  1. I asked Whites how big the coil is and where it was positioned within the shell and I was told that it is as big as the top and the deep part is to house all the electronics. I think it could loose that wart on the bottom as to get the coil closer to the ground then it would be perfect. But saying that the 5.3 (6") is the hottest coil in the Whites range when it comes to tiny targets, and on coins etc it can match the 6x10 (5x9) Lol, for depth in most soils. I really like the 5.3. But that bump on the bottom does help it skim over the ground because it does not have the surface area to slide easily like a larger coil does. EDIT:- another thought that comes to mind is that Whites might have to desensitise the 5.3 because they have hyped up the MX Sports gain system where in most cases people have to use less gain in a lot of places, So that coil might cause people to use even less gain due to how hot it is.
  2. Congrats, that's an awesome result, I think that new machine has relit a fire in you, It's good to see you on a high with a VLF, it's been a long time coming, keep up the good work. J.
  3. Norvic Are you sure it was not a remote control cow and it was not dead it just needed charging, J.
  4. If you want to try and see which one can hit the tiniest bits, set them up with the 5.3 on the MXT and set the SAT to around 2 or 3 and listen to the waver in the threshold in the prospecting mode with the Gain set as high as possible, I managed to hear a bit weighing 0.0002 ozt using those settings, I call that my GPX setting, good luck and have fun. J.
  5. Gerry, There not small nuggets, they're boulders,
  6. G'day Bill, Yes it can be used for prospecting and does quite well but you would be better off using the Whites MXT/MXT All Pro because the MXT has about the hottest ground tracking system ever fitted to a detector and is very sensitive to tiny bits , But the V3i does not use the same system so the long story short is the MXT makes for a better prospecting machine so with the cost of the V3i you would be paying for a lot of stuff that has limited use in the prospecting world, The V3i is a great machine but with so much adjustability it can cause the novice and the average user a lot of brain ache, Where the MXT is about getting out there and getting on with the job, hope that helps, John.
  7. If you check out page 3 Post 51 on this link there is an even better Close up picture of it, J. https://www.prospectingaustralia.com.au/forum/viewtopic.php?id=10345&p=3
  8. Here ya go Steve, have a look at post 48, J. https://www.prospectingaustralia.com.au/forum/viewtopic.php?pid=378203#p378203
  9. Big Thanks Gerry for starting this thread, ya know for once in my life I have found something (Detecting) where there is nothing that I dislike about it, I prefer it if the weather is fine but even when it's not I am happy to be out there, As long as I am swinging and digging then I am a happy camper, Plenty of targets good and bad and good company, what more can a person ask for, John.
  10. I am pretty sure I know my VLF well enough to find anything within it's reach and having the extra coils adds to it's flexibility, I will only use a PI if the ground dictates it, but there are two PI's I would like to add to the kit. J.
  11. Ya welcome JW, if you use it just like you do your GPX where the threshold is the only signal you get and listen for those faint whispers or warble waver the threshold then you are on the right track, I try and keep the SAT as low as possible so the zip zip sound is a bit broader and run the gain as high as I can or use the default relic 2 tone mode and still listen for the AM 3rd tone but it is easier to hear in the prospecting mode. good luck, john.
  12. One major thing that I like about the MXT is that like the GP/GPX design having the rear control box lends it's self to using bigger coils, But alas at the cost of the extra weight, The weight dose not bother me having worked hard all my life, I find the MXT to be a rock solid platform which anyone can work with regardless of their skill level, I bought my first MXT back in mid 2010 and I have 000's of hours using and testing them and I have found that I never end up second guessing or worrying that I have left anything behind, from a prospecting point of view I would only use the 5.3 coil in shallow ground, it will see bits down to 0.02 grams with 0.03g being the norm, the smallest bit of lead I found weighed 0.06 grams or 0.92 grains and being dark in colour it took me about 20 minutes to find it. I like the fact that by using the 3rd tone AM sound that it can add about another 10"+ and more to the depth past the point of where it stops bleeping on coins, And that when fitted with an equal sized coil it can smoke my TDI's and again by using the 3rd tone it will keep up in hotter ground, There are 2 ways you can use the MXT, 1) as a bleep and dig machine, and 2) in cleaner ground by using the 3rd tone or All Metal tone then you will be digging some monster holes where sometimes the only signal you get is a slight rise in threshold, These type of signals you really need headphones like Grey Ghosts/UDT's or Nugget Busters/UDTs, Once you have your ear tuned in to the 3rd tone all it takes is a boot scrape of the ground to confirm the difference between a very deep target and ground noise, A deep target will get louder and ground noise should remain the same or a tiny surface target will move, This type of detecting requires 110% concentration but it works and is the only way to find those very deep targets beyond the reach of other VLF's. hope that helps, John.
  13. The Gold Bug pro can see them bits and is hot on small Gold, the problem lies with the GBP not being as deep as other normal VLF's but it is a hot little machine, when fitted with the 6x4 coil and maxed out and an F-75 or MXT fitted with the same setup the F-75 and the MXT will go deeper, but the Gold Bug Pro has a couple of tricks up it's sleeve like finding keepers that are hidden below other objects, In junk filled sites I would place my money on the GBP over the GM or the F-75 or the MXT, Depth is not what the GBP is about, the fact is it is one of the weaker machines out there but I Guarantee the GBP will make finds where others don't, I love my MXT and it is a brilliant machine but the GBP is a sneaky little devil.
  14. Yeah Fred that's true, there needs to be more working together and an even playing field, because together both parties could work wonders and the knowledge shared would lead to even greater discoveries, J.
  15. Some of the written word in some of the articles looks quite promising but alas things are not quite as rosy In the real world, archaeologists still resent metal detectorists and label us as thieves along with other names unless detectorists are making them look good, and when we donate items to the museums they very rarely list the finds as found by a Detectorist when displayed suddenly we become "amatuer archaeologists" I know when good finds have been made that certain respected archaeologist salt the area with washers to stop people detecting there, I have also seen them do it on national television, I have an area where I know something is there because 7 years ago I kept finding roman and medieval coins where many others had failed so I used google earth and saw shapes/patterns in the ground and I also found roman tiles too, I don't want to stir up a hornets nest because the farmer does not want to know what is found there and he does not want archaeologists coming up and digging up his crops, many years ago there was another ancient find in one of his fields and he lost his field for about 4 months, I know what is there and if I find it then all I can do is bury it deeper, I mapped the place and logged everything with a GPS and I have Ariel photos of it, But I would rather walk away from it, It won't get detectorists any more respect leased of all my self and the valuation committee are too long winded and take for ever, I know that there is an offerings pit there as well because I have found a few rolled up pieces of lead with prayers/curses written on them which the Romans use to write messages to their Gods and they would also throw in coins as an offering in order to bribe their Gods favour. J.
  16. Ooops Sorry I thought we were on the regular pages, I will go and edit my post Sorry about that, J.
  17. Amen to that Steve, Detectors have not really gone forward more like they have side stepped for the last 5 years or so and it has become impossible to be brand loyal, I would like to suggest to the OP to re-read your Nugget Detector recommendations section from top to bottom and then read it again, J.
  18. The TDI SL can match the Pro if you add the power to the input side of things and fit it with a good coil, Before I bought my TDI Pro I asked if they were going to phase them out and the answer was "NO" and in less than 6 months they were gone, Kinda ***** me off when people aren't straight with me, It is a shame because it was a good all rounder and only leaves the GPX 4500 as a good starter kit for anyone who wants a do it all PI that is serious about prospecting, Loosing the TDI Pro has left a gap in the market, and a bitter taste in my mouth.
  19. I agree, Steve H and Chris Ralph were early pioneers of the first model of the MXT and their success rate and the stories told help launch the MXT to almost a cult status, ever since then VLF's have not gone very far if at all, I have made many amazing finds with mine in so called hunted out places, The more I use it the more I learn even after all these years, At the time of buying my first MXT I had about 9+ detectors and when I found out just how good the MXT was I sold the others within 2 months, The MXT does everything that any other machine can do at a more realistic price and it has a proven history at finding Gold. John.
  20. Yep, there is good and bad from both types of tech, I just wish my VLF had the Raw grunt that my older machine has, Although my newer machine is very powerful now I have the coils sorted compared to all others, That old timer has a heap of power and a Velvet Threshold that is rock solid even when flat out, and the use of the GB and the Disc to deal with the ground is dearly missed on modern machines. J.
  21. Yep but mainly it relates to PI machines, In short ground noise = Mineralization or mineralized hot spots, with VLF's it presents much larger issues, With new machines we have fast auto-track etc which deals with the changes but not with the feedback from the ground, It can be dealt with in a number of ways IE Whites V-SAT systems or/and running at a much lower gain but with the Older machines they were far better at dealing with such conditions, Where you could ground balance to help cancel out the ground like you can with newer machines but on the older models you could also adjust the DISC to cancel out any ground noise completely, and also they had a lot more power to the point of what a modern day machine can achieve using a 15" Concentric Coil the older machines can/could do using a 9.5" Coil. When I spoke to a Whites engineer earlier this year he told me that a lot of power was lost when Detectors switched from Analogue to Digital, Because It was the Analogue components that created the Power, where as now it is all done via digital software, Until a person can run side by side tests as I have done comparing the two technologies only then will you see the differences between them, and to be honest it is a Bitter pill to swallow. John.
  22. The 705 is a great machine but the GMT and the GB2 are about 10x hotter and even at reduced gain settings they will see much smaller targets, but the 705 will work a bit better on larger Gold in hotter mineralization, J.
  23. You need a machine with a fast recovery, and to be able to lower the Iron volume or run it in One tone so the junk gets nulled. John.
  24. Great thread, Using a VLF/LF for prospecting puts the fun back in to Gold detecting, The fact that anyone can take part on a limited budget is one of the best traits of this hobby, It is not wise to take this hobby too seriously, spending big bucks does pile on the pressure even more so when you spend more than you should, The 70/705 are great machines and don't get the credit they deserve. keep up the good work. J.
