The McGARF Wall/Back-Mounting Alignment Laser MK4 has been designed for use in drives/drifts that extend beyond the scope of the McGARF Alignment Laser.

The instrument can be fixed either on the back, on a curve or on the side wall, preferably at least 3 metres off the ground to protect it from being damaged.

The instrument has a coarse adjustment and a fine adjustment facility which makes it very easy to set up the line and grade.

It also has two lasers which are used for auditing purposes. One laser points to the back and the other to the opposite wall. Where they strike, the surfaces are marked by the surveyor and can then be used as a check to make sure that the instrument has not been knocked off line.

The main beam is set to come on for approximately 6 minutes and it will automatically turn off, the other two beams come on for 60 seconds, thus saving battery life. It can be easily reactivated if still needed.

The battery can be replaced when flat without removing the instrument from the wall.

The McGarf Wall/Back-Mounting Alignment Laser is remotely controlled by a hand-held transmitter with a range of up to 60 metres.

The advantage of this instrument is that it can be relocated easily and does not require the use of a cumbersome 12V car battery.

Carry case included.

Available for use in Australia.

McGARF Grade Line Laser
Grade line laser With the McGARF Grade Line Laser, a miner or a supervisor can mark the grade lines on the side walls.

The McGARF Grade Line Laser will also give you a levelled horizontal line at the same height as the laser dot on the front wall.

How it is used:

Install the the McGARF Alignment Laser into the sleeve and this will send a laser dot, on line and grade, to the front face.

Place the McGARF Grade Line Laser on to the McGARF Alignment Laser, level it using the spirit bubble and lock it in place.

Turn on the grade line laser.

The laser line will either be above or below the dot on the front wall.

Using the adjustment screw, line up the laser line with the dot.

Once this has been done, you now have a level line across the front face and a grade line down both side walls.

Using this equipment, marking the grade lines can now be done by anyone.
