DeWalt 20V MAX Green Cross Line Laser vs DEWALT Green Cross Line Laser

Both are DEWALT green cross-line lasers with the same ±1/8" at 30 ft accuracy, 180 ft visible range, 330 ft detector range and IP54 rating, so the lines you see are effectively identical. The DCLE34021B runs on the DEWALT 20V MAX battery platform and gives 16 hours on a 2.0 Ah pack; the USB Rechargeable kit has a built-in battery with about 11 hours per charge and adds a remote-control option. Owners of other 20V MAX tools should take the DCLE34021B; anyone who wants one self-contained kit with no battery platform should take the USB kit.

• Choose the DCLE34021B if you already own DEWALT 20V MAX batteries and want unlimited runtime by swapping packs plus mode memory that keeps your last beam setup.
• Choose the USB Rechargeable kit if you want a compact all-in-one laser you charge by USB and can control remotely, without buying into a battery platform.
