  1. Wowsers nice chunk!! Knowing the country you work that piece could go anywhere from 8 to 16 ounces? I use Manual a lot if the conditions allow or call for it. Outright depth is always achieved by using a fixed or manual ground balance, in the case of the GPZ and its stupidly linked Quick-Trak to the ferrite calibration this means going in and out of Manual and Semi-Auto modes via the menu. If your lucky enough to work in an area where X signal is not an issue then obviously you could use the QT button and speed things up. So yes in homogeneous ground where the GB is not altering
  2. This is the first gold detector release in 20 years that I’ve been heavily involved in helping to develop were I’ve had NO contact with marketing on any level. Right now I feel like a dinosaur that’s gone well past its used by date, I keep looking up for the comet strike!!! 😅🚫 In some ways it’s refreshing but in others it feels akin to driving in traffic with a blindfold on. 😬 😱
  3. I have one phrase in answer to all this, “Range of Motion”. Every target has its optimal coil movement which is coil height, coil windings orientation and coil speed relative to Ground Zero. You can call the speed “speed dependant” if you like as we are almost always talking about ‘Motion’ detectors. The range of Motion is dictated by the ‘lead in and tail out’, swing speed is dictated by ‘Range of Motion” distance, ground conditions and size of target relative to depth. Once you get the “Range of Motion” worked out (that’s the distance measured between the start of the ‘lead in’ through
  4. There’s enough user controls on the 6000 to keep us all busy, finding out whats going on under the hood and then using that to good effect is half the fun.
  5. I agree with just about everything you are saying as well as others in this thread so my comments are just my thoughts on the matter and not written in stone or anything like that. 🥴 The rest that follows is not directing entirely at the quotation but your comments created a desire to put forward my POV.😁 Sensitivity is very important to wring out an edge of detection target signal for sure but it can also kill faint signals if the control is overused. A good detectorist’s brain can get very good at picking out a signal from a busy background, the most powerful add-on to any detector is Y
  6. 200 amps of lithium should be OK even for 2 compressor fridges, just have a decent charger and a genie as a back up if the weather goes south on you. WA in winter in the Eastern Gold Fields the day times temps don’t get much above 24 most days so the fridges are very effecient, night times go down to minus so they cycle less frequently. But there can be a lot of cloud cover at times so using the generator is a lot more effective to keep things topped up rather than having lots of solar panels scattered all around the camp running the risk of wind blowing them around and damaging them.
  7. Having lots of battery storage is great but it’s no good to you if you can’t put power back into the system. This is not a reflection of any of the above mentioned systems just my personal observation based on many years of off the grid living when out bush prospecting. Lithium is amazing because the batteries are lighter and you can use 80% of the capacity, but when the system gets down you need to put the energy back in so plenty of solar is the answer. Whenever cloudy weather appears I always start using my generator for an hour at night and an hour in the morning to keep the batterie
  8. Do you mean the GS 15000? GS 15000 Owners manual My first machine was the GT16000 which I bought in 1987 the year I turned 20. 😎 GT 16000 Owners manual
  9. I’ve owned a lot of detectors over the years, Whites Vsat, Garret Infinium, Gold Bug II, Nokta etc etc and have used a lot of the others. But in Australia I can make a good living with ML machines and every machine that has come out has easily paid for itself as well as paid me to use it. The ML machines I did not like over the years was the GPX 4000 because it lacked SETA, its only saving grace was the Sensitive Smoothing timings in noisy ground, the GP extreme and GP 3000 because of their too fast ground tracking (in homogeneous soils they could track out a deep target before you even
  10. Ditto not enough for me too, not enough time to use them all!!🤪
  11. I see this a lot with detector releases, a new machine is touted at being able to do a specific thing and all the comments by others are focused around how their current detector can do “such and such so why go with the new?”. Pie charts and depth % figures just do not cut it in the real world and are so dependant on the user and many other variables. This is why I hate seeing depth comparisons because all detectors are bound by the same laws. As an example I have dug many gold targets down to a depth of 3 feet, this is from the SD 2000 on through to the current day with the GPZ 7000, yet
  12. I’m emotionally involved in this product and am very proud of it.😏 And even though I’m a veteran of many a product release I still find myself feeling the need to defend it, there’s always lots of self doubt during these early stages.🥺 So I’ll make an effort and try not to get too defensive as more information comes to hand and people react to new concepts and ideas.
  13. Did not mean to offend but a lot of your comments are based on presumption. I can see your point and can only say that time will tell.
  14. Rick, for a seasoned prospector your very negative.🥴 Don’t discount the 6000 till you’ve at least tried it. 🙏 Gold Monster AU$1k+, SDC AU$4k+, GPX 5000 AU$4K+, GPX 6000 AU$7k+, GPZ 7000 AU$9k+, there’s still a place in the line up for the SDC, simple switch on and go and easy to learn.
  15. SDC is MPF, the timings on the SDC are what is known as ‘narrow band width’. The GPX6k is a ‘from the ground up’ totally new design PI. PI and ZVT are two different animals. For outright depth on bigger gold go ZVT every time. Currently for nasty salty ground go SDC MPF with its depth limitations. The moment you design wide band width timings on a very early sampling PI you come up against salt/conductive signals. ZVT is also prone to salt/conductive signals. You will note the inclusion of a DD coil with the 6K, not hard to come up with a correlation as to why that is a standard in the US
