 has 5 search modes designed for different terrains and targets. You can navigate between 

the modes easily by using the right and left arrow buttons. The selected mode will be highlighted in 

black.

Field

Recommended especially for relic hunting. It produces good results particularly on clean 

sites which do not contain waste metal. More depth can be obtained on sites which are 

rocky or trashy, by using the notch discrimination setting and swinging the search coil 

more slowly (one right/left pass per approximately 1 second). 

In this mode, the device produces a low tone for ferrous targets with IDs between 0-15. For non-ferrous 

targets with IDs 16-99, it produces a higher tone which increases in pitch as the coil approaches the 

target. 

PARK MODES:

 These are the 3-tone discrimination modes designed for coin hunting especially in 

trashy sites such as parks.

Park 1

It is relatively deeper but a bit slower than Park 2 mode.

In this mode, the device produces a low tone for ferrous targets with 0-15 IDs,  a 

medium tone for gold and non-ferrous metals with IDs 16-69 and a high tone for 

non-ferrous metals with IDs 70-99 such as silver, brass and copper.

Park 2

In this mode, the device produces a low tone for ferrous targets with 0-15 IDs,  a 

medium tone for gold and non-ferrous metals with IDs 16-42 and a high tone for 

non-ferrous metals with IDs 43-99 such as silver, brass and copper. 

Beach

This is a special mode of the  developed for conductive grounds (salty wet sand 

beach, grounds with alkali soil etc.). The feature of this mode presents the ability to ignore 

iron and similar targets in this group and to be able to perform ground balance on any type 

of ground. While the device performs ground balance in the range of 20-99.9 automatically 

in the other discrimination modes, the device ground balances in the range of 0-99.9 in 

this mode. This enables easier ground balancing on conductive grounds where normally 

ground balance cannot be performed at all or performed with difficulty.

Different than the other modes, targets with 0-15 IDs are notched out by default and cannot be 

changed in order to ignore ferrous metals or ground noise. In this mode, the device produces a 

medium tone for gold and non-ferrous metals with IDs 16-99. 

Salt water and alkali grounds are significantly conductive due to high ionization and cause effects 

similar to that of iron in detectors. These effects may make it impossible to search for metals with 

a standard detector. Existence of an iron elimination feature in a detector can improve the situation 

but may not be sufficient. 

's beach mode eliminates such effects and ground noise. Aspects to be taken into 

consideration while searching on conductive grounds are explained in more detail in the section 

titled Detection on the Beach and Underwater (17).

All Metal

Different than the other modes, this mode features a threshold tone which is 

continuously heard in the background. You cannot search in the All Metal mode 

without ground balancing. 

In this mode, the device does not discriminate targets and detects them all (metals, mineralized rocks 

etc.). ID of the detected target is shown on the display (except for negative hot rocks) and the same 

audio tone is provided for all targets. The audio tone increases in pitch as the coil approaches the 

target. 

In this mode, the threshold setting for each sensitivity level is optimized to provide the best 

performance on different terrains. You can modify these settings based on ground conditions. 

As the sensitivity is lowered, the threshold tone gets weaker and cannot be heard at the lowest 

sensitivity levels.

We recommend using the All Metal Mode when discrimination is not important and not using it in 

heavy trash areas or areas containing many hot rocks.
