When to use the Goliath 15
Large, open ground with sparse targets is home turf for the 18.75 kHz Goliath 15. A 15 inch coil asks more of your arm over a long day, and where junk lies close together its signals tend to blur into one another, so we would not make it the everyday coil for busy, trashy sites. The Mars Discovery 13 is the other Mars size we carry for the X-TERRA. Keep the coil low and level, overlap each pass, and treat any gain in depth as something the ground decides. Our metal detector coil guide explains how coil size and type trade coverage for separation.
MarsMD designed the Goliath for detection depth and the widest scan field it can give, and says it is most efficient on large open areas clear of thick vegetation. Its weight starts from 580 g (20.5 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.
