| NEL's exclusive product is a dual frequency reel. The Tornado coil is NEL's most famous coil. It is the "golden mean" for searching for coins, treasure and artefacts in military battlefields anywhere, now with the ability to switch frequencies. The coil is unusually light for its size, at just 570 grams, making it easy to search all day! The slow-wire coil is great for detecting not only large and medium targets, but also small targets weighing less than 1 gram, at depths unreachable with any standard coil. The frequency selection allows the detector to be optimally tuned for different search conditions. The &Scaron™ coil exceeds standard coils in depth by 25% (compared to a standard 10 " coil) and in ground scanning area by 20% (compared to a standard 10 " coil). Recommended as a replacement coil. The reel is fully waterproof, the housing is filled with epoxy resin and additionally has a black protective coating used to protect offshore yachts and boats, which allows searching with the šo reel without the use of plastic protection. The reel is recommended for outdoor use. The coil copes well with high to medium mineralisation of the soil. Recommended for professionals and amateurs!
