- 지하에 있는 돈 박스, 동전 궤 등의 탐지시 아주 유용한 장비입니다.
- 보통의 금속탐지기로는 측정이 불가능한, 각종 철제 물체를 탐지할시 가장 적합합니다.

- FX-3의 깊이는 아래와 같습니다.

작은 포켓용 칼 :         20-45cm
총검, 칼 :                  30-60cm
나무통감싸기(링) :     35-90cm
철(돈) 상자 :             58-152cm
포탄 :                      100-130cm

최대탐지거리 1미터 - 3.5미터 탐지가능 (금속의 크기 및 금속의 종류에 따라서, 탐지 환경에 따라서  다양하게 나타남) (정확한 것은 전문상담요망)

 Fisher's FX-3 Ferro Probe is a differential Induction Magnetometer designed
to locate iron and steel relics, property markers, pipes and other large ferrous
objects buried beyond the reach of ordinary metal detectors.
Two sensors respond only to the magnetic field of ferromagnetic objects,
ignoring all other materials (copper, aluminum, brass, etc.).
As a target is approached, the VCO (Voltage Controlled Oscillator circuitry
responds with an increase in pitch and volume then nulls directly over the target.

Search with extreme sensitivity: The FX-3 s extremely sensitive to objects with
large surface areas, highly magnetized objects and long objects buried vertically.
Large or small, if it's ferrous, the FX-3 was designed to find it.

Locate Relics and Artifacts with ease.
FX-3 Probe is dynamite in finding Civil War relics from the smallest uniform buttons
and musket balls to the largest belt buckles and box plates.
This probe can get into places detector coils CANNOT reach.
Search deep into thickets, trench formations, even between rocks!
Find smaller targets than two-box detectors but has more depth than standard search coils.
