What Keeps Gold From Falling Too Deep To Recover On Beaches?


Recommended Posts

Hey folks! I got into recreational prospecting a few years back and love it. One day YouTube decided to show me some metal detecting videos and now I love the idea of jewelry hunting on the beach. Planning to buy a Vanquish or Simplex and get into the game on some NorCal beaches.

That leads me to a dumb question - when the ocean washes over a gold ring on the sand, given that it is so much denser than the surrounding sand why doesn't it sink so far that it's undetectable?

In the Sierras I need to get down to bedrock to find decent gold. Is there a small recovery window to get gold jewelry prior to it going so deep that it can't be recovered? Is the ocean constantly pulling off layers of sand at a rate that's somewhat similar to the rate the gold falls?

Trying to understand the basics so I can grasp where I would have the most luck on a beach in the wet areas.

Actually the principle of a firmer and harder layer is correct if You talk about where the heavy stuff quit the descent...The problem is how fastly will be covered with more sand to be still detectable. This is one of the reasons cause most of finds are usually old stuff buried long time before and uncovered by the ocean in certain days, sometimes years after.

The beach is a sort of an hell, really different from other environments and can change in hours, daily.

Supposing that you have an area on land that produced gold nuggets before, You still can find almost the same area with little differences even months after, maybe with icy ground or snow in the worst case.In the beach, after a tide cycle, anything can be different. It all depends on how far the coil is from targets and this change continuously... That's the principle of crazyness I'm victim of....

Over here it seems to be a cycle of sand build up especially in summer, sand removal in winter and hurricane season. Sand moves around obstructions like piers or seawalls. I have noticed after a day or two of heavy surf from the right direction, things get churned up and redistributed. Then if the beach has lots of people who wear and lose the type of jewelry you want to find, how long since they dropped it. And when will the other detectorists arrive? Some say the shape of jewelry has a lot to do with it's movement. I hunt the old stuff so not sure about that. Happy hunting!

Nothing stops that from happening, and most items in actively moving sand do sink farther than we can detect. They end up on hard layers, or as deep as the deepest storm scour that has occurred since they were lost.

    If you want to get a continously updated,  in-depth explanation's of beach dynamics, go to TreasureBeachesReport.Blogspot! He is very good at explaining how all different objects behave in the surf zone, and dry sand areas! And how to read the beaches!👍👍

My experience is the heavy objects only sink an inch or two,but the wet sand moves sometimes erosion maybe several feet deep releasing buried treasure (rings and coins) Those not found maybe covered up by sand when the sand is move and fills the area back up.

Steve and FloridaSon are on target.  Gold will continue to sink in the sand until some denser, compact layer or obstacle stops it.  If it doesn’t hit hard pack, it will definitely sink out of detector range.  That factor is why we watch and hope for serious erosion...especially along the treasure coast.  Once heavy tides have stripped away multiple layers of sand, previously undiscovered goodies can appear.

Here ..... Being the Chesapeake Bay anything is possible. Movement of gold can be nothing up the coves and rivers other then sinking to a harder layer...........then in the open bay gold can be on the constant move until it hits something to slow it down or stop it. Being most of the beach's were closed in the late 60's you would think all has found a resting place. But seems there is no way of predicting...you just have to get out and do the time and find the openings..and hit them hard while its good for it can change as fast as it opened.

One thing about storms, they can be great,........ ok..or devastating to a beach...

My first year of metal detecting was 2008, we had the perfect storm come thru at the ocean in 2009. Luckily I had reservations at a hotel near by and was able to get 3 good days of hunting in.... You could not dig a target ...then Pinpoint it for there were so many shallow good targets. By the 4th day it was hard to even find a signal sand was coming in so fast.

Video is a little rough ....I was one of the first 5 to do Youtube metal detecting videos and you can tell by the cam video...quality. NOthing like the Go Pro's they have now days..but it is a saved memory.

Great detecting skills. You learned the Minelab well, limiting your junk to a minimum.

I'm finding that i have the most luck searching after really high tides.. even if there was nothing to be found the days before, the high tides seem to remove just enough sand to get a bit deeper.. I've also noticed that along a few beaches here the sand gets stripped from one side and deposited further along the other side.. these beaches are constantly moving and i've found they're the best for detecting as objects don't get a chance to settle too deep to detect..

      The GPX used for most of the hunt today on a beach where the coins are deep. All these coins seem to be dropped from the same time frame. The 2 Buffalo nickels and the Standing Liberty Quarter all have no dates. The rest of the coins are from the 40's to the early 50's. It's safe to assume the dateless coins were dropped in that time frame too. Why do I care? Because these coins were from 15" to 20" deep. I can barely get some of that layer. There is plenty of sand below them. That is where the earlier coins rest. Beaches are not empty, we just skim the surface of them. I'm too tired from digging to post all the junk and the more modern coins found. I'm just glad that I could get that many good hits, with all the beach people that were there getting in my way I want the temps to drop so they will stay home and keep warm!!!!!

      Had a nice week. Got to visit middle son; ate too much, got tanned and got some metal with the Excal. Four days of flat water, two of a little chop and one with chop that was tough to work. Did about half slope hunting and half in the water; left the dry to others. What a luxury to be able to clearly see the scoop when shoulder deep in the water!
      Not much jewelry; three pieces of silver (ring, earring and charm) and two gold looking stainless steel. Lots of change 37 Quarters, 34 dimes, 19 nickles and 171 pennies; no foreign coins on this trip.
      Next adventure is to find a spot on the local beach devoid of metal and start over with known targets to set up and learn the AQ.
      Cheers,

      When I’m all in,... I’m all in!!
      A few nice finds and quiet days on the beach add to the All In recipé.
      This Covid-19 has turned tourists into pleasant members of the public that keep their distance. Just the way I like it on my days off.
      So I decided to update my setup and give my trusty pall the CTX a rest, I’m not selling just yet. It will sniff out the good stuff for sure.
      Dry sand and wet sand hunting: Equinox 800 V3 VLF 11”, XP MI4 pinpointer
      Wet sand excavation: Vallon VMH4-VS30/VS20 PI due in somewhere round half november.
      This evening I’m readíng up on the manuals,... lets get down to the nitty gritty!!

      Having only recently started water hunting, I only recently had some success. My my first experience was at the beach at Monterey Bay. It was a low tide at about 10:30 P.M. The waves were crashing on the shore and the noise was so bad that I gave up and started detecting the dry sand. There were several people on the beach and I was separated from my friend and not comfortable with my surroundings. I did manage a nice silver Indian Chief. The Head dress is inlaid with mother of pearl.
       The next attempt was at a beach North of San Francisco, on the way there I looked at the National Weather Service for a forecast, said dangerous surf, don't go near the water. The tide was receding and my friend said we should be just fine. Shortly after we got there it started to rain and I was getting wet and cold. About forty five minutes into the hunt, I decided that I wasn't having any fun and started back to the vehicle. I broke the cardinal rule, I turned my back on the ocean. The tide was out about one hundred fifty yards. I was about thirty feet from the car in a paved parking lot when a rogue wave came in and knocked me down from behind. Now I was really wet and cold, this was December. I was using my CTX 3030 and I found that my WM 10 couldn't Swim. I tell myself I'm done with the ocean. I didn't try water detecting again until a few weeks ago. My friend Rob talked me into trying it again at Lake Tahoe. The water was full of people and with the Covid restrictions, I tried to maintain social distancing, that put me out in a depth that I was not comfortable with. The shoreline where people were getting in and out of the water was where the most targets seemed to be. My problem wit that was , the bottom had a steep slope and I was having a very hard time standing on it. Nothing to show for my efforts except some clad. Tahoe is such a beautiful place and the water wasn't cold, it just made for a wonderful day. Not being a person that gives up easily, we went back again. The next trip we went back to a different beach with a beautiful campground. Unfortunately the campground was closed due to the fire danger. That trip the water was still very pleasant. The wind was coming out of the South West and got a little stronger as the day went on. The entry point seemed to be where the targets were and that is where the waves were breaking. I did manage a silver Rosie and three Wheaties. As I mentioned the wind was blowing harder and the waves were getting larger to the point I was getting worried about getting knocked down. I changed my M. O. and borrowed Rob's waterproof headphones and tried it some more. Well I guess I got a little too comfortable, it happened again. The wave action knocked me down and started pulling me off shore. I managed to get back up with the help of Rob. By that time I was pretty beat up and decided to call it a day. I decided to try it one more time. We loaded our truck camper and headed back to Tahoe, the fire danger was not as bad and the campground was open. We managed to get a spot for two nights. It takes about 2 1/2 hours to get there, so there was only a few hours detecting the date of arrival. This trip I had a life preserver jacket and some chest waders. The lake was flat and the temperature was still very tolerable, just perfect for detecting. Lake Tahoe is an awesome place and one can only appreciate the beauty of the place by going there. I am absolutely disgusted at the way people trash the place.     Well this trip was different, I got my first gold in the water!  A 14k with "I Love You" inscribed in it. After we got home from a very nice trip, a very dear friend got a hold of me and asked if I would try to find her husband's wedding ring. He was one of my partners in a mining claim and he passed away from cancer about a year ago. She said that she had been working in her yard, cut a lot of shrubs, raked them up put them in a bag and hauled them to the dump. She had spent quite a bit of time looking for it and was almost certain that was forever gone. After the description she gave to me of the ring, it sounded just like the one that I had found at Tahoe. I told her that if I couldn't find it, I would gladly give her the Tahoe ring. It only took about ten minutes to find that ring, it had that "sweet fifteen low tone. That was a very emotional moment for both of us"

      Last night I went to a beach that yielded a lot of targets.  On my 6 hour hunt from 8 PM to 2 AM I got 51 quarters, 40 dimes and nickels, 54 pennies (one wheat), 2 silver rings and one 10k gold ring.  There should have been more rings!  The trash was another 50 pieces or so.  When you figure it is 4-5 scoops per target (1000 total) then it adds up to a stiff back in the morning.
      I found the gold ring 2/3rds of the way through the session about the time the fog started rolling in which made for an enjoyable sight as it covered up the normal lights but there was still a mostly full moon above.  I was using the 15 inch coil and when I started I was down a couple of notches from full power.  I thought there would not be much on the beach but I was wrong and kept pushing along finding some high cuts.  Near the end of the session the detector was nearly out of power and I could hear a lessening in my headphones.
      Something I've wanted to say about the 3.0 update is that it really makes the quarters crackle.  I don't think I remember them like that before and I wish they would be a little more 'solid' but perhaps it is because of the sandwich metals.

      I spent a couple hours after my chiropractor appointment yesterday hitting the wet sand with a dropping tide.  I did dig a .925 loop earring and a copper wire ring with beads but these lobster trap pieces were driving me crazy.  Especially the more rounded one that is an unbroken more or less circle.  I would have almost bet OBN's YTD ring finds that it was a ring or at least anything but a piece of vinyl coated wire.  Small nails can be rejected easily but these pieces of vinyl coated (hence lack of rust) lobster traps are a different animal.  I tried for a while to get the correct Rejection for them but thought that since I was being so unsuccessful I would appeal to higher power.  Yep, that means the folks on the forum that have years and years of experience with these deep, great sounding pieces of "...." trash!  I at first thought I could just dig them and get them off the beach but they seem to multiply.  Are they alive and reproducing?  Geez Louise, I can't tell you how much I hate these things.  
      Ok, my rant is over!  Now for some suggestions on settings that might help ID these damn things.  I am open for any suggestions for settings on my AQ to give me a hint that these time and energy consuming little devils are under my coil.  I have been running mostly just the presets but have run the reject all the way up and down the scale along with the ATS, Sensitivity, and swing speed.  I cannot seem to find a crack in the combination that gives me any type of a hint that there is a nuance to ID these little piece of ferrous garbage. 
      Help!!!
       
      thanks,
      Joe
