The 13 to 15.7kHz frequencies are intended for general use, they provide good sensitivity to a wide range of targets, the higher frequencies will take the Deus to another level. You will instantly notice the enhanced sensitivity and the ability to find small targets that have previously been difficult or impossible to locate when searching mineralized ground with competing devices. Aside from the ability to detect through mineralized soil, the HF coils will enhance the target signature from weak - low conductive targets or even highly conductive targets. Due to their shape or construction (thin or wired), many of these signals are beyond the reach of conventional detectors. Now items such as open rings, earrings, fine bracelets, wire framed artifacts, gold nuggets, intricate items, small coins, thin coins and coins on edge will be easy to locate!This new High-Frequency coil weighs less than 12.5 ounces and is equipped with the latest high capacity lithium battery (850mA). The new battery is situated in the lower stem and can be replaced in seconds, this is a bonus especially if you are working in a remote area far from a power source. Includes coil, coil cover, lower rod, battery, and coil bolt hardware.
