You told us you wanted the best of both worlds — so we built it. We paired Topcon’s professional contractor-grade dual-slope laser with the best receiver on the market to give you a hybrid mix of Topcon precision and Spectra performance in a single kit. No compromises. No upselling. Just the premium setup serious contractors have always wanted.
This is a Contractors‑Tools.com exclusive build — engineered for the contractor who refuses to settle. When only the best will do, this is the kit you order.
Why This Kit? The Best Laser Deserves the Best Receiver.
The Topcon RL-HV2S is one of the finest dual-slope rotary lasers on the market — long range, Bluetooth-controlled, built like a tank. But here’s what most contractors don’t know: even Topcon’s best receiver can’t match the Spectra Precision HL760. That’s why we built this HYBRID kit — pairing Topcon’s proven laser engine with the best receiver in the industry.
What Makes the HL760 the Best Receiver on the Market
Massive 5-Inch Capture Height
The largest reception window in its class. Spend less time hunting for the beam and more time getting work done — on every shot.
Full Rubber Armor
Wrapped edge-to-edge in heavy-duty rubber. Drops, bumps, and rough jobsite handling are no problem. This receiver is built to take it.
Smart Fractional Readout
The digital display shows you exactly where you are relative to grade — in fractional inches — right on screen. No guessing. You know your elevation instantly.
IP67 Fully Waterproof & Dustproof
Submerged, soaked, or caked in dust — the HL760 keeps working. It actually exceeds the IP66 rating on the laser itself.
3-Year “No Excuses” Warranty — Best in Class
Spectra backs the HL760 with a 3-year warranty — longer than any other receiver manufacturer in this category. When a company stands behind its product like that, you know it’s built to last.
This isn’t just a laser kit — it’s a precision system upgrade. You’re getting Topcon’s best dual-slope laser and the industry’s best receiver in one complete package. Serious contractors don’t settle. Neither should your equipment.

Questions We Actually Get
Topcon RL-HV2S — Straight Answers
Every figure below comes from Topcon's own RL-HV instruction manual, which we
host on this page. If your question is not here, call 1-877-866-5721 and ask
somebody who sets these up on a jobsite.
What is the RL-HV2S, and what makes it dual slope?
A self-levelling rotating laser that can hold a grade on two axes at once - X and Y. In normal use each axis gives you up to ±5%, so you can pitch a parking lot to drain in two directions, or a pad with a crossfall, without moving the laser. The single slope RL-HV1S does X only.
Why does this kit come with a Spectra HL760 instead of a Topcon receiver?
It is our HYBRID kit: the Topcon RL-HV2S laser paired with the Spectra Precision HL760, the deluxe receiver we think is the best on the market. Any rotating laser works with any receiver, so you get Topcon's laser and Spectra's flagship receiver in one package, built and supported by Contractors-Tools.com.
What does the HL760 receiver do that a standard receiver does not?
It has a 5-inch reception height, so it finds the beam fast, and a digital readout that shows exactly how far you are from grade in mm, cm, feet, inches or fractional inches. It has six on-grade sensitivities, from Ultra fine (about 1/32 inch) to Coarse (about 1/2 inch), plus a Calibration setting (about 1/64 inch).
How long does the HL760 run, and is it waterproof?
About 60 hours or more on 2 AA batteries, with auto shut-off at 20 minutes or 24 hours. It is IP67 dust and waterproof, works from -4°F to 122°F and weighs 13.1 oz.
What warranty comes with this kit?
Topcon backs the RL-HV2S laser for 5 years, and Spectra backs the HL760 receiver for 3 years with their “No Excuses” warranty.
What grade range can I set on each axis?
Plan on ±5% on the X axis and ±5% on the Y axis with the laser set up normally on a level tripod. Cheat the tripod legs and either axis goes up to ±15%, one axis at a time - not X and Y together (see the next question). Set grade from the front panel (no number keypad, so it takes a lot of button pushes) or from the Laser Manager app, where you type the X and Y grade on your phone's number pad and press Set. Flat work is just 0.000% on both.
How much slope can I really get - is it 5% or 15%?
5% is the real number. Set up normally on a level tripod, the RL-HV gives you ±5% on an axis, and past that the laser shows rAnGE OVEr. With the legs cheated you can go up to ±15% - on the RL-HV2S that is X or Y, one axis at a time (not both at once); on the RL-HV1S, the X axis. You only get past 5% by cheating the tripod legs - tilting them so the head leans uphill toward the slope, which keeps the grade inside the self-levelling range. Two things to know before you do it: you lose Height Alert on that setup, so the laser will not warn you if it gets bumped, and you should re-check the beam against a known point more often. If your job is steeper than 5%, call us at 1-877-866-5721 and we will talk it through.
How accurate is it, and how far will it reach?
Topcon rates the RL-HV at ±10 arc seconds on both the horizontal and vertical axes. Working range is approximately 2 to 800 m in diameter (6½ to 2,625 ft) at 600 rpm, as measured by Topcon with the LS-80X level sensor. That range is the laser's; it is the figure to plan the job around.
How fast does it rotate, and which speed should I use?
Two speeds, 300 and 600 rpm, selectable from the laser or the Laser Manager app. 600 rpm is the speed the 800 m range is quoted at and the one to use when a receiver is on a machine or you are watching a display. 300 rpm is there when you want it.
How far out of level can I set it up?
It self-levels automatically within ±5° on both axes - horizontal and vertical. If it is set up beyond that, it will not level.
Can I use it vertically for alignment and plumb work?
Yes. Turn it on its side and it self-levels in the vertical plane, also within ±5°. In vertical rotation, Line Control moves the beam left or right on the X axis, ±5°, so you can walk it onto a reference point without moving the tripod.
What is Matching Mode?
Matching Mode, also called Manual Slope, lets you match the laser to a grade that already exists - a slab, a road, a pipe run. You set the receiver on the existing surface, then use the arrow buttons to lean the beam until it lands on the receiver, so the laser matches what is actually there instead of you calculating a percentage. The manual slope range is ±5° when the laser is on a level surface. It can also be run from the Laser Manager app.
What is Masking?
Masking switches the beam off in the directions you do not need - toward traffic, toward a neighbouring site, toward people - so the laser only turns where the work is. You set it from the menu with the arrow buttons.
What does Height Alert do?
If the laser is knocked or its height changes sharply, Height Alert stops self-levelling and tells you instead of carrying on working off a displaced instrument. It becomes active 10 minutes after levelling and can be switched on or off in the menu. It does not operate while you are setting dual-axis grade in Matching Mode or Manual Mode.
Can I control it from my phone?
Yes. The Laser Manager app for iOS and Android connects over Bluetooth 5.0 and lets you control the laser from your phone - setting slope from the app takes far fewer button pushes. The laser's control panel has no number keypad, so you step to your grade with the arrow buttons; in the app you type the X and Y grade on your phone's number pad and press Set. The app also runs Matching Mode, manual line control, masking and rotation speed, and switches Manual Mode, Sleep Mode and the Safety Lock. Bluetooth range is 100 m horizontal and 20 m with the laser on its side, in good conditions. Topcon's Laser Manager quick guide is on this page to download.
How long do the batteries last?
On four D-cell alkalines, 120 hours. On the rechargeable BT-79Q NiMH pack, 65 hours, with about 13 hours to charge fully. Charge it between 10 and 40°C. The pack is interchangeable with alkalines, so a flat pack is not a lost day.
How tough is it?
Rated IP66 for dust and water. It operates from -20 to +50°C (-4 to 122°F) and is stored from -30 to 60°C. Weight is about 2.6 kg (5.7 lb) with alkaline batteries, 2.8 kg with the BT-79Q. The tripod thread is the standard 5/8 x 11 used on surveying instruments.
What laser class is it?
Class 1, 635 nm, to IEC 60825-1 Ed. 3.0, as stated in Topcon's specification. It is still a laser: do not stare into the aperture and do not point it at anyone.
Where can I get the manual?
Right on this page. We host Topcon's RL-HV instruction manual (with our contact sheet added on the front and back), the check-and-adjustment guide and the Laser Manager quick guide as free PDF downloads. Topcon's own pages are untouched.
