How to make a convenient and folding metal detector? Using the example of Teknetics T2 (homemade+)

How to pump up your metal detector? Device for pumping! In general, a simple story: one guy in the UK was tired of constantly disassembling and reassembling his Teknetics T2 metal detector for a cop, and his hands and head were growing out of the right places, he sat down and came up with a simple and convenient solution —

I don’t know if this was taken from old furniture, bought on AliExpress, or this stray item is sold in some furniture/gardening/construction stores, but it looks interesting. I just don’t know whether it will play during digging, whether the device will react to the insides of this thing (maybe there is a metal mount and phantoms are possible?), but the idea and implementation are very interesting.

For a good device and a good solution.

What do you think the guy did is interesting? Will this be a new trend for all metal detectors in 2018?
