Anfibio Search Modes

Anfibio Multi has 9, Anfibio 14 has 8 and Anfibio 19 has 5 search modes designed for different terrains and targets. You can navigate between the modes easily by using the direction buttons. The selected mode name will be framed on screen.

General Search Modes (GEN and GEN Delta)

Different than the other modes, this mode features a threshold tone which is continuously heard in the background.
In the GEN mode of the Anfibio 14 and Anfibio 19 models, the device does not discriminate targets and detects all targets (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. This is the typical All Metal mode found in most detectors.
The GEN Delta mode of the Anfibio, in principle, works the same as GEN mode. The difference is that the GEN Delta mode will generate the same tone for ferrous and non-ferrous targets at fringe depths but it will discriminate the shallow ferrous targets by emitting a low iron tone.
Gain, threshold and iSAT settings in these modes are optimized to provide the best performance on different terrains. You can modify these settings based on ground conditions.

We recommend using the GEN modes when discrimination is not important and not using it in heavy trash areas or areas containing many hot rocks.

Tone Discrimination (2 TONE)

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 those that contain waste metals by using the DISC. and NOTCH and swinging the search coil more slowly (one right/left pass per approximately 1 second). DISC. is set to 03 as a default value in the Anfibio Multi and Anfibio 14 models and it is set to 10 in the Anfibio 19. You can modify this value according to the ID of the targets you don’t want to detect.
In this mode, the device produces a low tone for ferrous targets with IDs between 0-15 in the Anfibio Multi and Anfibio 14 and for ferrous targets with IDs between 0-40 in the Anfibio 19 . For targets with IDs 16-99 in the Anfibio Multi and Anfibio 14 and for targets with IDs 16-99 in the Anfibio 19, it produces a higher tone which increases in pitch as the coil approaches the target. By using the T.BREAK feature, you can adjust the break points of the target response tones on the Target ID range.

Tone Discrimination (3 TONE)

This is the 3-tone discrimination mode designed for coin hunting especially in trashy sites such as parks.
3 TONE Mode in Anfibio Multi and Anfibio 14: 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 16-66 and a high tone for non-ferrous metals with IDs 67-99 such as silver, brass and copper.
3 TONE Mode in Anfibio 19: In this mode, the device produces a low tone for ferrous targets with 0-40 IDs, a medium tone for gold and non-ferrous metals with IDs 41-80 and a high tone for non-ferrous metals with IDs 81-99 such as silver, brass and copper.
By using the T.BREAK feature, you can adjust the break points of the target response tones on the Target ID range.

Tone Discrimination (4 TONE)

This mode is present in the Anfibio Multi and Anfibio 14 models. It is not present in the Anfibio 19 model.
4 tone discrimination mode designed for coin hunting in low-medium mineralization. Due to its high gain and depth, this mode is a bit noisier than the other modes. Noise will be more in the air versus in the ground. Take this fact into consideration when adjusting the gain level.
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 16-30, a medium-high tone for metals with 31-66 IDs, and a high tone for non-ferrous metals with IDs 67-99. By using the T.BREAK feature, you can adjust the break points of the target response tones on the Target ID range.

Tone Discrimination (5 TONE)

This mode is present in the Anfibio Multi and Anfibio 14 models. It is not present in the Anfibio 19 model.
This mode is designed for coins hunters who are looking for more separation, especially in regions with a larger variety of coins. Just like the 4 Tone mode, due to its high gain and depth, this mode is a bit noisier than the other modes. Noise will be more in the air versus in the ground. Take this fact into consideration when adjusting the gain level.
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 16-30, a medium-high tone for metals with 31-66 IDs, a high tone for non-ferrous metals with IDs 67-85 and a higher tone for non-ferrous metals with IDs 86-99 . By using the T.BREAK feature, you can adjust the break points of the target response tones on the Target ID range.

99 Tone Discrimination (DI99)

This mode is present in the Anfibio Multi and Anfibio 14 models. It is not present in the Anfibio 19 model.
Multi-tone discrimination mode designed for coin hunting in various mineralization. In this mode, the device produces a low tone for ferrous targets with 0-15 IDs. For targets with IDs greater than 15, the device will produce a different tone for each ID. The tone will be higher in pitch as the conductivity of the metal increases and vice versa.

Beach Mode (BEACH)

This mode is present in the Anfibio Multi and Anfibio 14 models. It is not present in the Anfibio 19 model.
This is a special mode of the Anfibio 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 20-99.80 automatically in the other discrimination modes, the device ground balances in the range of 0-99.80 in this mode. This enables easier ground balancing on conductive grounds where normally ground balance cannot be performed at all or performed with difficulty.

In this mode, the device produces a low tone for ferrous targets with IDs between 0-15. For targets with IDs 16-99, it produces a higher tone which increases in pitch as the coil approaches the target. By using the T.BREAK feature, you can adjust the break points of the target response tones on the Target ID range.

Different than the other modes, the DISC. is set to 15 as a default value in this mode in order to ignore ferrous metals or ground noise.
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.

Anfibio’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.

Deep Mode (DEEP)

Recommended especially for relic hunting, this mode is the deepest mode of the device. Therefore, it may run relatively noisier. Noise will be more in the air versus in the ground. Take this fact into consideration when adjusting the gain level. While searching in this mode, a slower swing speed is required.

The discrimination ability of the DEEP mode is relatively less compared to the other modes. Hence, its performance may vary on trashy sites versus clean ones.

In this mode, the device produces a low tone for ferrous targets with IDs between 0-15 in the Anfibio Multi and Anfibio 14 models and for targets with IDs between 0-40 in the Anfibio 19. For gold and non-ferrous targets with IDs 16-99 in the Anfibio 14 and Anfibio Multi and targets with IDs 16-99 in the Anfibio 19, it produces a higher tone which increases in pitch as the coil approaches the target. By using the T.BREAK feature, you can adjust the break points of the target response tones on the Target ID range.

Cache Mode (CACHE)

This mode is present in the Anfibio Multi and Anfibio 19 models. It is not present in the Anfibio 14 model.
CACHE mode in Anfibio Multi:
In this model, the CACHE mode is a non-motion mode. In other words, the device will generate an audio response when you hold the coil stationary without swinging over the target. The audio response increases in volume as the coil approaches the target. This mode is recommended for larger and deeper metals.

In the CACHE mode, the device will generate the same audio tone for all metals and it will display the target ID on screen. At the same time, the ID scale will fill up to the right in proportion to the signal strength.
Target ID range is 00-99. 00-15 are ferrous and 16-99 are non-ferrous metals. You can discriminate out all IDs below a certain ID by using the DISC. setting and simply avoid these metals in the field.

When the device detects a discriminated metal, it will not produce an audio response or an ID. However, the ID scale will fill up to the right in proportion to the signal strength.

The threshold in this mode is internal and cannot be adjusted by the user. Changes in the ground and temperature may lead to drifts in the threshold. Threshold drifts will be reflected in the ID scale either in the positive way (right side) or the negative way (left side). The device may emit an audible response in the positive drifts but not in the negative ones. When the threshold drifts, press the PP button once to retune the detector. Retuning periodically while searching in this mode is recommended.

IMPORTANT! For a more stable operation, try keeping the coil consistently at the same height above the ground where you retuned the detector.
IMPORTANT! If you retune the detector over a target, the threshold will drift to the negative side and the device will no longer detect the target until the detector is retuned. In addition, the depth of the detector will also decrease.

If the drifts are substantial and retuning does not improve the situation, increase the iSAT to a level where the drifts are eliminated (for detailed information on iSAT please refer to the related pages). As the iSAT is increased, the device may detect weaker signals but will not be able to detect the targets anymore if you hold the coil stationary or sweep back and forth over the target. If the drifts still continue frequently, set the iSAT back to its original value and lower the GAIN. Then, re-ground balance.

CACHE Mode in Anfibio 19

3-tone discrimination mode designed for users who prefer a lower noise level while detecting. Ideal for coin and relic hunting on changing grounds and different levels of mineralization. It will provide weaker responses for fringe depth targets as well as ground and environmental noises. Therefore, it is suitable for use with DISC. set to 0 and at higher gain levels. If needed, a more stable operation can be obtained by increasing the DISC. but discrimination will create a greater loss in depth in this mode compared to others.
