Underwater With The Equinox 800

Recommended Posts


Great report. It sounds like detecting in Hawaii - the hot rocks there give VLF detectors fits and are good at hiding targets that only a PI can reveal. Obviously finds can be made but it can be a noisy go deciding what signals are good and which are not. Much as I like the Equinox for water hunting it will not replace a PI for the worst stuff.

Personally I would recommend a higher recovery speed in hot rocks. Your problem is not absolute depth but relative depth, and a higher recovery speed will reduce noise and let the machine see targets between and next to hot rocks better.

Id say you found more than a few pieces of gold.   

The Nox, much like the CTX, prefers speakers like the audiosears over the piezos.   But those speakers arent cheap so not many use them they arent as easy to seal either for water hunting.   Not many phones perform well underwater for a lot of reasons either.   To me .... its more about finding a pair of phones that are properly sealed for constant dunking.   Its bites ...... but the cheap ML yellows do do that..... but dang i hate those things.   We may see MAL or GGA soon ..... but i think there wont be a big change in sound.

While I like the Hungarian yellows, I need something with more sound blocking. I don't dive and these have no sound blocking at all.  In fact, they seem to amplify the noise from boats, jet skis and even the wind.  I bought one of the adapters a while back and am seriously considering converting the Koss QZ-99's over.

They are easy enough to pop apart, just pull the squishy part and the rest pops out with it or use a flat head to get in there.

You could probably stuff some foam in there or other material for sound blocking.

Had another cracker day yesterday and my first SCUBA with the equinox, had so much fun too! 😊

here is yesterday’s top treasures:

I’m thinking about attempting some alternatives for water use, I’ll post them if they ever come into existence

Don't use foam to insulate (unless closed cell) if you are using them underwater, you won't like the smell after a period of time. Applying silicon to the  inside of the ear cups will help and not stay wet when out of the water. Taping over the vent and drain holes helps some too, just remove the tape IF using them underwater.

I just tried pulling them apart and it isn't happening  I'm not going to attempt further risking damage.

So the Koss phones are getting modified and if they work out I'll sell the Yellows.

      I dont want to stay indoor and i got the green light to go detecting.
       
      Any infos will be welcome.
       
      Thanks

      I am an avid metal detector user and I like always being at it. Just because there is no gold prospecting for me in a given time frame is no reason to not go metal detecting for gold. There are a lot more ways to find gold than prospecting, and so jewelry detecting is very high on my list. If you like finding a gold nugget, I do not see how you could not also be excited about digging up a gold ring.

      Jewelry detecting and nugget detecting share many common traits, not least being the hunt for gold. Both also require a high tolerance for digging trash items, and both are best done with detectors made for the purpose. It just so happens that the detectors best used for nugget detecting are often the best to use for jewelry detecting.

      In other words, a lot of you guys are already outfitted for this!

      There are two general ways to hunt for jewelry - on dry land, or in and around water. Let's leave the dry land for another article and focus on the water detecting for now, since I am gearing up for a water hunt myself right now.

      Almost any detector, with the remarkable exception of the most expensive one you can buy, comes with waterproof coils and can be submerged to the control box. Minelab PI stock coils are not warranted waterproof but only water resistant so it takes aftermarket coils to get them up to speed. But they are a poor choice for wading as there is probably no machine I would like dropping in the water less than a GPX 5000 with high amp battery attached.

      Detectors that can be hip or chest mounted offer even more flexibility for wading applications. Few nugget detectors are fully submersible, but there are a few, most notably the Garrett AT Gold, Infinium and ATX, all waterproof models.

      Water detecting can be broken down into fresh water and salt water detecting. Fresh water detecting is pretty straight forward since fresh water is invisible to your detector. The tuning and operation of the detector is similar to what you do on dry land. All you have to worry about is keeping the electronics dry, and recovering targets underwater. Fresh water swimming holes are great for jewelry detecting, and there are many fresh water stream and river opportunities for gold prospectors. Any good gold prospecting detector also works well for freshwater beach hunting. The Garrett AT Gold has an obvious edge for being waterproof. The Tesoro Lobo gets special mention for being convertible to hip or chest mount.

      In fresh water VLF detectors usually have an edge due to large amounts of trash often being present but PI detectors do have their place in fresh water detecting. The only way to know is to just give it a go and see how much trash there is. The nice thing about beaches though is the digging is easy compared to what nugget hunters often face.

      Salt water adds a whole new dimension. Salt water is conductive, and therefore a hot metal detector can actually get a signal from salt water or wet salt sand. Many prospectors already know the issues surrounding salt and alkali flats. Detectors that are used in salt water need some way to tune out the salt signal. The problem is even worse on beaches that have mineral content, classic black sand beaches. A white beach composed of broken down coral and shells is no problem at all, but add volcanic material and the issues compound. Most prospectors would not be surprised to hear that pulse induction (PI) detectors have an edge in dealing with salt water scenarios.

      There is an unsolvable conundrum however. The signal for salt water and small gold items, like post earrings or thin gold chains, actually overlaps. When you tune out the salt water, you tune out these items also. There is no solution to this problem with existing metal detectors because of the way they work. It is possible to find these items at the beach using a hot detector, like a White’s Goldmaster or Fisher Gold Bug 2, but you must be on bone dry sand. Any attempt to get near wet salt sand with these units will result in the sand acting like one giant target.

      Most mid-frequency gold machines handle salt water beaches to varying degrees. They will generally have no problem until you get on sand currently seeing wave action or actually in the water. The higher the frequency, the less able to handle wet salt sand. The Fisher Gold Bug Pro at 19 kHz and Garrett AT Gold at 18 kHz are not happy on wet salt sand. They can be made to function but only by losing a lot of depth. The Tesoro Lobo has an alkali setting and White’s MXT a salt setting specifically designed to handle wet salt sand. In general though these detectors will all work better higher on the beach and have an edge on small rings, earrings, and chains that other beach hunting machines tend to miss.

      The Minelab Eureka Gold and X-Terra 705 have low frequency options that make them well suited for beach hunting. The Eureka can be hip or chest mounted, but be aware the stock coil is another that Minelab does not warranty as waterproof.

      The PI detectors fare better, the Garrett Infinium and new ATX having an edge again for being waterproof designs. The White’s TDI and Minelab series do well but must be kept dry. The TDI models except the TDI SL have an advantage in being convertible to hip or chest mount. Be aware that turning off or not using a ground balance system can often add extra depth with a PI on white sand beaches. The TDI and GPX 5000 can turn off the ground balance setting, and the factory default on the ATX before ground balancing offer possibilities on low mineral beaches.

      For serious salt water beach detecting hunters turn to detectors not normally used for prospecting. Ironically, this is because the general lack of sensitivity that makes prospectors eschew these models makes them ideal for salt water. Multi-frequency VLF detectors are not very good prospecting machines but they excel in salt water. Two detectors that vie neck and neck in the salt water VLF market are the Fisher CZ-21 and Minelab Excalibur. On the PI side the Garrett Sea Hunter, Tesoro Sand Shark and White’s Surf PI are the three popular models.
       
      Minelab Excalibur II waterproof metal detector
      There are lots of options but if you ever want a specialized waterproof detector for both fresh and salt water and want to make a safe choice, get a Minelab Excalibur. It is probably the most popular water detector made and for good reason. It gets the job done with minimum fuss and will work well anywhere.

      I am a PI guy myself however. I have used the Garrett Infinium extensively trying to deal with salt water and volcanic sand and hot rock conditions in Hawaii. I have had success with the model but it is difficult to deal with, suffering from an inability to ground balance into the salt range and susceptibility to EMI interference. Huge numbers of posts exist on how to try and get an Infinium to behave in salt water. The new ATX has taken steps to address these issues but the jury is out there yet. I will be giving the ATX a good go in Hawaii soon. My latest water detector is a White's Surf PI Dual Field to back up the ATX. I have had good luck in the past with the White's Surf PI models and recommend them for people interested in a waterproof beach PI. Again, a simple unit that gets the job done, and at a bargain price.

      Where to hunt can fill a book, but really boils down to two things. The first is that the best finds will be made where people who wear quality jewelry congregate and engage in some kind of physical activity. On fresh water beaches where items get dropped is generally where they stay. The second item comes into play more often on salt water beaches. The waves and seasons concentrate items on layers, much like placer deposits. They sometimes bury the items too deep to find, and at other times expose them for easy recovery.

      Beach watching can teach you a lot. There is the towel line, where people set up shop for the day. Lots of items get lost here. Then there are the places where people tend to play beach sports, like Frisbee or volleyball. Best of all, are areas in the water where people congregate, with areas where people can actually stand on the bottom being best.

      Items dropped in sand obviously sink over time, but hard sand will resist this longest and keep the targets close to the surface longer. Extremely soft sand swallows items quickly and is not a good place to hunt. Areas where the sand tapers into a hard rock or coral bottom can be very good when the overlying sand is shallow enough to reach that hard layer with a detector.

      Beach detecting is very popular, but beach hunters have on tremendous advantage over prospectors. The finds are being constantly replenished. There is no beach, no matter how heavily hunted, that does not have the potential for finds. The more activity there is the more items are lost in a given period of time. The finds made by beach hunters can rival the best made by prospectors, as not many gold nuggets come with diamonds attached.

      I know for many prospectors it is about getting out into the middle of nowhere and away from the crowds. Beach hunting is not for everyone. But you can hunt early in the morning or even on rainy days, when people are few and far between. As more and more areas accessible to prospectors get hunted out, it is possible other places are near to you where gold may be easier to find. If you have a detector already you certainly have nothing to lose by giving it a go. Hopefully this post has at least made you consider the possibility. As always, volumes more information can be found just by Googling “beach detecting forum”.

      Here is an example of a hunt at White's Surf PI Pro and Platinum Rings in Hawaii I got four platinum and three gold rings over a couple week period. One of the gold rings is white gold so it looks like only two gold. All fairly plain men's bands reflecting the rough surf area I was hunting. There is a picture of everything I dug at the link including the junk. All the platinum I have ever found was rings, and when platinum peaked at over $2000 an ounce I cashed in over two ounces of platinum.

      Another very successful hunt was Detecting Gold in Hawaii with the Garrett Infinium Please note that unlike my prospecting outings I do not spend every hour of every day in Hawaii detecting. These finds are being made hunting on an average of two or three hours a day. I am not one to just sit around so detecting keeps me busy. And a good vacation can be paid for in finds or at least subsidized with some hard work and a little bit of luck.

      Had a day to hit my favorite gold beach, so I took advantage of the day. What looked like some sand had been removed in reality didn't pan out. Still fairly sanded in, and after digging some pull tabs at 10-12 inches, I figured it was going to be a strictly exercise kind of day. Not many coins on this small beach so I was just going to enjoy the day. Got another deep signal that I thought was going to be a crusty zinc penny and after digging 12" I final got it out. Now to use the pin pointer to get my crusty junk money, but instead what appears is a fairly good size man's gold ring. To say I was shocked is an under statement . Made my day and the Equinox was hitting nickels hard, most at 10". Two war nickels, 1935 Buffalo and some earlier Jefferson's ('39, 47 etc.) I mostly use Beach 1, manual ground balance (there is some black sand mixed in) and as high a sensitivity as I can handle.  The only drawback is I can not get myself to stop digging them small targets. I always think I may miss small gold studs, or thin earrings. When you keep digging the extremely small disc that holds the two pieces of a pull tab together, you think you would learn a lesson, but not me.  Even on a fairly sanded in beach the Equinox always seems to give me something good.

      Didn't find much. A few dollars, a junk ring, wine bottle opener and, what I think, a nose ring. I was surprised to find such a small thin item with the 15" coil. Or should I not be surprised that the big coil found the nose ring even though it is so small? Big coil, small coil no difference in hitting the small items? It was certainly hard to pin point. Here is a pic with a dime for comparison. The nose ring has tested as silver.
