In order to make the IR101SP water resistant, it is necessary to cover the laser with a protective lens during the manufacturing process. This causes the pointer to be somewhat lighter than other laser pointer devices. You can test the pointer be holding the IR101SP 4 to 6 inches for a solid surface and depressing the "Measure On" button while in the "Laser On" mode. NEVER aim the IR101SP towards your face or eyes.
