If you are performing a search in the All Metal mode, monitor the ID produced by the
device. If the ID provided by your device is close to the rock and iron zone, it is quite
possible that you detected a target under the rock. Since ID FILTER cannot be used in the
All Metal mode, you need to discriminate by taking the value on the display into
consideration.
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.

Searching in Shallow Water and Beach
All search coils of the
RACER 2
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 2
’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.
