Topcon RL-HV2S Single Grade Laser
W-9 and vendor pack with every quote
Shipped direct from the manufacturer
Topcon classifies the RL-HV2S a Multi-Purpose Construction Laser, doing horizontal, single slope, dual slope and vertical work in either the X or Y axis, and the price includes a laser receiver, the LS-80X or the LS-100D depending on which option you pick.
01
Topcon classifies this a multi-purpose laser that does dual slope and vertical work, not a single-slope-only unit
Topcon's own spec sheet calls this a Multi-Purpose Construction Laser, dual-slope capable, built for horizontal, single slope, dual slope or vertical layout in either axis. Topcon's own model catalog confirms the grade type as Dual, in a table that lists the true single-axis sibling model, the RL-HV1S, as Single. That sibling works X-axis slope only, with no vertical dual-axis mode; the two share a family name and a similar case. If your job needs dual-slope grading or a vertical layout on either axis, this is the model built for it. Self-leveling runs plus or minus 5 degrees on both planes, and rotation speed switches between 300 and 600 rpm.
02
The price bundles a laser receiver into the box, the LS-80X or the LS-100D depending on which option you buy
Two versions of this listing exist, and each bundles a matching laser receiver, the handheld sensor that reads how far above or below grade the beam sits. Pick the LS-80X option and you get the LS-80X receiver paired with alkaline dry-cell power. Pick the LS-100D option and you get the LS-100D receiver paired with a rechargeable battery pack instead. The LS-80X switches between normal precision, plus or minus 2.0 mm, and high precision, plus or minus 1.0 mm. It reads to about 800 m of working diameter on its own, and carries an IP66 dust and water rating. It shows grade on a dual display, front and back, and runs roughly 120 hours on two AA batteries. No independent Topcon specification document exists yet for the LS-100D receiver on its own, so its precision and range are not stated here.
03
The 800 meter range is real, but Topcon ties it to 600 rpm and the LS-80X receiver specifically
Topcon states a working range of approximately 2 to 800 m, about 6.5 to 2,600 feet, as a diameter. That figure is measured at 600 rpm and with the LS-80X receiver; a different speed or receiver is not guaranteed to hold it. The same brochure restates the identical circle elsewhere as a radius of over 400 m, about 1,300 feet. That is the same distance described the other way round, not a second, larger range. No Topcon document, and neither dealer page checked, states whether the LS-100D pairing reaches the same 800 m figure. Call and ask before you order if your site needs that guarantee.
04
Topcon's own manual and its own brochure state two different grade ranges, and neither is corrected here
Topcon's operator's manual, in its specifications chapter, states the grade setting range as plus or minus 15 percent on both the X and Y axis. No base-percentage qualifier appears anywhere in its text. Topcon's own brochure for this same model states a lower base range instead, up to plus or minus 5 percent. That range extends to plus or minus 15 percent only with a tilting plate accessory. Both documents are Topcon's own, and they disagree; we are printing both figures rather than picking the one that reads better. If your project's tolerance depends on which is correct, that is a question worth a call before you order, not after.
05
A free phone app replaces the remote, per two Topcon documents; a third calls a remote included
The free Laser Manager app, for iOS and Android, connects to the laser over Bluetooth to adjust slope and check calibration, at no license cost. Both this model's own brochure and the operator's manual's product outline describe that app as the control method. Neither says a special physical remote control is needed. Topcon's own printed catalog, a separate document, lists included remote control as a headline feature for this model line instead. We are not resolving that disagreement here; both are Topcon's own words. Bluetooth's usable range runs 100 m horizontal and 20 m vertical, under Topcon's own stated good conditions. Those conditions are instrument height above 1.2 m, no obstructing structures nearby, minimal radio interference, and no rain. Bluetooth may not be built in at all, depending on the telecommunications regulations where the instrument is purchased.
06
Battery choice changes runtime, charge time and weight; the warranty term stays five years either way
Run it on four D-size alkaline batteries and Topcon rates the laser for about 120 hours at 20 degrees C. Run it on the rechargeable BT-79Q pack instead and that drops to about 65 hours, with a charge time of roughly 13 hours through the AD-15E converter. Weight shifts with the battery too: about 2.6 kg, 5.7 lb, with dry batteries fitted, about 2.8 kg, 6.2 lb, with the BT-79Q pack fitted instead. The instrument is IP66 rated for dust and water, and runs from minus 20 to 50 degrees C. It is a Class 1 laser, 635 nm visible red, 2.4 mW. Never point the beam at another person: it is injurious to the eyes and skin, and an eye injury needs immediate attention from a licensed ophthalmologist. Topcon backs the instrument with a five-year warranty, whichever battery or receiver option you choose.
07 FOR UNIVERSITIES, COLLEGES AND GOVERNMENT AGENCIES
Two SKUs ship direct from Topcon; call before you order and we confirm what is in the box
This listing covers two SKUs, the w/LS-80X package and the w/LS-100D package, and every unit ships direct from Topcon. My Surveying Direct is an authorized reseller. Confirmed across more than one independent source: the laser unit, the receiver matching the option you buy, and a carrying case. Not confirmed: batteries. Topcon's own manufacturer page states that its products generally ship without alkaline batteries, for shipping reasons, and tells buyers to source the correct type locally. This model's own brochure, though, lists batteries among the kit's components, and neither of the two dealers we checked names batteries as included either. Those same two dealers disagree with each other on a separate point: whether a printed manual ships in the box. We are not printing a packing list we cannot stand behind. Call +1 888 850 6533, Monday to Friday, 9 to 5 Mountain Time, and we will confirm exactly what ships in your box, batteries included, before you buy.
