Product overview:

The automatic, self-levelling Spectra Precision Laser LL300 is our most rugged laser level.

The Spectra Precision® Laser LL300 is rugged enough to survive drops of up to 1 metre (3 feet) onto concrete and can be tipped on a tripod up to 1.5 metres (5 feet) and keep working. This strength, combined with full weather and dust proofing (IP54), results in reduced downtime and lower repair costs over the life of the product.

The LL300's self-levelling capability results in outstanding accuracy and ease of use. Since the LL300 levels itself when turned on, setting up is easy with just one button press. 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.


Included in the LL300 purchase price is a newly introduced: 5-Year "No Cost - Warranty". (see below)


Operating diameter of 400m with supplied Detector

Dual grade option included in the Premium Exterior kit. (Increased flexibility with remote control slope option.)

Hello! I have acouple of questions regarding the Spectra LL300. I live in sweden, and here we have 240 volts AC Outlets. Do you have the same current in the UK? What are the specs of the mains charger that is supplied with the spectra ll300, will the plug fit in my swedish outlet, and will the unit blow up if i connect it to 240Volts. If the plug doesnt fit here in Sweden, I can simply replace the plug.

    Hi Staffan,

    Thank you for your message.

    The charger that is supplied with the LL300 is:

    In the UK we have 3 Pin plugs.

    Please see this guide to International plugs:

    You will therefore require a plug adapter.

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