Turn Seawater On/Off; Target Separation; Low Trash; High Trash - Minelab CTX3030 Instruction Manual

NOTES
With Seawater on, keeping your
sweep speed as fast as possible
will provide maximum depth.
Most beaches are non-mineral-
ized, therefore greater depth can
be achieved using the highest
stable Manual Sensitivity setting.
DO NOT Ground Balance at the
beach – leave GB disabled.

Turn Seawater On/Off

1. From the Mode Settings menu, use the down arrow button to highlight the
Seawater option and press Select.
A green tick will appear in the check box indicating that the Seawater setting is on.
2. Select the Seawater option again to remove the green tick and turn Seawater off.

Target Separation

Range: Low Trash/High Trash/Ferrous-Coin/Ground-Coin
Target Separation allows you to optimize the signal processing to suit your
detecting conditions. The Target Separation settings are:
• Low Trash – targets in a low trash density environment
• High Trash – targets in a high trash density environment
• Ferrous-Coin – coins in a high density FE trash environment, low mineralization
• Ground-Coin – coins in ground with high mineralization

Low Trash
The Low Trash setting provides very stable Target ID's in areas with low trash and
low to medium levels of mineralization. This allows you to create very narrow
discrimination patterns for specific targets.
Using the Low Trash setting in High Trash areas is not recommended because a
strong rejected target in close proximity can cause a good target to be masked or
hidden. The Low Trash setting will respond to whichever target has the strongest
target signal and will ignore the other target.
High Trash
The High Trash setting can identify weak accepted target signals amongst rejected
targets even if the rejected target signals are stronger. The advanced signal
processing takes the best accepted target signal and ignores all the rejected target
signals no matter how strong they are. When High Trash is used, the Target ID is
less stable, therefore a larger edit frame will be required in order to accept or reject
specific targets. High Trash can also be used with a slightly faster sweep speed,
making it suitable for areas where fast ground coverage is important, such as during
competition hunts. The High Trash setting also offers improved target ID stability in
highly mineralized ground conditions.
