Spectra LR30W-MM Wireless Magnetic Machine Detector with Wireless Cab Display & Magnetic Mount

Rugged 360-degree laser detector with wireless connectivity to RD20 Wireless Cab Display

The Spectra Precision® LR30W Wireless Laser Detector is designed to be used as a stand-alone display detector for skid-steer loaders, backhoes, excavators, dozers, scrapers, levellers and trenchers. Designed for use in harsh environments, the LR30W is 100% weatherproof and features 360-degree laser detection. 


The Spectra LR30W Machine Control Detector is designed for outdoor machine grading and links wirelessly to the Spectra RD20 remote display to provide an in-cab display of elevation and audible signals. This standalone laser detector can be used on a wide range of machines, such as dozers, backhoes, excavators, scrapers, skid steers and levelers. The LR30W also features a 360-degree reception and works with any red beam, rotating lasers.

LED and Display Channels:

With adjustable, ultra-bright LED with green on-grade display, this Spectra machine control receiver offers clear viewing to match ambient lighting conditions. In addition, moving and getting back in the beam is easy with five channels of grade information and a directional out-of-laser beam indicator.


For easy access to the most common functions, the LR30W features a touch panel that provides low-battery warning, dead band selection and display-brightness buttons.

Multiple Accuracies:

The LR30W offers three accuracy settings: fine, medium and coarse. This allows construction professionals to work with maximum flexibility to meet jobsite requirements, from rough grading to final finishing.

Precise Laser Strike Positions:

For the highest accuracy and grade performance, this wireless machine control laser detector provides a continuous, absolute laser strike position to precisely measure the actual height deviation from on-grade.

Mounting Knobs:

The LR30W’s large front-facing knobs allow for quick and hassle-free installation to a round pipe or square tubing. (An MM-1* magnetic mount is also included.)

Rugged and Water Resistant:

Constructed of durable polycarbonate and aluminum die cast housings, this machine control receiver can withstand harsh weather and construction site conditions. It also has an internal isolating shock mount that protects the unit against drops. Using the included rechargeable NiMH batteries, it works up to 50 hours or approximately 75 hours with 4 x type C alkaline batteries.

Magnetic Mount (MM-1*)

A very powerful magnetic mount is included in the kit, having a 750mm support post giving unparallelled fixing support for the LR30W detector.

This Spectra Precision wireless machine control receiver comes with a hard carry case, rechargeable batteries, charger and 2-year manufacturer's warranty.

Technical specification

The Spectra LR30W-MM will operate with any RED beam rotary lasers levels. It will not work with GREEN beam lasers. There are currently no magnetic machine detectors for green beam lasers.

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.
