Pulse induction for salt water
The IQ Detect runs a pulse induction circuit, which Groundtech lists at 675 Hz, and Groundtech describes it as built for superior performance in underwater and saltwater environments. Detection covers 360 degrees around the head. The fixed 5.5 inch (14 cm) coil is sealed into the unit, so there is no coil cable to snag or flood.
Balancing, sensitivity and alerts
The IQ Detect calibrates itself when you switch it on, and a short press of the power button balances it again to the conditions around you. Three sensitivity levels cover different conditions: Low for indoor use or highly mineralized and saltwater ground, Medium as the standard setting and High for maximum reach. The 6-level LED signal indicator climbs as you close in and lights all six when the coil is centered over the target, and you can choose audio, vibration or both.
Dive Mode, Ghost Mode and the flashlight
Groundtech rates the IQ Detect IP69 and submersible to 30 meters (98 feet). Dive Mode locks the buttons so water pressure does not trigger them on a dive, and Ghost Mode switches to silent, vibration-only operation. A built-in flashlight helps in dark water and holes, and if the IQ Detect sits idle for 3 minutes, the Lost Alarm sounds and flashes so you can find it. We would keep it on the security lanyard on every dive. For land and shallow water recovery, Groundtech also makes the Groundtech IQ Pointer.
Care
Never unscrew the rear cap while the IQ Detect is wet or submerged. Before every dive, check that the O-ring is clean, grease-free and intact and that the rear cap is fully tightened. Rinse it with fresh tap water after use in salt water or mud, and keep thinners and harsh chemicals away from it.
