Beach DetectorInfo wanted
Looking to get back into detecting after 10 years. As the beach is
about 100 yards from me looking for some info on what is a good one
for the beach. I used to have an Arado 65 some years ago, wished I
had kept it now as it was good on the beach. Want to use it on the
low tide line as well as on the shingle so a good bit of
discrimination required. Any help greatfully received.
Any one selling a Detector please let me know. Location here is
Worthing.
Regards.
Ivor

Re: Beach DetectorInfo wanted
The best detector for depth and sensitivity on a beach is a pulse induction
machine, I tried one once and I dug down almost 3ft for a coca cola can!
They are ideal for finding rings that have slipped off chilled bathers
fingers in the water below the lower tide line.
The down side with these machines is poor discrimination,
so be prepared to dig up nails, etc.
A friend of mine uses one regularly on holiday beaches and usually come home
with a dozen or so gold and silver rings.

If you keep your eyes peeled on ebay or in army surplus shops, there are
a number of Schiebel AN-19/2 mine detectors knocking about, which are
pulse induction machines made to military (i.e. squaddie-proof) spec.
What you get is a search head with two coils, one concentric inside the
other, and an electronics box with a shoulder strap. These machines have
three controls only; on/off switch, volume and tuning (no cissy
auto-tune motion for the military) and make a continual ticking noise
through the headphones when in use. The ticking isn't a machine about to
die; it is a "confidence tone", designed to tell the operator he isn't
about to blow his feet off because the batteries have conked out.
As Theodore above said, PI machines are deep-seeking and capable of
finding really small stuff (the test target for the Schiebel is a 5x1mm
steel pin, to be found at 5cm deep) but they really, REALLY love iron.
Don't use them inland unless you really deeply truly desire to find lots
of rusty old horseshoes.
On the coast iron rusts away like magic, so you'll find only non-ferrous
stuff. That's the upside; the downside is you'll find tons of ringpulls,
foil, coke cans and even the odd druggies' needle and syringe (dig with
a shovel on a beach, not your hands!) so take a binbag to get rid of the
junk.
A ruling decades ago showed that beaches between mean low water and mean
high water are Crown land, and don't come under the juresdiction of the
local council. That doesn't stop the local numpties passing shedloads of
laws on what you can and cannot do on a beach (silly little buggers do
it to feel all important, you see) but it does stop 'em enforcing it.
However, if you take a binbag and pick up lots of litter as you detect,
you gain the moral high ground and usually local officialdom will let
you off whatever trumped-up charge they think they can land you on.
