AKA Selenium Pro

The Selenium Pro is the expanded version of AKA's Selenium pulse induction detector, put together for professional treasure hunters who want maximum depth on large buried targets. It keeps the Selenium's low-frequency PI electronics and its pair of coils, a 17-inch mono coil for general searching and a one-metre square frame coil for wide, deep scanning.

The main addition is a 12-metre universal cable. AKA states that this cable can increase detection depth by up to 40 percent compared with the standard set-up, which effectively lets the operator work with larger search loops for very deep objects. The Pro bundle also includes quality headphones, a rechargeable battery with charging cable and adaptor, an adjustable telescopic shaft, carrying case, coil protector and a professional operator vest.

This is a specialist instrument for locating big metal objects such as containers, caches and buried hoards in open ground, not a coin or gold-nugget detector. Any depth gain depends on target size and soil conditions, so the 40 percent figure should be read as the manufacturer's claim. For Pakistani teams doing serious deep-search work, it is AKA's most complete Selenium package.
