15 METERS DEPTH | CN-D Dual Sensor Technology
“Detect, measure, and locate buried metals and voids seamlessly with your smartphone.”
The Conrad GR-3 Plus is a next-generation underground imaging device that detects differences beneath the soil and allows you to perform highly accurate 3D analysis. It enables you to detect, measure, and locate buried magnetic metals (iron/steel), non-magnetic metals (gold/silver/copper), and voids such as tombs, chambers, and tunnels up to a depth of 15 meters.
Designed to be extremely simple and compact, the GR-3 Plus eliminates cables and heavy batteries. Weighing only 600 grams, the user scans the ground while the collected data appears instantly (in real-time) on the screen of an Android or iOS mobile device via Bluetooth. It is truly a multi-purpose device that operates easily on sandy, rocky, or clayey terrain.

Q: What is the difference between the GR-3 and the GR-3 Plus?
A: The standard GR-3 uses a single sensor system. The GR-3 Plus model features a high-sensitivity dual sensor system (CN-D Sensor), allowing for deeper ground penetration and much higher-resolution 3D data.
Q: Do I need to buy a separate tablet or monitor to use it?
A: No. The GR-3 Plus transfers data completely wirelessly via Bluetooth to your own Android or iOS smartphone or tablet using the free Conrad Analytics Program.
Q: How do I charge the device?
A: The device utilizes a universal 5-volt micro USB charging port. This means you can charge it from the wall, your car, or even a portable powerbank while out in the field.
