Frequently Asked Questions — Spectra Precision HL760
How far can the HL760 detect a rotating laser?
The HL760 detects rotating laser planes up to 600m from the laser instrument under good conditions. In bright sunlight, effective range is typically 300–400m. Using a laser with higher RPM rotation improves detection at long range.
Is the HL760 compatible with Topcon and Leica lasers?
Yes. The HL760 includes a universal detection mode that works with most 635nm red-beam rotating lasers regardless of brand. For automatic blade control, digital output compatibility depends on the blade control system manufacturer.
What does the numeric display on the HL760 show?
The HL760 displays the distance from the detected laser plane in millimeters, positive above grade and negative below grade. This lets operators set a specific height offset from the laser reference without repositioning the mast.
How is the HL760 powered in a machine-mount configuration?
When mounted on a machine for automatic blade control, the HL760 is typically powered from the machine's 12VDC electrical system via the supplied power cable, eliminating the need for AA batteries during continuous machine operation.
