PSB7-PRO Spirit Says It’s Good If You Have The Mind For It

8/7/23 - After 2yrs of research and development, we are pleased to officially release the New PSB7-PRO Frequency Sweep Device in the USA. I appreciate everyones patience as I worked hard to bring this very special product to fruition.

I’m sure this sounds a bit loud and irritating to many of you. But it’s a great way to practice my hearing. Keep in mind that the sweep sound is 3X normal. A response in 1 device is overwhelmed by the sweep sound in the other 2 plus it’s own noise which makes listening more difficult
