But in other test crypton OBMD1 detect 70 years old target from 10 meter .
Morgan I saw your movies in youtube ,please show in movie Alonso PD , from how much distance can detect 1.5 volt batt, short circuit? . please use wire long 30 cm.
Regards .

1,5V spark

ALONSO PD, 60cm

OBMD-2 , 40 cm

PDK-2 ,2,20m

the spark distance only means sensitivity to that frequency, more important are the field tests.
