The Class D amplifier was a great idea but the problem was increased interference when using a large coil, Class A B amplifiers that use common amplifier topography generate high levels of hiss type background noise and this is particularly bad using metal detectors with low threshold volume. We came up with a high quality class B design that has next to zero hiss and generates no extra noise. It only draws 5 milli amps with no input and thus has no noticeable effect on battery drain. This is a winner, to be released soon.

Any news on the new booster Woody?.... still rocking my original kit booster+battery rig, but new is always better :)

Yes its done, I have not really started to advertise it but it runs headphones and speakers and the sound has no hiss and has its amplitude controlled so it does not blow out your ears, also the booster has voltage display and one switch turn off for the booster and the detector so no more flat batteries from forgetting to power off both.
