem xaiv kom muaj lub teeb pom kev zoo hauv lub teeb, kom koj tuaj yeem pom meej dua hauv lub teeb muaj zog. Raws li qhov yooj yim ntawm kev nplua * ntsuas.
Laser rangefinder siv ceev faj: laser rangefinder tsis tuaj yeem tsom rau tib neeg qhov muag ncaj qha ntsuas, tiv thaiv kev puas tsuaj rau tib neeg lub cev. Nyob rau tib lub sijhawm, qhov dav dav laser rangefinder tsis muaj dej tsis zoo, yog li koj yuav tsum tau them sai sai rau cov dej tsis zoo thaum siv lossis khaws cia.
Cov saum toj no yog hais txog lub laser rangefinder yuav thiab siv qee cov lus qhia kom xyuam xim rau, kev siv tshwj xeeb ntawm cov khoom siv cov lus qhia thiab phau ntawv qhia.
