QUICK START GUIDE

1.Power ON.

Press and release the ON / OFF Power button. The ACE 400 powers on in the last mode used, automatically adjusts for ground minerals and is ready to search. The detector operates with four (4) AA batteries which are already installed by Garrett. (Factory default mode is Coins.)

2.Select Mode.

Use the Mode button to select a different detection mode, when desired.

3.Adjust settings.

Adjust Sensitivity or Discrimination settings, if desired.

4.Begin scanning.

Lower the searchcoil to approximately 1 inch above the ground and scan the coil left and right at approximately 3 ft/second. The coil must be in motion for target detection, but can remain stationary during Pinpoint.

DETECTOR ASSEMBLY

Loosen lower camlock and extend lower stem. Insert mounting washers, connect searchcoil to stem as shown, and handtighten wing nut.

Loosen upper camlock, insert S-stem with control housing, adjust lower stem to comfortable length, and hand-tighten the camlocks. Wrap cable snugly around the stem with the first turn of the cable over the stem.

Note: The arm cuff can be adjusted by removing the screw on the bottom and moving it to the other hole.

Power ON/OFF—Hold this button for 1 second to turn power ON or OFF.

Factory Reset —To restore factory settings, press and hold the power button for 5 seconds (until the detector produces a fast double beep).

Battery Level Indicator—Shows continuous status of battery life. Replace batteries when 1 segment remains.

Frequency Adjust—While holding down the (/X) button, use DISCRIM (+) or (-) to increase or decrease the frequency setting. Choose from four minor frequency adjustments (F1 to F4) in order to minimize interference caused by electrical sources or other metal detectors.

Digital Target ID

Target ID Legend—Works with the Target ID Cursor to indicate a target's probable identity, with Ferrous (iron) targets at the left, non-ferrous targets that are thin or have low conductivity in the middle, and thick or high conductivity targets (e.g. thick silver) at the right.

Lower Scale—Displays the current discrimination pattern, with lighted pixels indicating accepted targets and blank pixels indicating rejected targets.

Target ID Cursor (Upper Scale)—Will display for every target, but will produce audio only for targets accepted on the Lower Scale.

Digital Target ID—Provides a value from 0 to 99 to identify targets more precisely than the ID cursor.

Coin Depth Indicator—Shows the depth of a coin, or a similar sized target. Note: targets larger than a coin may display shallower than actual depth while targets smaller than a coin may display deeper than actual depth.

The sample chart on the following page provides Digital Target ID ranges of some commonly found items.
