Ace 400 Features and Benefits

The Garrett Ace 400 is a metal detector with dozens of features that can make your hunt enjoyable and successful. They include:

1. Three-Tone Audio System

The machine offers a 3-tone audio system that produces three distinctive tones to match the metal’s conductivity. These are:

  • Beltone: It notifies you when you find a high conductivity treasure.
  • Medium or low-pitched: The tone goes off when you have found a low conductivity material.
  • Pulsewidth modulation: It is highly responsive audio that makes it easier to use the metal detector.

2. Iron Discrimination and Audio

One great feature of the ACE 400 is the iron discrimination and audio, which is not present in the discontinued ACE 350. It is a tech that enables you to hear the iron trash so you can pick up treasures covered by iron. 

The setting also helps to block “ghost signals” to avoid unnecessary digging.

3. Digital Target ID

The ACE 400 comes with a digital Target ID with a scale of 0-99, meaning that you enjoy more accurate results. Instead of the machine informing you that you have found a coin, it tells you have discovered a clad or silver coin. 

Some notable numbers include:

  • 87-90 for clad quarters
  • 83-85 for a clad dime
  • 42-45 for a clad nickel
  • 77-80 for a clad penny

4. Search Modes

The notches allow you to fine-tune the detect to ensure that you ignore some targets. With that said, you get five preset search modes, which are:

  • Relics: It helps to remove smaller iron targets while finding lower conductivity treasures. These include lead, brass, and bronze.
  • Jewelry: The feature gets rid of iron trash while finding better targets like rings, necklaces, and bracelets.
  • Coins: The feature enables you to eliminate foil, pull-tabs, and other trash when finding coins.
  • Zero-disc: It is not an authentic all-metal setting, but it allows you to discover all metals without getting rid of iron.
  • Custom: You can program your search mode using the custom mode. That is possible because you get to reject/accept discrimination buttons.

5. Waterproof Search Coil
