Searching in Shallow Water and Beach
All search coils of the
RACER
metal detector are waterproof. This provides convenient searching
in shallow water and on the beach. When searching around water, be careful not to get the
system box wet.
As explained before, salt water and alkali grounds are significantly conductive and cause effects
similar to iron in detectors.
RACER
’s Beach mode is specially designed for such conditions. You
can perform your search easily using the Beach mode without requiring any special settings.
Beach mode is ideal for wet beach sand. You can use the other modes while performing search
over dry beach sand.
You should consider the following while performing search over wet beach sand or water:
1) When you swing the search coil over the holes you dig in wet beach sand, you can receive
metal signals, this is a normal condition.
2) The search coil may give false signals when going into and coming out of the water so please
try to keep the coil either in or out of the water.
If you filter off the rocks with a correctly adjusted ID FILTER setting in discrimination modes, you
can hear the signal of the target under the rock if the target signal has a slightly greater effect
than the filtered ID. The important thing here is that if you detect a target and dig out a rock, you
should note the ID you got before digging and use it as the ID Filter value the next time.
For instance; the hot rocks in your search field tend to give IDs around 3-4. In this case, you
should set the ID Filter to maximum 5. This way you can eliminate rocks and receive the signals
of metals underneath. If you set the ID Filter too high unnecessarily, you will lose metals along
with rocks.
If the hot rocks in your search area tend to give high IDs, then the chances of missing the signals
of small metals underneath will be high as well.
