  1. Ganes Creek, Alaska was mined with floating bucket line dredges and more recently dragline and bulldozer mining. The tailings in that photo are dragline poles that have been flattened out. See my Ganes Creek stories for lots of photos of both types of tailing piles.
  2. Weight is 730 grams or 1.069 lbs. it’s an almost exact copy of the Deus rod so no way it could weigh 3 lbs.
  3. Awesome find! I have wanted to visit the diamond park for years. The odds of finding a diamond are halfway decent. I almost gave it a go on my last drive to Florida but got stuck in a tornado storm front right about the time I was passing through and decided to keep going. Maybe next year.

  4. Welcome to the forum! Rest assured a properly tuned metal detector will “handle” any ground. It simply requires reducing the sensitivity until the detector is stable, and then working within whatever limits that imposes. Gold can be found with most any detector if on good ground and with a skillful operator behind the machine. I am not saying all detectors are equal, but the truth is it’s the operators that vary far more than the detectors themselves. Enjoy!
  5. You are a good man Skate, thanks for posting your story!
  6. They were putting a sticker on the end of the box with the version number after the change was made but I am not sure if they are doing that with the latest units coming off the production line or not. Does not really matter I guess, just check and upgrade if needed. Equinox - How To Check Version Or Rollback To Older Version
  7. Quite a bit was made of ferrous falsing with the 6" coil a year ago after the upgrade, but nothing much seemed to come of it. I did some limited testing with two Equinox 800 both set up with 6" coils on tiny gold nuggets in bad soil. Short story is I could discern no real difference. There appears to be little downside to going to 1.7.5 from my use so far and with 1.5.0 having the known issue with silver on edge I am going all in with 1.7.5 and not looking back. Thanks for the feedback folks. Equinox - How To Check Version Or Rollback To Older Version Thread asking same question a year ago
  8. Dilek is without a doubt one of the most humble and honest persons that I have ever met in my decades in the industry. She does not hype the product but lets it speak for itself, and never badmouths the competition. I have never met her but consider her a friend, and wish her good health and success wherever her path leads her.
  9. The last “semi-official word” was posted on June 26 here: “the silence is goldenlol, it's a French expression, but I do not know, if it is well translated ...in short, some newsAQ production must "normally" start on July / Augustthere was some change on the machinenew stickera setting mode addand performance in reject modesignificantly improved (result of the first research on Terra)” I think it is safe to say that earlier they were thinking they were close with production expected in July/August. Then an unexpected delay occurred, and there has now been an information clamp down. That does not tell me the machine is imminent, just the opposite. It may get released tomorrow but I for one am not holding my breath. I personally now just figure next year, and that way if it comes earlier it will be a pleasant surprise.
  10. It depends on the ground conditions and the target. In air tests I would expect the large coil to do better on coin size targets, and on very small objects I would expect the small coil to do better. For neutral soil you can determine the difference yourself with simple air tests. That is your baseline. As ground mineralization increases the difference between a small coil and large coil changes. Large coils “see” more ground and as the mineralization increases the large coils are more impacted by the mineralization. I have seen ground where large coils have to have the sensitivity reduced so much that I was better off with the small coil even on coin size targets. For tiny targets a small coil is almost always superior. Target/trash density also matters due to target masking, with small coils getting more “apparent depth” by being able to detect shallow targets a large coil misses entirely.
  11. Simon, I dare say you found something rarer than any coin these days... a place that for some reason has never been detected for coins! That is quite literally what it used to be like in “the good old days” when any park or sports field gave up handfuls of good coins in short order! Good on you, great finds!!
  12. Some people believe the pre-DST models are hotter. The main issue is that in some urban areas pre-DST units are unusable. You can supposedly disable DST but on the unit I had it seemed to make no difference - the unit stayed the same DST on or off. There is a lot to like about the T2/F75 platform. Not least being that on my arm at least it's the best feeling detector I have ever swung. There are lighter units like the Deus but their nose-heavy nature offsets the lack of weight. The T2/F75 perfect balance has less wrist torque and less arm strain in the long run even though it weighs more. It's near impossible to get proper balance in a detector that weighs less than 3.5 lbs as you have to have the underarm counterweight. You will never see specs like this in any other detector manual: Weight: 3.5 pounds (1.6 kg) with alkaline batteries installed. Static Balance: force in vertical plane normal to elbow 0.47 pounds (0.22 kg). Varies with adjustment and user’s stance and arm/hand physiology. Dynamic Balance: axial moment, 0.29 foot-pounds (0.39 newton-meters). Varies with adjustment and user’s stance and arm/hand physiology. Sweep Effort: lateral moment 5.2 foot-pounds (7.1 newton-meters).
  13. The T2+ was not a new model and as such was deceptive from a marketing standpoint in my opinion. It and the F75+ are the same as the prior Ltd models... the only change is the accessories offered with the units. By changing the name they strongly implied without directly saying so that the “plus” models are new models with “plus” functionality somewhere when in fact all they have is a decal change. Relabeling taken to the extreme. It left a very bad taste in my mouth regarding First Texas marketing practices, from a company that plays high and mighty as regards other companies marketing practices.
  14. The 600 is a great unit and for many the best value by far. I very often just use the presets with a small tweak to sensitivity and therefore am probably going to get a 600 for use as my dedicated saltwater unit plus general backup machine.
  15. Most detectors have simplified control sets that combine several controls into one or leave other controls out entirely. The White’s V3i offers more granular control of the detector at every level possible and so it’s manuals are a lesson in how detectors work. One main reason I own a V3i is because we will never see another detector again with this level of control. From the White’s V3i Advanced User Manual: Sensitivity Once you select a basic program you may need to adjust the sensitivity settings. Most of the V3i programs are set up with nominal sensitivities, but some (notably the ‘Pro’ programs) are set up a little hotter. Most users believe sensitivity should be run as high as possible. In some cases this is true, but if you find the detector is noisy and falses a lot you probably need to turn it down. There are three primary sensitivity settings, plus a boost mode. Rx Gain Rx Gain (sometimes called preamp gain) sets the gain of the receiver’s input amplifier. In most cases, you want to set this as high as possible and still maintain stable operation. Three things can limit the maximum gain setting. The first is external noise, such as electro-magnetic interference (EMI) including 50/ 60Hz mains and RF. EMI typically shows up as erratic operation and noisy audio. Secondly, in highly mineralized ground excessive gain can cause the input amplifier to overload or operate at close to overload due to the large ground signal, limiting the available range for target detection. Finally, the quality of the loop null can also push the input amplifier toward overload. White’s V-compatible loops are designed to minimize null limitations, but third-party loops typically have wide variances in the quality of the null which can require a lower Rx Gain. EMI affects the lower end of the signal range, which more directly impacts target sensitivity. Both ground signal and loop null affect the upper end of the signal response range, which usually results in a quicker overload. Ground signal and loop null affect target sensitivity only so far as the Rx Gain must be reduced to prevent overload. All-Metal Sensitivity All-Metal Sensitivity (sometimes called DC sensitivity) determines the responsiveness of the all-metal channel. Only target signals above the threshold cause an all-metal response, and a higher all-metal sensitivity setting will increase the all-metal audio response rate to targets. This setting affects all-metal modes including pinpoint and mixed-mode, but does not affect normal discrimination mode. Setting this too high will make the all-metal audio chatter. Discrimination Sensitivity Discrimination Sensitivity (sometimes called AC sensitivity) determines the responsiveness of the discrimination channel. This is a threshold level, so only target signals above the threshold cause a discrimination response. Setting this too high will cause noise and falsing in the discrimination audio. Tx Boost Tx Boost is transmit boost. When enabled, it triples the transmit voltage applied to the loop (from 10V to 30V) and increases the depth. Using this feature has two major drawbacks: it can overload some loops (reduce the Rx Gain), and it quickly drains the battery. There are two common uses for Tx Boost. One is when hunting an unusually “clean” area where most targets have been cleaned out, and only deep targets remain. TX Boost typically gives about a 1” depth increase. The other is when EMI noise is severe. Reducing the Rx Gain reduces EMI but also reduces target signal strength. Applying Tx Boost increases target signal strength but does not increase EMI noise, so Tx Boost can be used to improve signal-to-noise.
