Product overview:

Spectra LL100N Premium Laser Level Kit:

The Spectra Precision LL100N is a new standard in affordable professional laser tools. A durable & accurate laser level to withstand the toughest of job sites.

The fully automatic, self-leveling Spectra Precision® Laser LL100N sets a new standard in rugged reliability, handling a wide variety of general construction applications. Even in the toughest job site conditions, the LL100N consistently delivers reliable, accurate performance to increase your overall productivity and cost-savings.

The laser can be mounted on a tripod to send a 360° plane of laser light over the entire work area, allowing one person to take accurate, self-leveled elevation measurements up to 175 metres away with the supplied HR320 laser detector. One button operation makes this a simple task.

The LL100N is designed to be durable and reliable, day in and day out, and features superior drop and weather protection. It can withstand drops of up to 3 feet (1 m) onto concrete and tripod tip-overs up to 5 feet (1.5 m).
This ruggedness results in reduced downtime and lower repair costs.

This instrument is capable of handling a wide variety of elevation control applications.
Versatility is added with DUAL-axis manual slope capability, for setting out driveways, ramps, and drainage lines etc with control via an optional RC601 remote control.

If you need?:

Looking for the LL100N 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 Precision LL100N Kit also includes the following:


Telescopic Levelling Staff (Model: TLS4S)

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.

Product Comparison:

Please note: Some features listed are only available using optional accessories.

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.

Kit comprises of:

LL100N Rotary Laser Level (checked and pre-calibrated)
HR320 Laser Detector, Staff mounting bracket & Batteries (Option to upgrade to HL450 Laser Detector)
2 type 'D' Duracell alkaline batteries

Hi I live in New Zealand do I still pay VAT as I might have to pay GST on arrival .cheers Ed


  • Posted by Laser Levels Online - Support on Wednesday 20th of January 2016

    Hi Ed,

    When you add the products to the basket and go through to the checkout, you will need to enter you billing and delivery address as "New Zealand". This will then automatically remove the UK VAT.

    Please note, you will still be charged GST and Duty for importing a product into New Zealand, but this is done on a local level and not charged at time of ordering.

    All international order can be paid for via Paypal or Bank Transfer. We are sadly unable to accept credit card payments where the billing address is outside of the UK.

    If you have any further questions or require any additional assistance please do not hesitate to contact us.
    Best regards
