X-Terra 705 Universal Detector

X-Terra 705 Universal Detector – A versatile all-purpose detector capable of all types of detecting, from coin & treasure to relics, beach and even gold prospecting.


VFLEX Technology – Allows you to change the frequency simply by changing coils.

Two Coils

  • Standard 7.5 kHz Concentric coil: waterproof — suitable for beach and riverside detecting.
  • Standard 18.75kHz Double-D elliptical coil: provides effective depth and ground coverage, plus the coil’s high frequency is extremely sensitive and perfectly suited for finding small pieces of gold.

Target Stability -Allows for precise, solid responsiveness in high-trash areas enabling you to efficiently and effectively search sites with a high concentration of junk.  Also a great coin detector with highly accurate discrimination and numeric target identification.

Four Preset Detecting Patterns – Customisable and includes All-Metal Mode.

Prospecting Mode – The specialised Prospecting Mode has improved sensitivity making the detector more sensitive to small target signals. The Prospecting Mode can be used in highly mineralised, ‘difficult’ areas. The Prospecting Mode is ideal not only when searching for gold nuggets but also for small relics and some types of jewellery.

Adjustable Iron Mask – Designed for Prospecting Mode. This feature allows you to find desirable targets lying close to ferrous metals.

Automatic & Manual Ground Balance -Includes Tracking and Tracking Ground Balance Offset adjustment.  This creates a performance advantage in certain areas such as wet/dry sand transition and hot rock locations, by setting the balance slightly positive or negative.  True automatic Ground Balance eliminates false ground noises so you can hear elusive small gold signals.

Pinpoint Modes

Two Pinpoint Modes:

  • Auto
  • Sizing

Depth indicators update continuously, even in Pinpoint Mode.

Noise Cancel – Reduces interference.

LCD Display – Positive transflective LCD display providing a back light only in dim light conditions enabling better screen visibility in poor lighting whilst saving battery charge in well lit conditions.

Lightweight – Lightweight, balanced design (1.3 kg).

4 X AA Batteries – Runs on 4 x AA batteries.

VFLEX uses state of the art digital electronics to enhance standard single frequency detection technology. This has the advantage of providing dependable performance and improved immunity to outside interference. VFLEX technology also has an added advantage that changing the detector’s coil also automatically changes the detector’s operating frequency. This means that an X-TERRA detector can operate at different frequencies allowing the detector to be easily modified to suit different detecting conditions.

VFLEX provides increased detecting performance with perfect sine wave transmission, an in-coil signal booster and coil selectable transmit frequencies.
