The Vibra-Quatic 2 is our newest designed pinpointer that signals with vibration and light. This any environment pinpointer is great for divers, even when wearing gloves.

The large 2 inch detection tip means deeper detection depths and more sensitivity to large objects. No push button switches. Instead it uses our unique tilt on & off design.

• Pulse Induction (PI)
• Tilt on & off
• Communicates with vibration and light
• Automatic Calibration
• Low battery alert
• Waterproof - Submersible to 100 feet (30 meters)

The unique sealed design is waterproof to a depth of 100 feet and the self calibrating microprocessor controlled circuitry requires no adjustments of any kind.

The Vibra-Quatic incorporates Pulse Induction (PI) technology. This allows hunting in any environment including grass, mud, dirt, sand, black sand, and fresh or salt water.

Also includes a removable wrist strap with ring for added security.

• Communicates with vibration & light - When a target is located the Vibra-Quatic 2 signals with pulses of vibration and flashes of bright blue light.
• Pulse Induction (PI) - This technology allows hunting at the beach in salt water or in any type of soil, including black sand.
• Detection depth stability - New advanced circuitry maintains the unit’s detection distance throughout the life of the battery.
• True Target Direction - The Vibra-Quatic 2 detects at the tip only, not along the shaft, enabling precision target pinpointing.
• Target distancing - The pulses of vibration and light will continue to increase in quantity as the probe tip gets closer to the target.
• Automatic tuning - The state of the art microprocessor controlled design requires no adjustments of any kind.
• Tilt On/Off - No push button switches. The Vibra-Quatic 2 uses a tilt on/off system that eliminates fragile external switches.
• Waterproof - Unique sealed design can be used in almost any environment including fresh or salt water to depth of 100 feet. This makes the Vibra-Quatic 2 an ideal tool for divers.
• Low battery indicator - Built in low battery sensor alerts you when the battery is low and needs replacing.
• Easy battery installation - The standard nine-volt battery is quickly changed without tools. Simply rotate the rear knob and pull out the compression seal to access the battery compartment.
• Solid construction - The Vibra-Quatic’s rugged sealed construction and stainless steel hardware are built to last.
• Belt ring & wrist strap - Includes a belt ring to attach to any common belt clip as well as a wrist strap for added security.
