AdirPro Rotary laser detector, red only, 2000 ft
The only receiver here that publishes how fine it can split the beam — and the only one that admits its range belongs to the laser.
- Stated accuracy
- TWO accuracy bands: ±1/16 inch (1 mm) and ±1/8 inch (2.5 mm), stated, with the detector directing the user to position the laser higher or lower on the rod. It is the ONLY receiver on this shelf to publish bands at all, and this shelf's introduction lists them as one of five comparisons — a fine band finds grade slowly and precisely, a coarse one finds it fast
- Stated dimension or range
- A working range of 2000 feet — "depending on laser", stated. That qualification is the only honest one on this shelf: a receiver reveals the laser's range rather than creating it, and two thousand feet describes what a rotary laser can throw, not what this box can do alone
- Functions
- ROTARY lasers only, and RED only: compatible with most standard red rotary lasers, stated, working in all lighting conditions. It is the only receiver on this shelf that will not serve a line laser, and the only one that will not see a green beam — which rules out most of the cross-line lasers on this site
- Display
- A dual-sided crisp LCD showing elevation, grade sensitivity, and audio and battery status. Showing the SENSITIVITY on the screen is the detail that makes two accuracy bands usable: you can see which band you are in rather than remembering
- Measuring mode
- A built-in bubble level, stated. On a detector clamped to a rod that is the check that the receiver itself is not tilted, which would offset every reading by the same amount
- Power
- A 9 V battery giving approximately 40 working hours, with auto shut-off after 10 minutes of inactivity. Forty hours against about seventy on another receiver here
- Ingress protection
- IP55, dustproof and water-jet resistant, in a hard plastic housing with a rubber casing. IP55 is the highest rating on this shelf, where the other two are IP54 — jets rather than spray, which on a grading job in the rain is the relevant one
- Supplied
- A rod mounting bracket with 1/4 inch threading on the nut and screw, stated included. This shelf's introduction asks about clamp fit; 1/4 inch rather than 5/8 means it suits a compact rod rather than a survey tripod

Best for: A red rotary laser on a grading job, where the difference between 1 mm (0.04 in) and 2.5 mm (0.10 in) decides the fall
