They used to have a forum in the manufactures area, which appears to have been deleted. They had some big hype a few years ago. Their quality was not very good. I watched plenty of reviews of the Quest when it first came out. Most had problems with them. On guys coil cable was crimped and shorted and he destroyed the machine at the end of the video. They were then sued by Teknetics since the Quest intruded on the T2 programming. BigWaveDave won their contest and was given a detector that has become a dust collector.
