Hi everyone
i have newly acquired a F1A4 which has had a few mods done to it already. The coil and earphone plugs, volume, threshold and handle GB button.
What I'mm after is the gain mod and the timing and frequency mod. This would bring it up to the level 2 mod I believe and make it quite a good detector. I wouldn't mind doing the battery mod on it and add an external battery. Hope someone on this forum can supply me with some info, pics, schematics on the mods as I cairn'the find much info on it anywhere and I know these have been out and about now for 4-5 years. Look forward to someone's reply. Thanks in advance
