4. Fivoriambe sy fametrahana
Follow these steps to assemble your Garrett ACE 400i metal detector:
- Ampifandraiso ny Coil Search:
Align the search coil with the lower stem. Insert the plastic bolt through the holes on the coil and stem, then secure it with the wing nut. Ensure the coil cable is wrapped snugly around the lower and middle stems.

- Ampifandraiso ny boaty fanaraha-maso:
Slide the control box onto the upper shaft. Secure it using the provided cam-locks. The new cam-lock rings prevent movement and play over time.

- Ampidiro ny bateria:
Open the battery compartment on the control box. Insert four (4) AA batteries, ensuring correct polarity. Close the compartment securely.
- Adjust Length and Arm Cuff:
Adjust the length of the shaft to a comfortable height, allowing the search coil to be parallel to the ground when you are standing upright. Adjust the arm cuff for a snug but comfortable fit on your forearm.
- Connect Coil Cable:
Plug the search coil cable connector into the corresponding port on the control box. Ensure a secure connection.
5. Torolàlana miasa
Familiarize yourself with the control panel and its functions before beginning your search.

5.1. Mamelona/Mamono
Tsindrio ary hazòny ny fahefana button to turn the detector on or off. The detector will power on in the last used search mode.
5.2. Understanding the Display (LCD)
The large LCD screen provides crucial information:
- Kisarisary ID kendrena: Indicates the probable target type (e.g., Iron, Foil, Nickel, Zinc, Copper, Silver).
- Digital Target ID (1-100): A numerical value representing the target's conductivity. Higher numbers indicate more conductive targets (e.g., silver coins), while lower numbers indicate less conductive targets (e.g., iron).
- Famantarana ny halaliny: Estimates the depth of the target in centimeters (5cm, 10cm, 15cm, 20+cm).
- Famantarana ny haavon'ny bateria: Mampiseho ny faharetan'ny bateria sisa.
- Tondro fahatsapan-tena: Displays the current sensitivity setting.
5.3. Search Modes
The ACE 400i features five pre-programmed search modes. Press the MODE button to cycle through them:
- Zero-Disc: All-metal mode. Detects all types of metal without discrimination.
- Firavaka: Designed to ignore iron and small trash items, focusing on jewelry.
- Custom: Allows you to create and save your own discrimination pattern. Use the DISCRIM SY V/X buttons to adjust the NOTCH segments.
- vola madinika: Optimized for coin hunting, typically discriminating against iron and some foil.
- Relics: Designed to find relics, often with minimal iron discrimination, as many historical artifacts contain iron.
5.4. Fanitsiana ny fahatsapana
Ampiasao ny fahatsapana bokotra (+ SY -) to adjust the detector's sensitivity. Higher sensitivity increases detection depth but can also lead to more false signals in mineralized ground or areas with electrical interference. Adjust as needed for stable operation.
5.5. Discrimination (NOTCH and Iron Audio)
- NOTCH Discrimination: In Custom mode, you can eliminate specific target segments from detection. Use the DISCRIM button to move the cursor and V/X to toggle segments on/off.
- Feo vy: Tsindrio ny IRON AUDIO button to activate this feature. It allows you to hear discriminated iron targets at a low tone, even when they are notched out. This helps in identifying complex targets (e.g., a valuable non-ferrous target next to iron) and avoiding large iron objects.
5.6. Fanitsiana matetika
The ACE 400i operates at 10 kHz. If you experience interference from other detectors or electrical sources, press the FREQ ADJ button to slightly shift the operating frequency, which can help mitigate interference.
5.7. Pinpoint Function
Once a target is detected, press and hold the manondro button (target icon). Keep the coil steady over the target. The detector will emit a continuous tone, and the signal strength indicator on the LCD will help you center the coil directly over the target for precise location.
6. Fikojakojana
- Fanadiovana: Wipe down the detector with a damp cloth after each use. Do not use abrasive cleaners or solvents. The control box is rain-resistant but not submersible.
- Coil Care: Always use the search coil cover to protect the coil from scratches and impacts.
- Fanoloana bateria: Replace batteries when the low battery indicator appears. Remove batteries if storing the detector for extended periods to prevent leakage.
- fitahirizana: Store the detector in a cool, dry place. Avoid extreme temperatures.
7. Famahana olana
| OLANA | Antony mety hitranga | vahaolana |
|---|---|---|
| Tsy misy hery | Batterie maty na diso napetraka | Soloy ny bateria, ho azo antoka ny polarity marina. |
| Erratic signals / False signals | High sensitivity, electrical interference, highly mineralized ground, loose coil cable | Reduce sensitivity, use Frequency Adjustment, tighten coil cable, try a different search mode. |
| Poor depth detection | Low sensitivity, highly mineralized ground, small target | Increase sensitivity (if stable), sweep slower, ensure coil is parallel to ground. |
| Pinpoint not accurate | Sweeping too fast, not holding coil steady | Slow down sweep, hold coil motionless over target when pinpointing. |
