BullseyeBore Core utilizes low power lasers in the range of 1mW that are certified as Class 1 lasers. Class 1 lasers are eye safe as defined under the US FDA regulations and are thus very low in output power. As a result, none of the current BullseyeBore Core versions will be operationally visible in DIRECT sunlight. However, the Core Green versions are designed to be operationally visible in INDIRECT sunlight or in bright indoor conditions. If you intend to use BullseyeBore Core in bright indoor conditions or indirect sunlight, choose the Core Green versions CG1-100 and CG1-101.
As with all drilling applications, some testing should be done first in the expected environmental and visibility conditions to assess both worksurface pattern visibility and overall safety.
