Spectra Signal Transporter ST805

Spectra Precision announce a brand new product bundle that is going to make your work life much easier!
The Spectra Precision® ST805 Signal Transporter extends the radio range of compatible lasers by up to 2x the normal range.
The ST805 is a small, compact device that attaches easily to a pole or stake with the included mounting strap. On the jobsite, it is placed between the laser and the remote control, the Laser Remote App or an HL760 detector. Once paired with the laser, the ST805 will then re-broadcast the radio signal, doubling the range of the current RC402N, RC602N, RC603N and RC803 remote controls.

Contractors can now carry out the full range of operations from the radio remote control or App including Grade Matching, PlaneLok and Axis Alignment. This reduces the need for multiple set-ups when working over longer distances and provides the contractor with more control, especially when carrying out alignments. In addition, the ST805 extends the range of the Fingerprinting function when used with an HL760 detector, reducing errors from other lasers operating on the same jobsite.

The ST805, now with Bluetooth, can be paired with the new Spectra Laser Remote App. Combined with the ST805, you can control your Spectra laser right from your own smartphone or device via the App on Android (IOS coming soon). This gives a large, graphical interface to change settings, rotational speed or grade value of your laser. It is easy & intuitive to use.

When used with Spectra DG pipe lasers in manholes, the ST805 mounts on top of the manhole to assist the RC803 remote to maintain radio communication between the laser and the remote control.
This bundle is a unique blend of hardware and software that improves productivity and convenience.


Doubles the range of communication between the remote control and compatible laser levels up to 100m – reducing the need for multiple set-ups over long distances.
Increases the operating range between the laser and HL760 for automatic functions such as Axis Alignment, Grade Match and PlaneLok on longer-range applications or when the products are close to the ground.
Aids in communicating with a Spectra pipe laser in the manhole.
Increases the detector working range for Fingerprinting – reduces errors from receiving laser strikes from other lasers on the same jobsite.
Single-button operation for simple, no-fuss operation.
Easy to use and set up – no learning curve.
New Spectra Laser Remote App connects your smart device with your laser via Bluetooth connectivity.

Product App

FREE Spectra Precision Laser Remote App for Android (IOS coming soon)

The Laser Remote App controls your Spectra Precision Laser. It is easy and intuitive to use.
When used with the ST805 signal transporter, the Laser Remote App connects to the following Spectra lasers: LL300S, HV302(G), GL412N, GL422N, GL612N, GL622N, GL622IR, UL633N, DG613(G) and DG813.
Use your smart device to have a large graphical interface on hand to change your laser settings. Specific functions are laser dependent and may include changing manual or single axis slope mode, changing grade, changing rotation speed, set laser to standby mode, changing sensitivity settings, user name, HI alarm and password.

Please Note: The Laser Remote App is free but it must be paired with the Bluetooth® enabled ST805 Signal Transporter, in order to control your laser.

I have worked in the construction industry for over 25 years dealing with hundreds of suppliers, the quality of their products is fantastic, the delivery is next day so you can't complain about that and the customer service is second to none, if you need a leveling tool don't bother going anywhere else.
