Digging wet sand question

Post by Apricot Lil » Tue May 30, 2017 10:22 am

Hello Everyone,
We had another pleasant trip down at Worthing on Sunday evening. Beautiful weather and not too busy by the time we arrived at around 6pm and a rather tasty portion of chips to keep energy levels up.
Optimistic as ever we headed onto the beach. The tide was all the way out, could barely even see the sea so lots of wet sand exposed. Setting aside issues of false signals due to mineralisation we did get a couple of positive sounding 'beeps' that we decided to try digging. We soon realised that we were on a dig to nowhere - the hole just kept filling up with water, the sand collapsing back in on itself and our target, I suspect, was continually dropping further down, always just out of reach.
Is there a trick to digging successfully in these conditions?
We were using our homemade sand scoop and a spade:

We didn't find much else on our trip, just 20p and this (Garrett Carrot for scale):

After getting rid of all the material it was encrusted in we realised it's just part of a groyne, but we were quite excited when we first dug it up. :D

When you dig a hole in saturated sand it fills with more salt water from the surrounding sand.

This does two things. Liquefaction happens in the hole and the artefacts sinks. The added salt content means the hole itself becomes a target.

Try digging a hole that fills with water anywhere on beach then scan over the hole chances are it will beep unless you are using a PI or multi frequency machine.


I use a border spade.

I very carefully pinpoint the target.

Deeper targets

Place the spade vertically 6-8" behind the target

Place my foot right up behind the spade.

Using my foot as a pivot point I quickly arc the spade point upwards and throw the spoil forwards with a quick flick of the foot. 90% of the time It will be out of the hole and on the surface. If it fails I stand at 90° and start again this way when it comes out of the hole you only have one lot of spoil to use your pinpointed on

If the target is shallow I just scoop the top layer off. I don't dig a hole that the target will sink into.

With a spade it takes practice and you have to be quick.


Your bolt looks like its from a Groyne or pier

The Ace 250 is useless for those areas of the beach really. It's ok for dry sand though. You have to reduce the sensitivity down to almost the lowest setting to stop the majority of the falsing, and getting coin sized targets deeper than about an inch or so is basically just luck. Might be worth looking into a different machine if you're keen to detect those areas regularly.

If you like the Garretts then an AT Pro is ok. Or you could look at the older Minelab machines, they're a bit heavier though but some are cheaper too. PI machines are also an option but the lack of discrimination on most means they're not easy to get to grips with.

A cheap spade is a decent tool for the beach. ::g

Thanks for your input hiho,
I realise the issues that the Ace 250 has with wet sand, my query was more about technique when digging in wet sand. At some point though I may well consider looking into a different detector, one more beach compatible.

Yeah I realised that after I posted it, my brain takes a while to wake up sorry. A plastic scoop isn't much use on the wet for any meaningful depth. A long handled metal sand scoop with holes in it is the way to go as you can quickly scoop down once or twice and pull the item out of the hole before it gets waterlogged. With a spade you're more likely to make the item bury itself deeper if you're not quick at retrieving the target. If your beach doesn't have stones/rock to contend with then a scoop is a great investment. ::g There's a few decent ones sold here on the MDF.
I wouldn't recommend making one yourself really, I made my own a while back but it took ages, was a bit cheaper ultimately though.

Yes, I had a look on youtube and saw some videos using a long handled metal scoop which did appear to be very effective. I might look into those further.

Personally I'd go for a spade every time on Worthing beach. That way you can do the reclaimed shingle beaches, the wet sand and the compacted shingle beds in the wet sand. ::g

I like Worthing beach very much and will have to take a spin down there sometime. :D

Yes, Worthing is becoming a firm favourite with us too. Easy to get to, good parking, plenty of beach plus ice cream and fish 'n' Chips. :D
Maybe we just need to practice more on the wet sand with our spade.

I use a evolution 360 sand scoop and a £2 wood handle on it. In the wet u do have to b quick as prev said the hole re fills. Seems like worthing sand is very like mundesley in north norfolk. Generally 3 ish inchs of sand then very fine shingle. The 360 along with the pin pointer is stuff i wonder how i managed with out it. I won't go for the bigger scoop im 6 "2 and 15 1/2 stone and a 360 ccoop full of wet sand is enough. Do u get coins in the shingle ? Ive only found a handfull in the 9 yrs ive been doing the beach. The bulk of the stuff is in the dry soft where i go. I go wonder where it all goes. Does it go really deep in the fine shingle ????? Cheers.

The best bits of Worthing tend to be large beds of compacted 2-6 inch pebbles infilled with a gloopy clay and sand mix. Had some very nice rings and lots of deep fishing weights, coins and the like out of it but a real swine to dig with anything.

Do let me know how you get on with the CTX on your beaches. I promise you that it does work pretty well. I might even pop over from Lynn one evening and show you how it's done! ::g

Apricot lil can I ask if you ever purchased the sand scoop and did it help with the problem of targets disappearing further into the sand

Hi gixer08,
Sorry it's been a while since I've been on here and only just seen your question.
In short, no, I didn't get around to buying a scoop. We were down at Goring last weekend with not much success. That's what brought me back on here looking for advice and now I am seriously considering investing in a decent sandscoop. When the tide is out at Goring there is so much wet sand that I can't even begin to tackle, it feels like a waste!
Of course, the other problem is still that the Ace 250 isn't keen on the wet stuff but we have recently got hold of a Minelab Xterra 70. Perhaps we might have more success with that.
Have you had any good results from beaches?

Hi Apricot lil , apologies but I haven't been on here in a bit also . On the dry sand with the Racer 2 I've found loads of coins but in the wet I'm still losing my targets as they still tend to bury themselves . I trust the detector that there's something there but once I start digging it usually buries itself out off site . Still unsure if a good scoop would be the answer to my problems

Hey gixer08,
Well, having watched loads of youtube videos now of people using them I finally bit the bullet and got myself an Evolution sand scoop. I've yet to try it out on the beach, need to sort out a handle for it first. I'll let you know how I get on though ::g

Just remember to have a spade in the car because scoops don't work well on compacted pebbles (like part of Worthing). ::g

Problem with non dedicated beach machines, is the salt water drive's them crazy. If you get an iron target which is gives a good tone and you start to dig, the machine wil eventuallyl realise it's iron and stop giving you a signal but because the holes filled with salt water, this will give you a good signal now and you'll be digging till Christmas chasing ghost signals.

Hi,
as much the choice of the beach machine is important
the right tool for digging is even more important

especially if you dig deep
you have to stitch vertically on the target
to stir as little sand as possible = less fatigue

for that reason, I think the gamatte is the best
mine, hom made, stainless steel A4 / 3 mm

allows to get targets at 50 cm or more :D

Fred is right and dont take a large spade.............I did a session there last year you can tell the beach has potential but ooooooo boy it is hardcore took me 10 min to retrieve a silver six pence it was a real fight with the sand mixing with the gravel between the large pebbles..........

Good luck

Well we've got a long wooden handle on now so hoping to take it down to the beach this weekend sometime.
LE.JAG, I'm curious about the handle you have at the top. We've got a similar handle to put on ours but haven't yet decided exactly where to place it. I've seen them placed much lower down the shaft than that. Is there a reason you have chosen to put it higher up?
Thanks

the handles at the bottom, are only interesting in the water
and in this case take lighter aluminum

the handle is made of unbreakable fiber, brand leborgne in France ...
and the handle just to drag the gamatte and to shoot when it's deep

if you make a made to your measure
the most important is the angle of the fiber handle on the base
you need to plant it as the picture with my foot
keeping your back straight, this is the most important

preserving your back, you will hold the distance

I use it for several years now
I had to make some stainless steel patches
where he rubs on the sand, who even eats stainless steel...
but still strong

if you do a lot of beach, it's worth going to see a boilermaker
that you will do the same, tailor ;)
