The LL300S Laser Level from Spectra Precision is a fully automatic self-leveling unit for all general concrete and site preparation applications. It is easy to use – turn it on, it levels, then spins. With the addition of the arrow buttons on the laser keypad, grade matching can be performed while the other axis remains self-leveled. The optional RC402N radio remote control makes slope matching a single-person operation. This slope is useful for driveways, ramps, drainfields or water runoffs. The operating diameter is 2,600 feet and accuracy is plus-or-minus 1/16 inch per 100 feet. 888/272-2433; www.spectralasers.com.
