[QUOTE="XLOOX, post: 631228, member: 16174"] regardless of GB on or off, set pulse delay to 10us for small gold and for small coils 8" or less. for coils above 12" set pulse delay 12 or higher as needed to settle her down. always turn gain up as far as you can whilst maintaining stable response. youshould be able to run 6 gain anywhere and upto 8 in medium ground. above 8 prob need mild ground. start up with GB on, All mode, 6 gain ,15 delay and threshold gentle hum. adjust GB to give silent bob. adjust gain up until unstable then back off a little. redo GB swing and see how you go. only adjust delay up further if have +12" coip and still not stable.
