  1. My note was more generic in nature and not aimed at Beach Mode specifically. That said, I am not aware of any “disabling” of ground balance in the Beach Modes. I would think the regular beach hunters would have noticed such a thing and been all over it way before now. I honestly do not know as beach detecting has been the area I know least about on the Equinox. I just did a "quickie test" and it does appear changing the GB setting while in Beach Mode affects no change in ground response. I will drop a note to somebody that knows more than I do to see if I can get a comment. One of our forum members also commented on Findmall that he thinks Beach Mode is "locked" into a "0" setting. "11. Beach mode -- despite higher frequency weighting -- did not offer improved detection of high conductors, as I thought it might. One reason, I believe, may be that because ground balance is "locked" to zero in beach mode (which I did not know until today), and with my test-garden dirt balancing in the high 40s to high 50s, this was too much of an "offset" from the fixed "0" balance for beach mode to "shine" in this case (my guess)." (emphasis added). This was posted to several forums a year ago. The latest version of the Equinox Owner's Manual still mentions ground tracking as a potential option in Beach Mode on page 41. "Tracking Ground Balance can also be useful when using Beach Mode 2 underwater at the beach (in salt water)." Equinox For Beach & Water Hunting
  2. Welcome to the forum - that is some very impressive gold! 2014 USGS Report - The Mineral Industry of Saudi Arabia "Gold.—In 2014, MGBM operated five gold mines in Saudi Arabia and mined 3.86 Mt of gold ore compared with 3.28 Mt in 2013; it produced 4,789 kg of gold in 2014, which was a 15.2% increase compared with the 4,158 kg of gold produced in 2013. Most of the increase was attributed to the entry of the As Suq Mine into production in March. Production by MGMB included about 1,506 kg from the Al Amar Mine, 1,685 kg from the Bulgah Mine, 1,066 kg from the Mahd Adh-Dahab gold mine, 449 kg from the As Suq Mine, and 84 kg from the Sukhaybarat Mine. The Al Hajar gold mine in Asir Province, which produced about 25 kg of gold in 2013, was mined out and closed and MGBM was exploring for copper and zinc in the mine area. MGBM was on track to increase its gold production to 15,550 kg (reported at 500,000 troy ounces) by 2017. Production increases were expected at all the company’s operating gold mines but most of the projected increase in gold production was expected to come from the Ad Duwayhi Mine, which is located in Makkah Province. The mine was expected to produce 2,177 kg in 2015, 4,354 kg in 2016, and 5,598 kg in 2017 (Saudi Arabian Mining Co., 2015a, p. 12, 69–72, 104–105; 2015b). JORC-compliant estimates of gold resources in the Central Arabian gold region of Saudi Arabia were about 272 Mt grading between 0.82 and 8.14 grams per metric ton (g/t) gold. Ma’aden’s Masarah gold project was part of the development in the Central Arabian gold region in 2014, which had a deposit containing about 22.3 Mt of resource at an average grade of 2.19 g/t at a cutoff grade of 0.8 g/t gold according to the prefeasibility study (Saudi Arabian Mining Co., 2015a, p. 104)."

  3. https://metaldetectingforum.com/showthread.php?t=50864 One problem I can anticipate is White's boards do change over time as component availability changes. The ultimate source for this sort of info is the Geotech Forums
  4. Circuit diagram for Surf PI - probably an earlier version but it might help. Another one here plus many more More schematics here.
  5. If the reset cleared things up and then it got progressively worse again, I would be exploring the ground tracking options like fixed.
  6. Seems like a lot of us make one of these sooner of later. Lots of fun because it is a small, containable project. Looks like a nice little unit!

  8. Welcome to the forum! And thanks for taking the time to register and post!!
  9. So are you saying you made that out of melted scrap? It looks manufactured.
  10. Perfect cross link - thanks! Instead of posting the same post on multiple forms this is the way to do it. Create a new thread in the most appropriate forum. Then, if you think another forum is also appropriate (it happens) just copy the first thread link and paste into a new thread as Cal has done here. That creates the cool little link back box you see above. I do this with my own posts if I feel it appropriate. If others post the same thread on multiple forums, I usually delete the duplicates and create temporary 30 day cross links. This method works better. Desert prospecting can be downright scary at times - I have already learned my lesson there!
  11. The Minelab GPX 4800 detector was released in 2010 and was discontinued in 2012. The GPX 4800 was a pulse induction (PI) metal detector aimed primarily at the gold prospecting market but which also became popular also with relic hunters. "Gold detecting is a fascinating and rewarding activity enjoyed by people all over the world. By getting to know your GPX Series detector you can become one of the many who find gold and valuable treasure on a regular basis. The GPX 5000 and GPX 4800 are high precision instruments incorporating Multi-Period Sensing (MPS), Dual Voltage Technology (DVT), Smart Electronic Timing Alignment (SETA), and advanced digital processing. The GPX 5000 and GPX 4800 will locate gold in all types of ground, especially highly mineralised ground conditions, with great efficiency. This manual is designed to help both the beginner and expert prospector get the best performance out of their GPX 5000 and GPX 4800." Source: Owner's Manual Minelab GPX 4800 metal detector MPS, DVT & SETA technology delivers to you the most technologically advanced detector yet making small hard to hear nuggets more obvious. New timings it's like having 6 detectors in 1 enabling you to find more gold in more ground conditions. In addition to five of the timings found on the previous model the GPX 4800 introduces the new coin/relic timing Coin/relic timing is the deepest ever for benign ground conditions Improved enhance timing for more depth Improved electronics for increased target sensitivity and ground balance performance Three preset search modes gives you easy switch on and go detecting. All three general, deep and hi-mineral search modes can be modified to your personal favorite settings Automatic ground balance options make it easy to adjust the detector to suit all ground conditions. e.g. (fixed, tracking, tracking speed, ground balance type, quick-trac button) Audio adjustments to maximize target signals for your personal hearing ability e.g. (threshold, tone, audio type, signal peak, target volume, volume limit, stabilizer) Iron reject adjustable to suit the iron trash level where you are detecting Motion control, adjustable to match your sweep speed and optimize target responses Tune (also known as noise cancel) automatic and manual options to minimize electrical interference Rx gain adjustment for adjusting sensitivity Backlight so that you can read the LCD menu in any light, allowing you to detect day or night. the back light also has an adjustable timeout to help preserve battery power Lightweight Li-ion battery with inbuilt speaker booster capability One coil as standard: 11” double-D coil Languages: English, Spanish, Russian & Arabic (manual only) Minelab GPX 4800 Owner's Manual Minelab GPX 4800 | 5000 Color Brochure GPX 4000 - 5000 Timing Charts Forum Threads Tagged "minelab gpx" Minelab Metal Detector Forum

  13. I enjoy the DetectorComparison videos, he does a good job. Some not new but solid tips at the end of the video.
  14. You don't need to email or anything, just download the pdf and print. The whole "I will mail you something" thing was a year ago. I have edited Scott's original post to reflect this.
  15. Good for him, congratulations! Anyone know who won the December Find of the Month? Link? Edit. Found the link but they skipped December? Interesting the Find of the Month is administered out of the Dubai office?
  16. As has been noted elsewhere one might expect some new GPZ 19 coils to be getting sold as used soon as people get this deal and then some of them may sell the big coil to help lower their "all in" price.
  17. Adrian Harris Published on Feb 17, 2019 - On our 4th dig at K C Rallys up comes a William 3rd silver hoard 51 in total well done Garry next step reporting the find to the Worcester FLO.
  18. Several U.S. dealers are advertising a free GPZ 19 coil with GPZ 7000 purchases though 4/15. I have not been able to find this on the Minelab website so maybe U.S. only? So there is the forum "mission". Is this promotion good in Australia and the U.K. etc. or just something out of Minelab USA?
  19. That is weird. My first thought since you say it is hardened is that it is some sore of shear pin beaten beyond recognition but I really have no clue.
  20. There is nothing wrong with the X-Terra Prospect Mode. In Oz it is just more of a VLF versus the PI/GPZ side of things. I ran a Gold Bug 2 and Gold Bug Pro on hot ironstone ground in Oz with no real issue. I can get them to do the job but you may only be talking 1/3 or 1/4 the depth you might expect in low mineral ground. Personally I would not want to hunt down under with less than a good PI. But if a VLF was all I had I could go find lots of little gold with it. The PI guys leave that all over the place though the SDC is amazing and is getting a lot of that now. But who wants to go to Australia to hunt tiny bits?
