Deep earth gold scanner GF2, underground gold detector machine

Features:
The Gold Finder GF2 is a high performance multi-purpose professional metal detector. It utilizes the latest advances in electronic technology, and its functional design represents the leading edge of engineering.
The GF2 is easier to learn than other comparable metal detectors. Its combination of light weight and balance provides comfort unmatched by any other detector in its price range. Its most popular uses include coin shooting, relic hunting, and gold prospecting.
Large LCD Screen with Target Identification Display
Straightforward Menu Driven user interface, menu system is always visible
Selectable Tone I.D. - GF2 offers 6 different tone modes for Target I.D.
All Metals Mode: First derivative (single-filter) motion
Discrimination modes for searching in trashy areas. Second derivative (two-filter) motion, with selection of target identification tones and sampling methods.
Ground Cancellation: Trigger-Actuated F-GRAB Instant, Tunable Ground Cancellation
Continuous Ground Monitor: Bar-Graph Readout of Ground Mineral Classification
Magnetic Mineralization Volume Readout
Trigger-actuated target: pinpointing with variable audio pitch
Visual Target I.D: 0-99 plus eight target category indicators
Mineralization Readout: ground cancellation phase 0-99, and mineral concentration bar graph

B-AXIAL Search coil - DETECT AT THE NEXT LEVEL
Part of the "Secret of Success" is the revolutionary NEW BIAXIAL™ search coil. Here is a totally new search coil that penetrates all soils deeper than ever before. Soils that resisted other detectors and other search coils, such as high ironmineral soils, conductive soils and saltwater beaches are now able to be penetrated to give up all their hidden treasures that have yet to be found. This dynamic innovative 11inch Open Frame Biaxial Search coil is super sensitive and detects coins to 15 Inches, and as a BONUS the screen identifies your target (coin, ring etc.) and Tone I.D. also identifies your target. You know what's under the coil BEFORE you dig!
