X-Terra 505 Universal Detector – Looking for more performance? The X-TERRA 505 is an improved treasure detector with all the features of the 305 and more.


VFLEX Technology

Coil Compatibility – Compatible with low frequency (LF) 3kHz coils as well as medium 7kHz and high frequencies 18.75kHz. The LF coil option is ideal for hunting large, deep targets. All X-TERRA Coils can be used on the X-TERRA 505.

Target IDs – Choice of 1, 2, 3 or 4 Tone ID’s plus Multi-tone Target ID (19) response options increasing your flexibility in deciding how target signals are represented.

Three Detecting Patterns – Three preset detecting patterns that can also be customised, plus All Metal mode.

Discrimination – Larger discrimination range allowing for finer discrimination of high conductive targets.

Ground Balance – Increased Ground Balance capability, range now (0 —50), allowing the user to adjust to ground mineralization.

Pinpoint Mode -Fast recovery Pin-Point with variable tone and graphical indicator.  Depth indicator updates continuously, even in Pinpoint mode.

Threshold Adjustment – Threshold adjustment, with a range of -5 to 25, allowing the user to set threshold to level where slight variations from either very small shallow, or very large deep, targets can be noticed.

Noise Cancel – Increased Noise Cancel range, now 5 manual settings, allowing greater choice of detecting channel. Increased Target Volume.

Volume Adjust – Increased Target Volume Adjust range, now (0 — 30), allowing better target response.

Lightweight – Ultra lightweight, balanced design (only 1.3kgs).

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.
