Beach

Optimised for all salty conditions – dry sand, wet sand, surf, underwater.
Beach Mode is for salt water beaches including dry sand, wet sand, surf and underwater conditions. The salt that is typically present
causes the sand and water to be very conductive, causing salt noise to be detected. Multi-IQ is better able to reduce this noise than any
single-frequency can. Therefore Multi is the only Frequency option.
Beach Mode specifically identifies any residual salt response and assigns a ferrous Target ID - indicating that it's an unwanted target – so
that desirable low conductive targets (such as gold chains) can readily be detected with minimal interference from the salt water.
The Recovery Speed is relatively high to further reduce unwanted salt-water signals, without greatly sacrificing detection depth.
Beach 1: Wet / Dry Sand
Beach 1 is most useful for detecting in wet/
dry beach sand and also in shallow water where
conductive salt signals are prevalent. It has good sensitivity to
coins and small/large jewellery. Beach 1 reduces the salt signal,
while maintaining high transmit power, and still being sensitive
to desirable targets. Beach 1 Multi-IQ processes a low frequency
weighted multi-frequency signal, and uses special algorithms to
maximise ground balancing for salt.
Beach Detecting Hotspots
There are good chances of finding coins and jewellery
under jetties and board-walks, beside steps and entry
ways to and from the beach.
Locate the areas where people swim the most and
detect in the deeper water there. Venturing into
the water can give you an advantage over other
detectorists who remain on the sand. Research
shipwrecks if you are interested in historical finds.
Occasionally, the top layers of sand will be washed
away by stormy weather conditions, exposing some
deeper layers that often contain good targets.
Beach 2: Underwater / Surf
Beach 2 gives the best results when either wading
or shallow diving, with the coil and/or detector fully
submerged. In these instances, there is a very strong salt signal
present, so Beach 2 has a lower transmit power, which results in
much less noise. This profile may also be useful in dry conditions
where there are extremely high ground noise levels. Beach 2 Multi-
IQ processes a very low weighted multi-frequency combination,
using the same algorithms as Beach 1 to maximise ground
balancing for salt.
Difficult Areas – Black Sand
The Beach Overload Indicator will appear
when the transmit signal strength is
automatically reduced.
Beach | 25
Some beaches contain black sand, which has
high natural iron content and is often
magnetic. This causes continuous false
ferrous detections, making normal beach
detecting impossible.
Beach Mode automatically senses black sand
and reduces the transmit power to ensure
that targets can still be detected without
overloading occurring. When black sand
is sensed, the Beach Overload Indicator
will appear on the LCD. When this icon
disappears, full transmit power automatically
resumes.
