When to use the Discovery 13

Garrett ACE owners who spend most of their time on open, lightly littered ground are the natural fit for the Discovery 13. 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 change to a compact coil there, such as the Mars Sniper 10 x 6 we carry for the ACE 250 and ACE 350. 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.
