[QUOTE="XLOOX, post: 631307, member: 16174"] OldHand came up with the idea of using a 6:1 vernier mech on the GB pot. I tried it & liked it & told Karelian who told the guy in the USA who now does the conversions. [url]https://www.prospectingaustralia.com/forum/viewtopic.php?pid=553435#p553435[/url] Nesral then suggested a multi turn pot for both the GB and the threshold and I tried it & can attest that they makes a huge difference to usability. [url]https://www.prospectingaustralia.com/forum/viewtopic.php?pid=573713#p573713[/url] The multi turn pot for GB doesnt deliver any benefit over the vernier mech but is 1/10th of the price. If you can solder you can do both mods yourself for about USD 20. [/QUOTE]
