PROWLER Weapons Sight Filters are designed to improve vision under extreme lighting situations -- day and night -- and during all weather conditions. This filter technology, available from Spectrum Technologies, is compatible with high/low-powered optical sights, holographic weapon sights and traditional open sights. PROWLER Weapons Sight Filters enhance standard red-green laser target dots while providing improved overall vision. Custom-sized/shaped PROWLER Weapon Sight Filters can be mounted in/on the objective or ocular eyepiece of nearly all optical sights, or by placing them in readily available flip-open scope covers.
