Spectra Precision ST805 Transporter - Remote Amplifier

Extend Your Wireless Reach on the Jobsite

The Spectra Precision ST805 Transporter is a professional-grade wireless communications amplifier designed to dramatically extend the operating range between Spectra Precision rotary laser systems and their compatible remote control devices. Whether you're grading a large commercial site, paving a wide parking lot, or managing deep utility trenches, the ST805 keeps your crew in communication and your laser under control from distances that would otherwise break wireless connectivity. Built for the demands of real contractor work, the ST805 reduces unnecessary walking, improves site safety, and keeps your laser positioning workflow moving efficiently.

Product Overview & Jobsite Applications

Large-scale construction projects often require operators to position themselves far from the laser instrument — sometimes across hundreds of feet of open terrain, through job trailers, or around heavy equipment. The ST805 Transporter acts as a signal relay between your Spectra laser transmitter and the handheld remote, amplifying and re-broadcasting the wireless signal to maintain reliable, responsive control at extended distances. The result is fewer interruptions, less foot traffic across active work zones, and more precise grade control when it matters most.

Job Applications

Large-Scale Grading & Earthwork: Control your Spectra rotary laser from the cab of a motor grader or scraper at distances that standard wireless simply can't reach. The ST805 keeps grade adjustments instant and accurate without stopping the machine.

Paving & Flatwork: On wide commercial paving jobs or large slab pours, position the ST805 mid-site to maintain remote control of your laser across the full work area without signal dropouts.

Utility & Pipeline Trenching: Deep trenches and elevated spoil piles can block wireless signals. The ST805 Transporter overcomes line-of-sight obstructions to keep your laser and remote in reliable communication.

Site Prep & Subdivision Development: When clearing and grading large residential or commercial subdivisions, the ST805 lets a single operator manage laser positioning across multiple work fronts without returning to the instrument.
