You don't really lug a 19" coil around to find smaller nuggets. 0.1gram would be plenty small enough for me:GoldProspector said:I played with the gpz19 coil yesterday at the Perth 4WD show. bit heavier than the gpz13. guy at the stand was concerned with the gpz19's ability to detect the smaller nuggets. time will tell. not long to go now. :lol:
When using Normal Ground Type (in milder soils) Ive actually been able to run a higher Sensitivity setting. I just couldnt believe how smooth it was running for such a big coil, and I blooded the coil with its first piece after a short time, a very small flat piece of about 0.1g which proved that the big coil hasnt given up much sensitivity."
