What our customers say

This is the coil I’ve longed for the Equinox. The extra size allows me to search deeper for high conducting targets in pasture land. It also has the ability of hitting deep hoards out of range of smaller coils.

This is a welcome inclusion to my detecting armoury. It’s definitely a specialist product. 

Where this coil will be a game changer is on clean soils, searching for larger high conducting deep targets. It will also be great when ‘prospecting’ new fields, taking advantage of its increased ground coverage per swing.

In use I’ve found this coil incredibly resistant to EMI. For use over longer periods a harness is a good option to assist with the weight.
