Discreet and child resistant, the Patent Pending Artemis 2 Gun safe was designed to reduce accidental firearm handling and accidents. However, it also works perfectly for those looking for a secure place for their firearm. Artemis 2 features a one-touch biometric fingerprint scanner, called "Second Touch". The high quality scanner is similar to fingerprint scanners on smartphones; easy to program, use, and can accept up to 200 unique fingerprints. It's small and discreet enough to fit under a bed yet large enough to easily accept 1911 model handguns and ammo. Artemis 2 is constructed from a weapons-grade plastic Polycarbonate polymer, the same polymer used in bulletproof glass and body armor! A loud tamper alarm will sound after 5 unauthorized attempts, and will cease with an authorized fingerprint scan. Additionally, the case has four mounting holes an anchoring cable, and a high security 2 latch system. The included 4 AA batteries provide up to 4,000 scanner operations, or ~ 1 year of use, at the end of which a low battery alarm will sound. A high security tubular-style key is also included. Interior Measures : 10 5/16" x 6 7/8'' x 2 3/4" Exterior Measures 11 1/2'' x 11 1/2'' x 3 3/16,'' "Artemis" is a Registered Trademark.
