The White's TDI metal detector features full balance ground control to quickly balance out the iron mineralisation of hot rocks, black sand and other tough ground conditions. The adjustable pulse delay allows settings from 10ms for finding gold nuggets to 25ms for relic, coin and beach hunting. The 3-way target conductivity selector allows the user to distinguish between possible targets. The TDI from Whites also has a frequency control to help when searching near power lines, microwaves or other environmental interference. The TDI comes fitted with a waterproof 12" spider search coil.

White ’s opinion
FINDING GOLD WAS JUST THE BEGINNING!
TDI was originally designed for prospecting; now optimized for exceptional performance for relic, beach, even coin hunting.
Professional-level ground-balancing, pulse induction detection. Unlike any other metal detector on the market today, the TDI is capable of remarkable depth and extreme sensitivity in the worst grounds.

Optional Extras

	Carry Bag- A carrying bag will help with much more than just carrying your detector. Stop it from getting scratched, or dirty and help to keep the value of the detector. There’s nothing worse than trading in an old machine for less than you would like because of a silly scratch or mark.
	Mini Shovel- Lightweight mild steel and fibre glass combination. This is an ideal utility trowel to have when detecting. The Mini Shovel has a wide blade which offers much more versatility and ease of use than the smaller trowel blades traditionally used by detectorists.
	Handbook - The Handbook for detectorists is a treasure chest of information about metal detectors, techniques, sites, finds and well kept secrets. Gert Gesink the Dutch author spent 3 years putting all of his knowledge as detectorist, metal detector distributor and writer together in one book.
	Stabilisation Bracket- This White's coil stabilisation bracket will help prevent the coil from flopping on any White's metal detector. It is especially useful for use with a larger coil or on older detectors where wear and tear are evident.
