You also seem to hit more shallow targets using field 2 , ones field 1 does miss.
That is probably down to the recovery and iron bios setting in field 1 on each particular site .
But maybe field 2...
Leave the gb on zero, yep fine it works .
Gb properly to the site your detecting on and it does make a massive difference , try it
Not once for a few mins, try it for a few sessions and you will...
Anyone NOT rolled back to v2 ?
V3 was a huge disappointment for me on my sites , missed many targets that once I switched back to v2 were found.
V3 was slightly more stable, easier to ground...
