Beach: Optimised for all salty conditions – dry sand, wet sand, surf, underwater
Beach Mode is for saltwater 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 saltwater. 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 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 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 MultiIQ processes a very low weighted multi-frequency combination, using the same algorithms as Beach 1 to maximize ground balancing for salt.
Beach Detecting Hotspots
There are good chances of finding coins and jewelry under jetties and boardwalks, besides steps and entryways 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.
Difficult Areas – Black Sand
The Beach Overload Indicator will appear when the transmit signal strength is automatically reduced. 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.
