Product overview:

Spectra LL300S Premium Laser Level Kit:

The Spectra Precision Laser LL300S features a rugged design with a metal sunshade that provides superior drop and weather protection (IP66).

The rugged LL300S laser can withstand drops of up to 1 metre (three feet) onto concrete and tripod tipovers up to 1.5 metres (five feet). This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.


The LL300S laser's self-leveling capability and optional RC402N radio remote control result in outstanding accuracy and ease of use. Since the LL300S automatically levels itself when turned on, setup is easy with fewer controls to deal with. The arrow buttons on the keypad offer easy slope matching, with a controlled setup using the HI-alert function.

The optional RC402N radio remote control with a 100m range makes slope matching, a single person operation.


Laser detector upgrades are available: Select the standard HL450 or upgrade to the Spectra HL760U.

Select the CR600 detector for occassional machine control work or either of the LR30, LR50 or LR60 packages - for the regular user.


Included in the LL300S purchase price is a 5-Year "No Cost - Warranty".  (for full details, please see below)


Operating diameter of 800m with supplied HL450 Detector. 

Increases productivity with fast setups, fewer mechanical parts, and automatic self-leveling

Maintains performance even in rainy, dusty and other harsh job site and weather conditions

Durable design reduces downtime due to drops and tripod tipovers

Minimizes power costs, increases reliability with choice of rechargeable or alkaline batteries

Increased flexibility with an optional long range Radio remote control

Comes with choice of the standard HL450 detector or upgrade to an HL760U, so you can choose the best option to suit your application.

Calibration and servicing:

We check and calibrate all Lasers prior to dispatch, to ensure they meet or exceed the manufacturers published specifications at the time of shipment from the factory.
If you routinely work on large job sites, which require you to have a physical Calibration certificate, issued in your name and matched to the Laser via its serial number, you must ensure you tick the above box marked "Paper Certificate" (where applicable) to add a Calibration certificate to your order. The Certificate will then be generated and included with your Laser. Please note the issuing of a Calibration certificate DOES NOT delay or hold up the despatch of your Laser in any way.
