Spectra Precision LL300N and LL300S

The Spectra Precision® LL300S is a ruggedized, fully automatic self-leveling Laser Level for all general concrete and site preparation applications. With the addition of the arrow buttons on the transmitter, grade matching can be performed whilst the other axis remains self levelled.
The Spectra Precision® LL300N Laser Level features a rugged design with "hard hat" rotor protection that provides superior drop and weather protection. Built to withstand severe drops of up to 3 ft (1 m) directly onto concrete, or up to 5 ft (1.5 m) when pushed over on a tripod means less downtime and cost due to damage caused by accidental drop.

What is the main difference between the LL300N and LL300S?

[@SpectraPrecisionDivision]

The are the main differences between LL300N and LL300S:
Accuracy LL300N +/- 3/32 inch at 100 feet (+/- 2.2mm at 30m)
Accuracy LL300S +/- 1/16 inch at 100 feet (+/- 1.5mm at 30m)
LL300N can be used with an infrared remote control (RC601); remote range typ. 165 ft (50m)
LL300S can be used with an radio remote control (RC402N); remote range typ. 330 ft (100m)
Usually radio is more stable and reliable to communicate between the products; even more under strong sunlight conditions
In both cases the remote control provides more features and functions to the product.
receiver range LL300N is 1600 ft (500m)
receiver range LL300S is 2600 ft (800m)
LL300S has the function mask mode; up to three windows the laser beam can be switched off; this is not possible with LL300N
LL300S can be paired with receiver HL760 so the function 'fingerprint' is available; this means the HL760 detects the laser beam of the paired transmitter only; this function is not available with LL300N
