Be aware that there is the original Surfmaster PI and there are now two version of the Surfmaster PI Pro. The original Surfmaster PI if set up right will get 8 to 9 inches air testing on a nickel. The first version of the Surfmaster PI Pro will get 10 to 11 inches air testing on a nickel. The 2nd version of the Surfmaster PI Pro will get 12 to 13 inches air testing on a nickel. But I have seem one of them get 14 inches air testing on a nickel. Whites appears to be upgrading the Surfmaster PI Pro when you send one for repair. But I did not know if they do this all the time.

the same as a pulse delay.
The gain is a sensitivity control, and in the case of the Surfmaster PI Pro it's in the final stage of the receiver.
A pulse delay controls the delay period between when the transmitter shuts off, and the receiver turns on. This is not user selectable on the Pro model. You do have a pulse delay on the earlier Surfmaster PI, before the "Pro" model.

I hope you held on to the 14" one.

The one that gets 14 inches on a nickel belongs to a local friend. A lot of people bring their Surfmaster PI to me so I can increase the audio volume. I also check the internal adjustments to make sure that they are correct or adjusted as needed. I have not had a Surfmaster PI for over two years now. Still using my Aquastars because there still is nothing that will match them for depth on gold items!
