the Receiver Finds It.

A line laser is easy to see in a dim room and hard to see in daylight or across a big space. The Leica RGR 300-D picks the line up for you, then does what the beeper-only receivers cannot: it shows how far you are from the line as a number, in millimetres or inches.
It detects both red and green lines, reaches 80 m (262 ft), and has lit displays on the front and the back. Built-in magnets hold it on metal, the staff clamp holds it on a rod, and it is sealed to IP65. Leica designed it to pair with the Lino L2, L2P5 and L6, and it works with any red or green line laser that pulses at 10 kHz.

Key Features
What the RGR 300-D
Does for You.
Does for You.
A Number, Not a Guess
The display shows how far the beam is from the centre in millimetres or inches, across a 60 mm window. You do not interpret a row of arrows — you read the offset and move the mark by that much.
DIGITAL READ-OUT
Reads From Both Sides
A lit LCD on the front and one on the back means you pick the side that keeps the laser line unobstructed. Whoever is holding the receiver is never in their own way.
FRONT AND BACK
Built-In Magnets
Magnets in the body hold the receiver on any metallic surface — a stud track, a steel beam, a ceiling channel — and free your hands.
HANDS FREE
Red or Green
Detects both 635 nm red and 525 nm green lines, so one receiver covers every red or green line laser that pulses at 10 kHz. Change lasers later and this still works.
RED + GREEN
Up to 80 m
Reach 2 m to 80 m (262 ft) from the laser so you set up less often in large rooms. Range depends on the lighting in the space.
LONG RANGE
Made for the Jobsite
IP65 dust and jet-water protection, a 1.2 m (3.9 ft) drop rating, and 24 hours on two AA batteries.

How It Works
Three Steps
to the Mark.
to the Mark.
1
Set the accuracy
Press the accuracy key to choose ±0.5 mm, ±2 mm or ±5 mm. Fine for precision layout, coarse for quick rough-in.
2
Catch the line
Hold the receiver across the laser line. The display arrows tell you to move the receiver up or down, and the beeper sounds at 90 dB, 70 dB or off.
3
Read the offset
The number on the screen is your distance from the line. When it reads zero, the reference notch on the side of the receiver is on the line — mark it.
Press ON/OFF once to switch on; press again for the backlight; hold for 2 seconds to switch off. Press the beeper key to step through high, medium and off, and press both keys together to change between mm and inches.
Applications
What It Is For
Ceiling and Soffit Layout
Pick up a ceiling line from a distance and mark it from the ladder, reading the display from the side that faces you.
Partition and Drywall Layout
Carry a laser line across a large room and find it again when the room is bright and the line is faint.
Tile, Flooring and Cabinets
Mark a level or plumb line across a wall to a stated tolerance instead of eyeballing a faint stripe.
Electrical and Plumbing
Hold the receiver on a stud track or pipe with the built-in magnets and mark the offset while both hands stay free.
Large Rooms and Warehouses
Where the line fades before it reaches the far wall, the receiver extends your usable working range to 80 m.

Line Laser.
The RGR 300-D detects red (635 nm) and green (525 nm) lines from any line laser that pulses at 10 kHz. Leica designed it to go with the Lino L2, L2P5 and L6, and it works with the lasers across that range, so if you change from a red laser to a green one you keep the receiver.
Leica also make the RGR 200, which gives acoustic guidance only. The RGR 300-D adds the digital read-out and the lit front and back displays.

Questions & Answers
RGR 300-D
Questions We Get.
Questions We Get.
What is the Leica RGR 300-D?
It is a digital line laser receiver, Leica article 1017990. It finds the laser line for you when the line is too faint to see — in bright light, at long distance — and shows the offset from the line as a number in millimetres or inches.
Which laser lines does the RGR 300-D detect?
Both red (635 ± 5 nm) and green (525 ± 5 nm). Leica state it is compatible with all red and green line lasers operating at a 10 kHz frequency, and ideally designed for use with the Leica Lino L2, L2P5 and L6.
Does it work with a rotating laser?
Leica specify the RGR 300-D for line lasers, and that is what we sell it for. For a rotating laser, use a Rod Eye receiver, which is built for that beam — the Rod Eye models are linked lower on this page. If you are not sure what your laser is, call us on 1-877-866-5721 before you order.
How far can it detect a line?
From 2 m to 80 m (6.6 ft to 262 ft). Leica note that the working range depends on the lighting conditions, so expect less in bright sun and more in a dim room.
How accurate is it?
You choose the accuracy: ±0.5 mm (±0.02 inch), ±2.0 mm (±0.08 inch) or ±5.0 mm (±0.19 inch). The accuracy key cycles through them.
How do I switch between millimetres and inches?
Press the beeper key and the accuracy key together. The display changes between mm and inches.
Can I use it vertically and horizontally?
Yes. The quick guide shows both: hold it level to find a vertical line, or upright to find a horizontal line. The display arrows tell you to move the receiver up, down, left or right.
What does the digital read-out show?
The distance from the centre of the line, within a 60 mm (2.4 inch) window and up to ±25 mm (±1 inch) either side. Outside that, the arrows point you toward the line.
How long do the batteries last?
About 24 hours on two AA 1.5 V batteries, which are supplied. A low-power alert shows on the display, and the receiver switches itself off after 30 minutes without detecting a line.
How tough is it?
It is rated IP65 against dust and jet water, survives a 1.2 m (3.9 ft) drop, and works from −10 °C to +50 °C (+14 °F to +122 °F).
How do I mount it?
Three ways: the supplied staff clamp onto a grade rod or pole, the built-in magnets onto any metallic surface, or the bracket thread on the back. A spirit level on top helps you hold it plumb.
Is it safe around a pacemaker?
Keep it away. Leica warn that the integrated magnets may affect a pacemaker, so do not use it near one. The signal sound is also louder than 80 dB(A), so do not hold the receiver to your ear.
What is the difference between the RGR 300-D and the RGR 200?
Leica make both. The RGR 300-D has the digital read-out and lit displays; the RGR 200 gives acoustic guidance only. Choose the 300-D when you want to read the offset as a number.
What does the warranty cover?
Leica give a 3-year warranty when you register the receiver within 8 weeks of purchase at www.disto.com/warranty.
