Hi I'm the distributor for Detech in Australia.
We have been having great success with the Detech range of coils.
Australian prospectors have been keen to purchase these competitively priced coils.
And have most certainly given us positive feed back on the build quality and performance.
The range of coils have been extensively tested in the Australian gold fields, all new coils are tested here before we release them.
Most of the feed back is on how sensitive the coils are and how they go about there job so quietly .
These are robust coils 100 percent waterproof and very resistant to bump or touch sensitivity
We've had great customer feed back
The Detech range is still evolving
Hope this helps
