VPot has already emailed me and I told him I had a circuit that has no background noise and you can clearly hear the blood being pushed through and I have had sold 30,000 units and none has complained. But he does not listen and has no idea what he is doing.
I have tried to sell these detectors to Doctors, but they don't buy anything. They would not spend $50.00 on something that is ahead of its time, because they do not understand electronics. And this has been the case for the past 40 years.
