When to use the Discovery 13
For a White's Coinmaster Pro owner, the Discovery 13 is a way to sweep open, fairly clean ground in wide passes. A 13 inch Double-D coil sweeps a broad path, which pays off where finds are scattered thinly. Around heavy iron or in brush, a coil this size is harder to steer and tends to hear several targets at once, so we would go back to the stock coil there. Walk in lanes that overlap by about half a coil width, and expect the coil size to help coverage first; any extra depth depends on the soil and the target. Our metal detector coil guide explains how coil size and type trade coverage for separation.
MarsMD built the Discovery as a well balanced, reliable coil for a wide range of search tasks, and says it gives a considerable depth increase and more ground coverage than standard coils. Its weight starts from 520 g (18.3 oz) and can be higher depending on the detector version. The coil is waterproof and shielded against electrical interference. The outer shell is high impact resistant, UV protected plastic filled with a high quality epoxy resin, the coil mounting bracket is extremely robust, and a cable strain relief keeps the cable entry watertight. The connector screws on.
