Water Detecting At Beaches With No Tide

Recommended Posts

Hi all,

I've been doing a bit of reading on strategies for detecting at the beach and some general advice I've found is to go where there are areas of erosion or where the sand is lower.  At a local beach I go to, there is no tide. Does that mean the rings sink to the bottom only to remain inaccessible? Do you think its better to skip water detecting at these beaches in favor of ocean beaches with more current?

Hunting lakes and rivers I'm assuming thats what you are talking about? the depth a  target sinks depends on the density of the soil under it in these areas. Soft mushy bottom obviously targets will sink beyond the detectors capabilities over time. However you have the advantage in these areas because there is no tide or wave action to bring sand in and cover the targets.  I have good luck in fresh water rivers and lakes and I would not overlook these areas. Detecting salt water beaches when the beach has eroded is what most of us are looking for.  Hunting after a big storm  can sometimes provide great detecting opportunities but you need to be ready to drop everything and go when this happens. You dont need a storm to provide erosion however so look for places where the tide has been pounding away making a steep slope or a cut in the beach. Good luck! heres a guy that got on it...

Hi Brian… and welcome to the forum!!! In addition to "no tide" you didn’t mention whether you are anticipating detecting small freshwater lakes with little or no wave action or larger lakes with wave action. So I’ll address both scenarios to supplement what has already been said above.

Success at the small lakes will depend on day-use bather numbers and on the type of bottom substrate. The bottom substrate could range from a hard clay or hardpack gravel bottom that will hold targets, to some combination of soft mud, silt and sand mixture that allows targets to quickly sink out of detection range. If the latter, and bather usage is reasonably high, you may need to detect these on a regular basis while the targets are still detectable. Try these sites and your experience will dictate whether they are worth your time and effort. 

Many freshwater pond and river “swimholes” have been around a long time, and may or not see much present day usage. It could very well be a case of cleaning it out on a one-time basis and moving on to other productive sites. Again, your on-site experience will help you with that decision.

We search generally larger lakes here in Ontario, that do have good wave action as a result of the prevailing winds and of course from summer heat that develops on-shore breezes. These factors facilitate the creation of a series of sandbank-trough-sandbank-troughs in the lakeshore shallows, sometimes extending out to shoulder depth, but that also conveniently run parallel to the shoreline. 

The sandbanks tend to be hardpacked such that small rings remain detectable for several days to several weeks, whereas coins and tokens typically remain within detection range for a much longer duration. The troughs are normally clay-gravel hardpack swept clean by water action, hence all targets remain detectable for many years subject of course to any sandbar movement over extended periods of time. We hunt these troughs routinely because they’re wonderfully productive for gold and silver jewelry at high day-use beaches, and incidentally freshwater is much less aggressive with silver coins and jewelry than saltwater. Even nickels lost nearly a century ago surface looking quite presentable as per the photo below.

Most of my jewelry finds are recovered in knee-to-shoulder deep water. Lakies’ rings are more commonly found in shallow waters due to playing with their small children. Men’s rings are much more widely distributed. Sandbanks and the shallows are areas for throwing beachballs and frisbees, and other horseplay. The bottom substrate can play a role too, for example if there are rocky formations near or at the shoreline at a popular beach, those rocks are magnets for men’s wedding bands. 

Now just a word of caution. Stay alert to small storm drains and creeks entering unfamiliar beach areas where you search. Summer flows normally are quite low or non-existent, but immediately after storms or in the early spring these discharge points can be raging torrents that over many years may have hollowed-out quite a steeply-banked underwater channel running out into the lake. Perhaps no issue for bathers, but for a detectorist loaded-up with gear the channel slopes can trap and pull you quickly into deep water.

Water hunting for coins and jewelry as pictured below can be very rewarding particularly if you have access to countless inviting freshwater beaches that exist here in Ontario. But all you need is one good, productive beach that gets a lot of day use bathers and you can return at regular intervals and do quite well. Good luck Brian, and please don’t forget to post about your adventures to this forum..................... Jim.

I live just north of Boston and when I wrote the post I was actually thinking about the South Boston beaches that seem pretty calm with minimal wave action at least during the summer. The beach I was detecting at definitely doesn't get cuts like that in the video. I have a feeling it may get churned up a little with a Noreaster though.  From what you guys are saying the substrate and the troughs are important. On this beach I was detecting last night up on the sand, the clay was down about 6-8 inches . I have a suspicion the clays is not too deep out the bay itself. Last summer I was getting fouled up by clams. Seems like there was an invasion of them in Revere. 

I had no idea lakes could be so productive, especially up in Ontario where I didn't think people swam in the water as much. I was thinking about trying some beaches in lake Winnipesaukee in New Hampshire. I'm going to try sandy river beaches as well - maybe the St Lawrence river in upstate New York.

I would ask the question: "Are there parking lots near the beaches you are talking about?"  Also: "Do people swim on these beaches?"

If you answer yes to number 2 then go out on a busy day and you will know where people lose their stuff.

      I went out detecting this morning at a couple of local beaches I had not been at for a few months.  I ended up with just a few coins and a couple of silver rings which I have not pictured yet.  It was an enjoyable hunt for 3 hours or so.  It was a leisurely hunt and not an aerobic one for several reasons.  One reason was lack of targets.  You can hunt fast and cover lots of area to a shallow depth or you can slow down and let the coil speed catch some deeper targets.
      During the swinging I was remembering my research for the day about the high tide and the low tide and the wave size and the time of these waves relative to the tides.  I also looked at the black sand line and tried to imagine what stage of the tide/time had produced that and the thought occurred to me that my metal detector was going back in time a few hours.  When you start to think about a few hours then you have to think back longer.  (Maybe even to the last time I hunted that beach.)  On a beach maybe you can think back to the last big energy event, let's say a storm or big surfing conditions.
      When you are a relic hunter on a beach then you look at old pictures to see where there may have been an old bath house.  If you live in that town you start to look for old stores and gathering places like parks and you do research (look back in time) at what may have been lost or deposited there.  When and how something got there becomes the story.
      Sometimes you can slow down and look farther back in time on these sites or locations and that will produce more.  Other times on the beach you have to walk quickly to capture a time before it is washed away.
      Stick with me here ... haha
      When it comes to gold detecting time is still a key factor.  An active wash will have recent gold.  All placers are affected by the recent and distant past.  A placer that has been worked or pushed 100 years ago will have other 'time of deposit' factors involved.  Research and finds will determine how far back and which geological occurrences need to be targeted.  Glacial deposits and all other types of gold deposits are related to time and energy.  You get the idea.
      How far back we look in time depends on how slow we go as one great factor.  It is not the only one but in many places a greater depth can mean a more distant time.  Slowing down may also make smaller targets visible if that is what you want.  (As Jasong has pointed out, small gold and going slow is not always beneficial in paying the bills.)
      Looking back at this it all seems rather 'obvious' and I feel like deleting all of it but maybe this will trigger something in someone out there and allow you to relate to the 'time machine' concept of metal detecting.
      Now it is time to take my son to the beach.  I can see time when I look at him.

      No gold for me and it's not because I've not been trying...Been hitting some parks around my area and a couple beaches on the river. The ocean is only 1.5 hours away but still I find it hard to get to for some reason.  It's nice to get into the water during the Summer...I was at a beach yesterday and dug about 20 sinkers with my excal.. low tide was around noon and Kids were following me around asking lots of questions...different type of detecting then nugget hunting but you got to work with what you have close to home sometimes.  The crucifix is 925 the two rings are fake but look nice anyways

      Over the last Month I have been doing quite a lot of detecting on my local beaches . 
      I found not as much coinage as I used to as cashless society has well and truly kicked in . But the Gold and Silver less society is way off.
      My total for the last Month other than a few Euro's and other coins was £384.76p , 1 Platinum ring which I found for someone and returned to him . The picture of a ring on its own is the Platinum . 3 Gold rings 15 Silver rings 2 Tungsten rings 1 other that looks like a Tungsten but doesn't say so and a Gold looking Stainless Still ring and a junk ring . I searched for 13 times for around 5 hours . The last picture is of the finds I had today.3 August. 
      That search was during Pride. It shows how the cashless society has ruined coin hunting . There were a lot of people about but in the gaps where people had been it was quiet mostly apart from lots of rubbish. I had £13.57p and 2 Silver rings and a 9.3g 9k Gold Signet ring .
      The 2 notes , the £10 note I found on the way back to the Bus stop and the £20 was from a man that paid me that for trying to find his Gold Wedding ring that I failed to find that day and still haven't found. But will try again when the beaches open up .
      Machines used were the "ET" E.Trac or the "EQ" or Nox.

      Well my Sand Shark is about finished so time to shop for a new dedicated (salt water ) beach detector. This machine will be dedicated to wet sand and/or surf only environment. Currently considering the ATX and TDIBH,, any suggestions / input would be appreciated.............Thanks!

      Hello all, as some of you may know, I’m a very keen water detectorist and the Equinox is my go to water hunting machine BUT, last year after about 40-50 hours of water detecting my Equinox did end up flooding from normal (not exceeding 3m) use.
      From what I have read, this doesn’t appear to be entirely unusual.  My suggestion is a waterproof case for the machine that can still let you to do all the normal things with your Equinox whilst adding little weight.
      I understand this isn’t for everyone but can I get a show of hands for who would like something like this and what it would take for you to consider it?
      At this point the idea is purely just an idea but if there is enough perceived interest I may just make a handful ?
      Cheers, Ed

      I know areas where rings have been lost and, to my knowledge, not found.  I understand a strong storm will relocate a ring.  I also wonder if a ring is lost in 3 foot of water during the low tide, will it eventually work it's way up the beach?  I believe that a man's gold ring will sink in the sand to a harder layer of shells or clay (hard pan layer).  It will remain there until a force of water pushes it either up or down.   I also realize there are small lower pockets of these hard pan layers that cause lead weights and rings to gather as if they were in a concave bowl.   My friend says that through time the rings will be moved higher up with the seasonal sand movements and eventually make it to the wet sand of the b
      I wish there was a way to test items in the surf for verification.
