Yes, obviously the Threshold, standardized in all modes and frequencies. 0-being off, and then gradual increases in volume for each notch, the loudest being 10. Please emphasize stability. Also ensure that it is playing over the wireless headphones just as it does over the detector speaker.
Please verify that VDI readings from targets, are standardized through all modes, and as you change from different frequencies. I had a problem with a high conducive coin giving a higher value after scrolling through all the frequencies an then back to M2, from initially turning it on, but that was also with v1. 06.
Please see if you can figure out why the detector screen will just freeze up to where none of the buttons respond, except for the power button, which when pressed for around twenty seconds the detector finally turned off. It did work fine again when I turned it back on, and has only happened once.
Thank you for such a great detector.
