What Makes Groundtech Pinpointers Different
Groundtech pinpointers are pulse induction probes built to recover targets fast in the ground that defeats ordinary pinpointers. Most pinpointers, including the popular Garrett Pro-Pointer, use VLF technology that falses and loses depth in saltwater, black sand, and highly mineralized soil. Groundtech runs a pulse induction (PI) core that ignores those conditions and stays locked on metal, so you keep full sensitivity at the surf line, on iron-rich sites, and in mineralized gold ground. This collection carries the handheld Groundtech IQ Pointer and the Groundtech IQ Detect scuba probe, both engineered as the recovery companion for any detector or 3D ground scanner.

Built for Saltwater, Black Sand, and Mineralized Ground
The Groundtech IQ Pointer weighs just 7.5 ounces and is rated IP68 for full submersion to 9.5 feet, with an internal Dive Lock that stops water pressure from triggering the buttons on a dive. It auto-calibrates at power on and re-balances with a single button press, so it stays stable as conditions change. A 360-degree detection tip and a 6-level LED signal bar guide your hand precisely to the target, and three sensitivity levels let you dial the probe to the site, from low for saltwater and highly mineralized ground up to high for maximum reach. Choose audio, vibration, or a silent vibration-only mode for quiet night hunts, and light dark holes with the built-in flashlight. This is why a pulse induction pinpointer earns its place in a beach and water kit where standard probes struggle.
Pairing Your Pinpointer With the Right Gear
A pinpointer is the link between your machine and your target, so it works best matched to the rest of your kit. For dry-land hunting, compare the full range in our metal detector pinpointers collection. Because Groundtech runs pulse induction, it pairs especially well with our beach detectors, waterproof metal detectors, and mineralized-ground gold detectors. If you want another pulse induction option, see the underwater probes from Treasure Products. To build a complete setup, browse our full range of metal detectors, and if you run a deep-seeking system, our Groundtech buyer's guide covers the 3D ground scanners these probes were built to support.
Frequently Asked Questions
Are Groundtech pinpointers waterproof?
Yes. The Groundtech IQ Pointer is rated IP68 and fully submersible to 9.5 feet (3 meters), with an internal Dive Lock that prevents water pressure from triggering the buttons underwater. The IQ Detect scuba probe is built for full submersion and scuba use. Always confirm the O-ring is clean and the rear cap is fully tightened before diving, and never open the rear cap while the unit is wet.
Why is a pulse induction pinpointer better for saltwater and black sand?
Most pinpointers use VLF technology, which is thrown off by salt and ground mineralization, so it falses, chatters, and loses depth exactly where the good targets are. A pulse induction pinpointer like the Groundtech IQ ignores mineralization and salt by design, so it stays stable and keeps full sensitivity on wet saltwater sand, in black sand, and on iron-rich mineralized sites.
What is the difference between the IQ Pointer and the IQ Detect?
The IQ Pointer is a handheld pinpointer for precise target recovery in the hole, on land or underwater. The IQ Detect is a compact pulse induction detector built around a fixed 7-inch coil, which gives it a wider search area for underwater and scuba hunting. Many water hunters use the IQ Pointer for everyday recovery and the IQ Detect when they want more coverage on a dive.
How is the Groundtech IQ Pointer powered?
The IQ Pointer uses a built-in 1050 mAh rechargeable lithium-polymer battery that charges over USB-C in about 10 hours. There are no disposable batteries to replace, and a Lost Alarm sounds and flashes after 3 minutes of inactivity so you do not leave it behind in the dirt.
Will a Groundtech pinpointer work with my metal detector?
Yes. A pinpointer works alongside any brand of metal detector or 3D ground scanner. You use your detector to locate the target area, then the Groundtech pinpointer to zero in on the exact spot before you dig, which speeds up recovery and protects your finds.
Does the IQ Pointer have a silent mode for night hunting?
Yes. Alongside audio and combined alerts, the IQ Pointer offers a silent Ghost or Stealth mode that signals by vibration only, which is ideal for quiet night hunts or permission sites where you want to keep noise down.
