NEL Thunder 14.5 x 10.5 inch DD search coil on a metal detector stem

Overview

A coil that combines high detection depth with strong metal separation.

With a slow sweep it responds very well to large and medium targets, as well as small ones — under 1 g. A strong choice for coins, hoards and relics on historical battlefields and anywhere else.

+20–42% depth+32–65% ground coveragevs. stock coil (depending on the metal detector model)

Compatible AKA metal detectors

  • Sorex
  • Signum

Operating frequency: 7 kHz.

Where it works best
Historical battlefields, old settlements and fields with mixed ground, where valuable targets lie next to iron. The elliptical shape gives good target separation and the size gives good detection depth, so you can work trashy spots without switching coils.
Recommended for
Experienced detectorists.

Features
