2.American Teknetics

One of the third largest brands in the United States, of which the largest brand in the United States is BountyHunter Bounty Hunter. Teknetics was founded in 1983 and became part of FirstTexas metal detection products in 1989. In this era, teknetics has become the hottest brand; engineers began to redefine industrial performance standards in the early 21st century, and now have Teknetics handheld metal detectors.
The advantage of Teknetics in the United States lies in the origin of the United States. However, Tekneticse in the United States has a fatal weakness: its in-depth exploration, inaccurate positioning, and environmental influences cannot exclude all interference. For the treasure hunt, this is a fatal, and the American BountyHunter bounty hunter is relatively backward in technology. In the United States market, BountyHunter bounty hunters will also choose more for treasure hunters who pay attention to discrimination and accurate positioning. Teknetics in the United States has been ranked among the top three in the US market. In 2013, it ranked third in the United States after BountyHunter and Garrett Garrett.
