The BY.TECH LG20 is Bytech's second-generation multi-purpose laser mapping system, a gimbal-mounted version of its high-power laser equipment. It comes with multiple hot-swappable modules and red-blue flashing lights, and installs without tools.
Key Features
- Compact design, quick installation — Small, lightweight and easy to install; it can be mounted by hand without any tools.
- Versatile, combinable functions — Quick-release, interchangeable modules come in several types, such as guidance, mapping, fill light and lighting. The dual-module design meets a wide variety of needs.
- Hot plugging and fast module swaps — Laser modules support hot replacement, with a simple, fast clip-on design that helps get the job done sooner.
- Smart light concentration and lens follow-up — A 2-axis stabilized gimbal with an AI algorithm concentrates the light automatically and moves in sync with the lens.
- High heat dissipation, continuous illumination — The all-aluminum-alloy body dissipates heat well and slows light degradation, protecting long-term illumination.
- Altitude mapping and rapid deployment — A fast, accurate overhead perspective solves the lack of temporary warning tools at the scene.
