Day 6: Metal Detector
Earth is pushed up and snowy mountains appear
Rock crock, split and fold forming channels far and near.
From the deep they are filled with quartz and some gold,
Weathering sets them tumbling downward in the cold.
Bashed to and fro in a vibrant mountain stream,
Gold flecks fall out from the quartz boulders clean.
In the calmer sandy stuff of a riverbed mud,
Gold accumulates deep to beat the panner's blood.
In cold water fresh but with freezing hands,
They test the riverbed with their prospector's pans.
A bucket of dirt is reduced to a few flakes,
The gold light gleaming is the best of effects.
Weeks and weeks for just a few grams,
A bag full of gold powder is the prospector's plan.
meet at about 8 am for helicopter flights to start the day and TV episodes
off. Weather looks good and soon we are off up in the air and heading
over the Glacier and over the peaks besides Mount Cook. We head out over
the plain below the Glacier and on to the sawmill which will be our base.
30 mins of extreme excitement, wondrous views, blue ice and helter skelter
rides. Also saw the best ever glory around the shadow of the helicopter
when we passed through an amazing fog bank covering a prehistoric-looking

were introduced to the challenges. Mine was to make a metal detector using
parts from old radios, Kathy and Mike L to make an accurate balance to
measure the gold we get while Mike B and Ellen were to pan and sluice
The day goes very
well but I do think however that it's going to be really hard to
get the metal detector done in just 2 days so that it can be used on the

first work was to salvage as many useful components from the radios as
possible. I plan to build the main electronics for the metal detector
on a makeshift plastic board from the lid of a Tupperware box and make
use of one of the smaller radios (called an AK44!) to use as an audio
amplifier for the speaker.
Also managed to cut
out the wooden circles for the search coils and fixed them up using cable
ties. Added 20 turns of copper wire and fixed it to a handle upon which
I fixed two plastic Tupperware boxes for the battery and components (to
keep dry). Had a classic Rough Science problem of not being able to cut
and drill because of filming going on nearby. Still, things seem to be
going OK so far.
