Hello forum lurkers, its been a while since I posted here but I make no apology because its been a while since I had time to do much of anything outside of the day to day running of a retail business. The reason I'm posting today is because I was forced to defend myself on an Aussie forum after posting up material on our The Outback Prospector FB page OBP FB page so now feel this forum deserves some of the information because I would prefer to spend my online time here than anywhere else.
The GPZ19 coil is the subject of scrutiny at the moment and for good reason, namely that it offers the full depth potential of a very powerful metal detector. I know this is not an ideal scenario for a lot of detectorists who work in very hilly scrubby terrain but for a lot of people its announcement and pending release is definitely raising the pulse levels. I've been exposed to large coils on the GPZ tech for a long time now, with the first coils I used being hand built heavy monsters. I was also very fortunate to have been involved in a major alluvial gold discovery around the same time so benefited from regular deep gold discoveries with these coils on a regular basis, this then fast tracked my understanding of SuperD and ZVT when exposed to deep targets outside the range of other tech.
At this stage I've been asked to write up some material on my experiences with the large coils so will hold off on going into too much detail here but keep an eye out once these go mainstream, also please bear in mind I now own a retail business that relies on my personal information being exclusive to its success so need to focus on whats good for my business.
The main advice I can give for successful large coil use with the GPZ 7000 with GPZ19 is,
The deeper the gold the larger the range of controlled coil sweep required to assist a suspect target signal to be recognizable from ground signal
Conservative Sensitivity and Volume settings
Careful coil control
Comfort when swinging the coil
Quality clean audio
Targeting the right places to detect
I'll post more to this thread when I have time over coming days.
