Handheld Metal DetectorUltraScan's high sensitivity is invaluable in anti theft applications where small metal objects must be protected. Jewelry, electronic products, computer processors, tools etc. can be detected.Optimum efficiency on a range of applications is achieved through user adjustable sensitivity.Ultra-Scan's high sensitivity allows a search to be non-intrusive and hands-off by minimizing physical contact with the subject.The lightweight construction, comfortable grip, large screening area, fast detection circuitry all contribute to higher efficiency screening and reduce operator fatigue.Features: For fast weapon screening and theft prevention Highly sensitive scanning circuit - fast scan rate Instant response - clear visual and audio alarms No false alarms - digital go-no go threshold circuit High sensitivity for non-intrusive body searching Elegantly styled molded ABS housing Electronic switching with tactile feedback Three state Blue LED alarm and status indicator Low field strength - no affect on pacemakers and magnetic media Detects all metals and alloysTechnical Specifications:Detects:Medium Pistol at10" (250 mm) , 25 cal. at 8 (200 mm) Mini revolver, 22 cal. at 6" (150 mm) Cartridge, .357 at 4 (100 mm) Razor blade at 2"( 50 mm) Hat pin at 1"( 25 mm)Scan Rate:3 to 24 (75-600 mm) per secondElectronics:The highly reliable advanced detection circuitry is housed in a rugged high impact ABS plastic case and detects all metals and alloys.Alarm Indicators:High efficiency piezo electric beeper and multi-function BLUE LED indicator.The BLUE LED indicates the following three functions;Normal Light when the unit is switched ON.Brighter Light when metal object is detectedFlashing light when battery is low.Power Requirement:Ultra-scan works on rechargeable batteries.Low Battery Warning:Low battery is indicated when the LE starts flashing. However the unit continues to function for several hours after the Low Battery Warning.
