  1. Julie, The 800 is a truly light and versatile machine. I've used it in all the areas of Southern California that you have mentioned. I've found some small gold with it using the standard coil and I've found many gold and silver pieces of jewelry on the beaches. It works! What have your results been with the Garrett Ace 250?

    Tips For Buying A Minelab GPZ 7000 ?

    I would say you have some ideas there and I hope your hopes come true. It should not be for any of us to say it can't be done. There is still lots of gold out there. What I would say is that there is a 'difference' in exploring old mines and tailing piles and prospecting them. Research the present owner to know if you are on a claimed location. You want to go back again and again to that gold you do find so have someone help you file a claim. If there are going to be two of you prospecting you should consider a second detector in a VLF category. As a matter of fact you may want to get the second detector first when considering the areas you are working. You may not need the Zed power to find that gold. Wait for other replies and for the snow to melt and then you should be ready. Mitchel
  3. The primary reason I bought an Equinox 800 was because it was going to let me discriminate better than any detector I had or knew I could buy. It would save me from digging many, many bad targets. That is what I focused on. Second I believed that it might 'see' some targets that have been missed. When it came out with the standard coil I think it lived up to its billing. I've found gold and silver at the beach and gold nuggets in the gold fields. The discrimination has helped also with the 6" coil in can slaw to find good vs iron targets. When it comes to the 15 inch coil at the beach I'm beginning to wonder. While using Beach 1 and Beach 2 in wet sand I feel like I have to dig everything to get all of the clues I need. I still find myself comparing this coil and detector combo against the 3030 and the Explorer SE Pro. (I dug most everything with them also.) The clues I seek are not just the type of metal but size also. Tonight's hunt was an example. I went to a beach I know pretty well and found it to be without a cut and gently sloping. The waves have been at 14-17 second intervals so I expected targets to be deep if I could find them at all. The tides are staggered so that one of the lows is very high compared to the other. (It is this high low tide where I found most of my targets tonight.) There is not much current and there is not much wind. Big things didn't seem to be moving as I didn't see many rocks. But, we have to hunt what we get on any particular session so away I went. My set was Beach 1/21/5-6/5 tones/no discrimination and everything else pretty standard. Going out I swung fast looking for good targets and clues. I had to see where the energy in the water had buried my targets. There were very few in the normal places but I did find the earring at the top left after a few pennies and one nickel. I went on to try areas where I have found hundreds of coins and many rings but nothing tonight. It was a nice night when I returned to the area where I had found the two pieces of small jewelry. I was no longer 'driven' as I am many times so I took a more thorough, casual approach and made sure I dug everything. This was when I found most of the objects in the pictures. Everything was still on all metal but I was digging the bobby pin sounds, the -4, -5s and the 2s and 3s. (The leaf earring at the top left was a 2!) I was saying to myself 'Do you know what you are not digging?' I thought I did but I was also surprised several times. On a 'good' night I might have skipped digging many of the penny sounds but I dug them and found good clues. One negative sound was the stud in the bottom right. It was a negative number but it is a small object for the big coil. Many of the targets were small. As you can see the 'bump-bump groan' sound produced a fair amount of trash also. There were wires, hooks, bobby pins and a toe ring and a rose piece of small jewelry. There is also one of those iron Euro 1 cent pieces. Tonight they were all interesting. After all of these little objects were found in most of a 100 yard stretch out of 2 miles of walking I came across another negative number. It didn't sound any different than the other nearby targets but then I hit something with the scoop. It was large and out popped the piece of threaded pipe. I would have expected to have my 'doors' blown off but it was not any louder than the bobby pins. I know it can be set differently on the volume and I should do that. The Beach 1 low numbers have a certain volume. Now it seems that determines the headphone volume more than the adjustable volume on the detector. Anyway, I was quite surprised that it was not louder. To wrap all of this up and get to the point of the topic, it seems that the 800 with the 15 inch coil detects small objects well. The depth was up to 8 inches. Some of the deep sounds don't ID well so I don't rely upon the discrimination. There is a range of good targets that could be 'missed' if you only dig by the numbers. It is important to know what you are not digging and only skip a target when there are other better targets near. Even tho the 800 is a fast detector, the 15 inch coil likes to be swung slow. Mitchel
  4. Thanks for your thoughtful post. Getting gold with the 6" Nox is an accomplishment I've yet to achieve. I've gotten many, many pesky shotgun pellets. I'm saddened by the passing of Mrs. JW's mom and touched by the picture you made in the church. My parents were married at a similar point in time in the middle of the last century. In too many ways those thoughts and pictures are from an era that is quickly slipping away. I was not part of the era but heard about it in my formative years but I can't pass it on in the way my parents lived it. Mitchel

    Discriminator Or Detector?

    I have been out every night on pretty much the same beaches because I want to learn about this wave pattern. The pattern is not the point of my posting here so I'm going to make a point about a couple of things I've found. A couple of nights ago I got a solid 10 and that usually indicates something different. As it turns out it was. It is a stainless steel man's ring. I've found gold rings at 10 also. Of course I'm going to dig it just like I do the 13s which are just about always nickels. Fringe detection on the 800 is probably what I had been referring to when I spoke of 'lack of discrimination' in my first post. When I get a deep detection on the 11 or the 15 often times it doesn't have a good ID. I've found that multiple targets can be unidentified at depth but also chains and other jewelry. Corroded pennies can be from 12 to 22 in my most recent experience. I'm not swinging anything else right now so when it doubt, dig it out. Mitchel

    Discriminator Or Detector?

    Tonight I went back out to the beach one more time with the 11 inch and results were dismal because I've hit it and not much has changed. I went to the SAME beach to understand that beach. I've never done that 3 days in a row. While working it tonight I remembered when I used my new 5000 on the beach back in 2011 and 2012. Now that is a pure detector but I was staying out of the water. (I'm thinking about using it again with the beach program and a Coiltek that I have.) I know a couple of guys that use beach PIs. I think they find a lot more than I do but they have to dig a lot but ... am I trading off too much to use a CTX or Equinox? What more would I find if I used a beach PI? What would I not find if I used a beach PI? Let's just limit this to Beach only and specifically tide beaches that have been under water at high tide. The way I think is a PI is pure detector. (I know you can hear shapes but it basically detects metals and you dig them.) The CTX, Explorer and Equinox is a detector with discrimination. The Equinox is very fast and can distinguish (discriminate if you will) between different types of metal nearby or sometimes within the same target (a sandwich coin). I need to understand the standard sounds and screens or program the detector better to get the most out of it. Clive's books are going to help. Mitchel

    Discriminator Or Detector?

    Let's do a little bit of thread combining here. Over on the main forum it was said on Page 3: Trashy mining sites hiding good gold have been waiting for a new effective multi frequency detector that excels at discrimination...... Hello NOX 800
  11. Yes, JW, I agree. But look at all the clues that were left behind from the era before metal detectors! My point was that we should and do seek out gold spots found WITHOUT a metal detector and we then try it WITH the 'easy find' tool as you describe. Mitchel

    Discriminator Or Detector?

    The little rings are nice but they are not silver or gold. I got a couple of silver rings earlier in the week but they are not pictured.

    Discriminator Or Detector?

    Tonight I went back to the same beach. When I got there someone was detecting 'my area' so I leap frogged the detectorist and then worked my way back. Sure enough they came my way and I went back to my area to see what was left. (I wasn't overly concerned because they walked very fast and had a hand scoop!) The setup was exactly the same except I put on the 11 inch coil. I found I could run it at the same sensitivity (21) but I also bumped it up to 23 near the end of the session. Swinging the 11 is a delight after many sessions with the 15. The beach was similar to last night even tho some big waves were coming in at 15-17 second intervals. The hunt was about the same length of time and when I got back to the area I found an earring (the brass looking one). I slowed down and began finding hooks and bobby pins like the previous night and in the same level of sand. I was able to see it with the 11 and some targets were 10 inches. The little rings (3) were not negative but low tone. The most interesting thing was to find the matching earring from the previous hunt. When I got up this morning and looked at the cleaned first piece I noticed it still had the holder. I thought the second or matching earring would be around some place and I found it. Both coils work on the beach but the 11 is a bit clearer. Mitchel

    Discriminator Or Detector?

    Chase, When I say discrimination I mean accurate ID of a target. This would mean that gold would not be masked or confused with iron stones. It would mean that you could 'see' through can slaw that others could not. With the new and improved multi-frequency it would be hard to fool this detector. What I think I have now is a very good detector that needs quite a lot of interpretation to get everything out of it. (I just opened my package from Clive with the Advanced Guide in it.) For the last couple of months I have not used any other detector. As they say, results may vary. Mitchel
  15. Thanks GB_Amateur I have a specimen that is considered to have 8ozt of gold. When you shoot it with an RF gun the gold is somewhat less than pure. I've seen ranges from 85 to 95% so just as there is no pure quartz there is no pure gold in the field. Field testing and sampling requires an assay and then you find out what was in a rock/specimen after the fact. Then you could say you wish you had kept it in the original form. The large nuggets/specimens just found in Australia will have many ounces of 'impurities' in them that could affect their value but probably not much because they are unique and collector's items now. Mitchel
  16. You lads over there would have the advantage on us as to nuggets found with a detector and specific gravity calculations I suspect. Your dolly results are the proof that we sometimes never see. Hard rock gold is often times not tested before crushing and that is not found with a detector.
  17. Common Variables (Enter these values first and then proceed to either Method 1 or Method 2 below) Variable Value Specific gravity of the gold or the first mineral (Sg) Specific gravity of the second mineral (So) Dry Weight of the sample (Wsa) Significant decimal digits in answer, default 1 The number of significant decimal digits should be set to the least number of digits after the decimal point in the input values. For instance, the value of 18.6 has only 1 number after the decimal point. Thus the number of significant decimal digits should be set to one. Calculations are set to use one more digit than this entry. The Common Variables above must be completed before proceeding. For either method below, fill in the first value and then press the Calculate button. The bottom 2 values are then computed. Method 1 Variable Value Weight of the displaced water (Ww) Calculate the weights of both minerals Weight of the gold or the first mineral (Wg) Weight of the second mineral (W2) Method 2 Variable Value Weight of the sample in water (Wsw) Calculate the weights of both minerals Weight of the gold or the first mineral (Wg) Weight of the second mineral (W2) Method 2 242 g for dry weight 173 g for wet weight 69.9 g Gold I like this calculator because you only need two values and you don't do any math. That has all been done. My copy and past of the formula from the link does not allow for calculating but you can plug in the numbers. The way you 'play' with the formula is to determine a closer density for the host quartz. All of these assumptions are covered in the link. Mitchel
  18. There has been way more gold found without a detector than with one! Mitchel
  19. I always use this calculator. http://desert-gold-diggers.org/gold/specgrav.htm Recently I came up with a negative weight on a specimen like you are doing with this one. I had to re-weigh the specimen more accurately making sure the wet weight was not touching any sides of a container with the water. As has already been stated, your specimen should weigh more in water than what you are reporting to us. Something is wrong if this is a host of quartz. We still haven't seen a photo of the specimen so no further help can be given. Mitchel

    Equinox Up Date

    I was 'hoping' there would be another update ... but I don't know why. Perhaps just for the new coils? I'm ok with things as they are and can't remember what it is like without the update. Mitchel

    Last Gold Of 2018

    Just another half day for ya. More than I get in several months. Well done. Mitchel
  22. Here is an article that argues that peak gold has been seen from mining. https://www.coinworld.com/news/precious-metals/2018/07/world-moving-toward-no-gold-mining-options.html When you look at the coinworld pages you will see lots of other interesting gold articles if you like to read such things.

  23. It has been a few weeks since I went out on a gold trip. Today was the day and the weather was ideal. I went to a location I've been to many times before and people are still getting little pickers out of the area, but not me! My tool of choice was the 6" Equinox set on Gold 1 or Gold 2. It was set up for the hunt. I'm always amazed by the size of stuff this combination will find. None of it was very deep. I know GB2s, Monsters, 7000s, 2300s and others have been over these slopes but there is still trash. There are pellets, half pellets, split, shavings, etc, etc. Do you see any gold there? (The dime was found with my eyes at a parking area!) I don't either. I tried 3 different places with a combination of open and raked slopes and tailing piles. Nada, so it was time to do something else after 5 hours. On the way back to Los Angeles there was an old train stop. We've been there before and gotten coins. The coins I got were buffalo nickels and wheat pennies. The last 3 times I stopped there I didn't find any but I had more time today. Let me see. I put the 6" coin into Park 1 and Park 2 and began the search. I've been here with the 6" coil before. I'd also been there with the 3030 6" coil. I think I have 10 coins from the area. I went back over the areas where I had found the most and about 20 minutes into the search I got a coin signal among all the can slaw. Out pops the wheat. It's a 1945, I can read that even without my glasses. Now I expand my search area a bit but still on the little slop that has held the coins in greatest quantity. I have enough confidence in this coil/detector combo now to not use all metal. That is just too noisy in some places like this. I'm about 20 on sensitivity and everything else is factory on Park 2. I'm hearing another penny sound so I scrape away at the surface and the signal is still there so I take the little hand pick and loosen the area and pull it out of the hole. It's only about 4 inches deep but I get the target. I see the shape is a coin ... the numbers aren't a dime but I think maybe ... then I look and I can't see the wheat ... wait ... I've gotten these from coin hunt tokens ... IT'S AN INDIAN! This is my first Indian from the field. It is a 1905. It's not in very good shape but I think I'll keep it. The 6" coil didn't get me any gold but did get an old Indian. What a detector.

    Black Sand Beach Detecting

    So, I go out tonight to a familiar beach just a few miles from the troublesome beaches of last night and the 15" coil just lays down in Beach 1! I could run the sensitivity up to 23 in some places but it worked just fine without a weewaww at 22 everywhere. The waves had been very small so light targets were plentiful but a few deeper quarters and 2 hours later I had a couple of bucks and I wasn't fighting the settings. Better targets to come. Mitchel

    Black Sand Beach Detecting

    I just got off a black sand layered beach brought about because of some wind waves. There were not many good targets and it was a struggle for 4 hours. I had to experiment with different settings and modes more than normal. Slowing down does help. I was using the big coil and the ID is much better when going slow. The problem with slow for me is that I can't find the patches. I slow down and grid when I find a patch or I circle a find to see if there are other targets near. When swinging fast in Beach 1, tracking on it was still picking up the sand. I changed the speed and some areas needed to be fast at 6-7 and others slow at 4-5. The sensitivity I kept above 20 if possible but some places had to be down to 18. Most of the targets were down 8-12 inches. (I was not the first one on parts of this beach and someone had left open holes from a sharp sided digger. The holes could break an ankle if stepped in.) I also experimented with the tones. Sometimes 5 tones is better than 50. Two tones can be interesting to distinguish black sand from target also. When I was swinging fast I noticed that the first couple of passes on deep targets was always negative numbers. In my mind I'm saying this is a 'dig everything' combination of the big coil and iron beach. I think the Nox is much more stable and ID friendly with the 11 inch coil. The problem is the depth of targets. When I got the negative numbers I purposefully would dig 6 inches off the top and then target IDs would then become important again. Pennies, nickels, some dimes and even quarters came from the first set of negative numbers if it was really deep. I was walking in wet sand with the tide waves coming in and also on damp sand. It didn't seem to make any difference. When in the damp sand on the steep slope of the beach I experimented with modes. Beach 2 was more quiet and stable. On a couple of targets I ran through all the modes and Field 1 turned out to be as good as both of the Beach modes! I dug one cell phone at 20 inches and one is still in the hole because it beat me. I found one shallow silver earring and about a $1 in change which is very poor. Better conditions ahead ... Mitchel
