1.Communicates with vibration & light When a target is located the Vibraiking750 signals with pulses of vibration and flashes of bright from white LE.D ) 3. Detection depth stability - (New Advanced circuitry maintains detection distance throughout the life of the battery) 2. Pulse Induction Technology (PI) - (Allows hunting in salt water or in any type of soil, including black sand) 4.Target distancing - (The pulses of vibration increase in frequency as the probe approaches the target precision pinpointing) 5. Automatic tuning - (The state of the art microprocessor control design requires no adjustments of any kind)
