For the release of Rock Mapper version 2.0 (which comes with a new LiDAR Scanning tool) we have developed a new Dual LED Light Array which is directly attached to the iPad Pro. It's compact, waterproof, powerful (3,000 Lumen), light-weight and has been designed for Underground Face Photography & Underground Face Scanning.
The Dual LED Light Array comes as part of the Rock Mapper Hardware Kit and also includes a Wireless Charging Dock.
