teknetics T2 Very Low Frequency Metal Detector

Mechanical: S-rod with electronics housing mounted on handgrip, 3-piece breakdown, batteries under elbow, 2-way armrest adjustment — forward/backward & around forearm. Searchcoil: 11” (28 cm) open-frame elliptical double-D, waterproof. Batteries: 4 AA, alkaline or NiMH (not included). Weight: 3.5 pounds (1.6 kg) with alkaline batteries installed. Static Balance: force in vertical plane normal to elbow 0.47 pounds (0.22 kg).Varies with adjustment and user’s stance and arm/hand physiology. Dynamic Balance: axial moment, 0.29 foot-pounds (0.39 newton-meters). Varies with adjustment and user’s stance and arm/hand physiology. Sweep Effort: lateral moment 5.2 foot-pounds (7.1 newton-meters). Operating Principle: VLF induction balance Operating Frequency: nominal 13 kHz, quartz crystal timing reference Basic Sensitivity: 5 x 109 root Hertz (detectivity) Lag Coefficient: 70 milliseconds Reactive Overload: approximately 10,000 micro-cgs units (volume susceptibility) Resitive Overload: approximately 1,200 micro-cgs units (volume susceptibility) Ground Cancellation Range: From ferrite to salt, inclusive Discrimination Ground Suppression: combination of second and third order methods ID Ground Suppression: third order Battery Life: typically 40 hours with good quality alkaline, somewhat less with NiMH rechargeable. Operating Temp Range: -4 to +122 degrees F (-20 to +50 degrees
