Spectra LL300N Deluxe Laser Level Kit:

The NEW Spectra Precision® LL300N Deluxe Kit now allows you to get the best of both worlds. A Tough LL300N Groundworks rotary laser for your outdoor work and a rugged & bright LT20 Indoor Cross Line Laser for all your indoor jobs! Get more done with this fantastic deluxe laser kit.


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-leveling capability provides fast, accurate setup; with just one button press.


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.


Included in the LL300N purchase price is a 5-Year "No Cost - Warranty".
