The Spectra Precision® LL300N Laser Level features a very robust design with a metal sunshade that provides superior drop and weather protection. Built to withstand severe drops of up to 1 metre directly onto concrete, or up to 1.5 metre when pushed over on a tripod, means less downtime and cost due to damage caused by accidental an drop or tipover...... and lower repair costs over the life of the product.

In addition, a high level of dust/water protection to IP66 (Dust tight & Protected against powerful jets of water) makes the LL300N suitable for the most demanding of worksites.

The LL300N's fully automatic self-levelling capability provides fast, accurate setup; with just one button press.

The included Rechargeable NiMH battery pack or optional alkaline batteries keeps the unit working with no downtime due to power loss. 

The optional RC601 remote control gives you the option of controlling the unit from the measuring staff position, when doing slope matching. It also offers single-axis slope mode with self-levelling in the cross axis, providing more accurate grade measurements.

Laser detector upgrades are available. Opt for the Spectra HL450 if you require a digital offset detector which can show up to 40mm either side of true level.

Spectra LL300N’s purchased from Laser Levels Online now get a bonus year added to the 5 Year manufacturer’s warranty making 6 years in total. Why buy the Spectra LL300N anywhere else?

Want to set slopes or gradients?

If you want to be able to set slopes or gradients with the LL300N you will need to add the Spectra RC601 remote control to the kit.

The optional RC601 remote control gives you the option of controlling the unit from the measuring staff position, when doing slope matching. It also offers single-axis slope mode with self-levelling in the cross axis, providing more accurate grade measurements. Without the remote, you will not have the ability whatsoever to set slopes or gradients as it cannot be controlled from the laser keypad.


Operating diameter of 500m with supplied Detector
Single & Dual grade option gives increased flexibility (Requires optional RC601 remote control).
Increases productivity with fast set-ups, fewer mechanical parts, and automatic self-levelling 
Maintains performance even in rainy, dusty and other harsh job site and weather conditions 
Durable design reduces downtime due to drops and tripod tip-overs 
Minimizes power costs, increases reliability with choice of rechargeable or alkaline batteries 
Customizable to your needs with a choice of three optional detectors, the HL450, the CR600 or the CR700 for machine control.

An accuracy of +/- 2.2mm @ 30 metres is equivalent to 0.073 mm/m and to put that into perspective, the best premium German spirit level has an accuracy of +/- 0.5 mm/m or +/- 15mm @ 30 metres.

Dual Grade facility:

Dual axis X and Y axis up to +/-10% (1 in 10)

Both X & Y axis can be set to give a maximum fall of up to 1m at 10m distance away. (ie. 1 in 10 & +/-10% grade)

Note: You will require the optional RC601 remote control to set grades/slopes.

This is a superb bit of kit. Im on a fairly large site and this laser level works perfectly for setting out and finding levels. its really easy to use. It arrived really fast once ordered and i went for the up grade on the detector as it was a good price. Great bit of kit!

Spectra Precision Laser products with this warranty that have failed will be repaired FREE OF CHARGE for five years from the date of purchase. From 01/11/21 all Spectra LL300N's purchased through Laser Levels Online will also have an additional 1 Year Bonus Warranty added to the standard 5 Year warranty provided by Spectra - making 6 years in total.

If you need?

Looking for the LL300N with the full length System Case otherwise known as the "gun / guitar" case?

The case that is included in our kits is the smaller "briefcase" style. Not the larger "gun / guitar" / system case style.
We did used to sell the larger system case as an option but what we were finding is that if the kit has got wet on site then it's easy to dry off the laser and store dry.
If you have the larger case which also stores the tripod and staff it's very hard to dry a wet and dirty tripod and staff and so we now only sell the smaller case which doesn’t store the tripod and staff.

Also included in the kit

The Spectra LL300N Premium Kit also includes the following accessories:

4m Telescopic Levelling Staff (Model: TLS4S)

4m, 5-section, Telescopic Levelling Staff. 
Five robust aluminium sections with abrasion proof scale.
Closed length height 970mm, extending to maximum height of 4m.
Automatic locking buttons when extended.
Millimetre scale on back and E-graduations (1cm) markings on front
Rear mm scale (for use with laser levels) has ZERO mm marking at ground level.
Red / Black coded front sections.
Accepts all Laser detector mounting brackets.
Removable, rear-mounted circular Bubble Level.
Carry sleeve.
Height: 0.97m closed length to extended max 4m. 
Weight 1.15kg.

Surveying Tripod (Model: S-LAT)

Maximum 1.5m height. 
Robust aluminium tripod. 
Extending legs with quick-release, toggle clamp adjustment. 
Flat top, mounting head. 
Head size 130mm
5/8 inch x 11 thread. 
Closed length 0.925m
Max. Opened height 1.5m approx.
Weight: 3.4kg

Upgrade the kit to include the Spectra HL450 Detector

The Spectra Precision HL450 Detector is an easy-to-use tool that accurately measures elevations across the site, and is ideal for use with any rotating laser level.

The HL450 features a digital readout of elevation that provides a numeric display of ±40 mm to 1mm resolution. The readout is displayed on the large front and rear LCD's and shows exactly how far the elevation is from on-grade.

Accurate measurements can be made without moving the rod clamp, saving time and increasing productivity.

The HL450 has a 102 mm (4 inch) reception height, double the typical industry standard, which allows quick acquisition of the laser beam. Also included is a patented anti-strobe sensor that prevents construction lights from setting off the Detector and makes it easier to identify the laser beam signals.

The Detector is designed to survive the tough construction site conditions. It is totally waterproof (IP67) and can withstand a drop up to 1.5 meters (5 feet) onto concrete.



Digital Readout of Elevation allows faster readings by displaying the exact numerical distance from grade, eliminating the need to move the detector to get to "on-grade".
Anti-Strobe Sensor stops construction strobe lights from setting off the detector and eliminates phantom strikes for easier identification of true laser beam signals.
Large reception height allows faster readings by acquiring the beam quickly, and makes it easier to stay in the beam.
Durable in tough environments provides less downtime due to damage or service requirements after accidental drops.


HL450 Detector upgrade includes:

HL450 instrument
Alkaline batteries x 2
Mounting bracket
Instruction & safety manual
24 Months Warranty

Please Note: If you upgrade to the HL450 Detector, the default HR320 Detector will be removed from the kit.


Do you need ShockWatch® adding to your Laser?

The optional ShockWatch impact indicator clip is a tamperproof, mechanically activated device that turns bright red to indicate mishandling or after the Laser has received an excessive impact. Designed to mount directly onto the Laser Level, the clip is compact and economical and provides 360° impact detection alerting the user to check the Lasers Calibration before use. If this option is selected, our Technicians will fit your Laser with a Shockwatch prior to dispatch, giving you and your users extra piece of mind on the job site.
For further details of ShockWatch®, please Click Here.

Need to mount a Detector on Plant equipment?

The LL300N can be used for machine control by using a magnetic CR700 Detector, which can be purchased as an "upgrade" or as an optional extra.

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.
