It doesn’t matter to Chinese what they produce, especially if you are ready to buy it. Here is, for instance, a new product 2018 – Chinese-made fake Teknetics G2 with a… Garrett 8.5×11 DD coil. Isn’t it cute? The package also includes the Garrett locking collars and a strengthened armrest (counterfeit parts). Some hybrid fake, eh?
For your reference: A China-made TX 850 (Tianxun) machine is a counterfeit Teknetics G2 / Fisher Gold Bug DP. Comes with an 11 DD coil (a fake Garrett 8.5×11 PROformance DD). New in 2018. The purchase price starts at $140. The ordinary retail price of the TX 850 is $170-$180.
