My Experiences With GPZ 19

[Jonathan Porter]

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.

Thanks for the info JP.  How did u find pin pointing and nugget recovery with the large coil? Any advice there? Or just dig big holes?   Cheers. JG

Those are some awesome lumps of gold JP - thanks for posting!

Thank you for the time taken to post JP.

I collect my 19" on the 14th and will head out to some patches as soon as there is a few cooler days strung together. I was hoping you might(when you get time) go into more detail on your first point. "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"

 

That's some nice pieces of gold you found congrats!

Yes, absolutely incredible gold! Must have been super fun and exciting to unearth! Thanks for sharing. :-)

JP thanks for posting, some great gold there. Soon the GPZ 19 will hit the shores of the USA. I can hardly wait for mine to arrive in the mail, hoping its sooner than later. Even if it gets only 10% greater depth, it will put me on the gold again. 20% or even 30% more depth, even better.

Good report JP, one question have you noticed the Zed chewing more battery with the larger coil?

[Des D]

I'm sure ML would have factored in the draw down drain of the larger coil, but large coils can draw current faster especially if ground noise and false signals and interference create a lot of actual 'noise' Each 'noise' causes drain.

Maybe that's why ML have introduced the New Mini 3 hour battery to allay drop down in the field causing a shut down of search time? (I'm not sure if this battery is an actual New Product and available at this time?)

 

If I was using the set up, I'd ensure any 'unwanted Functions & Options were Off > thereby saving Power

(just realised this New battery is for the GPX and not the GPZ...Duh!)

Put a CTX battery on a GPZ and you'll get about 3 hrs
