How far do things move?

Post by Bids » Thu Mar 28, 2013 8:24 pm

Hi everyone
I was just wondering when something is lost at the beach does it stay in that area or is it likely to move a lot? Say a mile up the beach!
I know people say to detect the busier parts of the beach but I'm trying to think out of the box, and maybe detect the less busy parts that other people wouldn't bother with :D

Good idea? Or just over thinking? x;

I think here was a post some months back.. A guy marked 10 coin and dumped them to track movement in situ... I try to se if I can find it.. ::g
Also ocean current and local weather conditions will be big factor..

It's all to do with Longshore drift ... Some things may stay where they were dropped (Perhaps if alot of sand covered it in a short amount of time) and it hasn't emerged since, but most things would have moved ::g

Things tend to move in the direction of the long shore drift, and get sorted out in groups of coins, of the same weight.There are so many things that can effect this one of the hardest things to sus out are the moment of beach finds when you sus this out you will have cracked your beach.Then you go to a new beach and you will have to start all overagain this why beach detecting is so addictive.

I tend to look for the patches of coin-sized pebbles. If they got there, then there are probably some coins etc. in with them ::g

This is always a difficult question to answer and can depend on both national (east or west coast) and local conditions. The bits of molten aluminium from Weston-Super-Mare pier (3 years ago) have drifted south to Berrow and north to Clevedon - probably due to the high tides in the area. I have been detecting Clevedon beach and have been finding a few small pre-decimal coins (occasionally on the surface) within a small area and can only assume they have been locally dropped rather than from up and down the coast and brought to the surface by wave action on the pebble beach.
The two points are contradictory (and probaby not very helpful), but it does go to show that longshore drift can only explain part of the explanation of the movement of items on the beach.
My final advice is to study the local beach carefully and try to glean as much information / evidence that you can on the action of drift / wave / wind action on the beach. The following website has lots of useful information from an experienced beach detector...

As Tomo says "All beaches are different" I am therefore of the opinion there will be no set pattern.
