Titan 400 Smart

The GER Detect Titan 400 Smart is a multi-system search kit whose most useful component is also its most conventional and the only one you can verify yourself: a VLF electromagnetic metal detector running at 10 kHz with a 30 cm search coil. That is proper detecting hardware — you sweep it, it responds to metal under the coil, and the VLF screen gives you ferrous and non-ferrous indication, adjustable sensitivity and an iron-elimination setting so you can walk past nails and bottle caps. At 10 kHz with a 30 cm coil, realistic field performance is roughly 25 cm on a coin-sized target and around a metre on a large buried mass, depending on soil, mineralisation and how the target sits. GER Detect quotes up to 3 m for the VLF system; that is a manufacturer figure. The coil detaches from the shaft, and the unit switches automatically to the matching system the moment a different sensor or antenna is fitted, so there is no mode menu to work through in the field. Beyond the coil, the manufacturer lists three further modes driven by the plug-in sensors and the two antennas supplied in the case: a long-range sensing system for which GER Detect specifies a front range up to 3,000 m and depth up to 25 m, an ionic-field system aimed at long-buried caches, and a voids detection system for cavities. These are long-range locator technologies — we list them exactly as the manufacturer describes them rather than as measured performance, and our honest advice is to buy the Titan 400 Smart for the VLF system you can test, and treat the remaining modes as supplementary survey tools. The control unit itself is well built: a 98 × 57 mm full-colour touchscreen at 480 × 270 px, a six-language interface (German, English, French, Italian, Spanish, Arabic), a 27 Wh internal lithium-ion battery rated by GER Detect at about 10 hours, a dynamic speaker covering 350–5,500 Hz at 84 ±3 dB, and rechargeable wired plus Bluetooth headphones. The unit weighs 595 g and the coil 675 g, with the complete kit in its 620 × 430 × 200 mm protective case coming to 6,620 g. GER Detect states CE and ISO 9001 certification, and the detector ships with a two-year warranty.
