Looks like Codans newest offering is a flop, page-36

Underground Wifi? Underground coms works at 150 KHz and below, hardly enough frequency spread for WiFi....lol I did mine coms at 15 KHz 15 years ago and point to point data was done using repeaters at 10 Ghz inside the mine. How I love watching the rediscovery of the wheel!

As for the new detector, it is a flop, sounds off on ground depressions, has no extra depth, only gets small gold via OOO coil design AKA DD derived., The GPZ will be a short lived "Innovation"

Ask them why they lost certain defence contracts? If they do not answer you can always ask the Chinese.

It pays not to lose or misplace a laptop. Codan needs to pull its socks up.
