How It Performs On Each Terrain

🏖 Beach Detecting
One of the best beach detectors ever made for wet sand and surf zones. PI ignores salt completely and reaches deep into the sand.
🪙 Gold Prospecting
Very capable in heavily mineralised goldfields where VLF detectors falter. Not as sensitive to small nuggets as dedicated nugget shooters.
🌱 For Beginners
Absolutely not for beginners. No discrimination means endless digging and the learning curve is steep.
🪙 Coin Shooting
Will find coins but gives no indication of target type. Not recommended for coin shooting where discrimination matters.
🏹 Relic Hunting
Excellent for deep relic hunting in mineralised conditions. PI’s ground-ignoring ability lets it reach targets VLF machines miss entirely.

Garrett Infinium LS: Owner's Reference and Setup

The practical detail behind the review: the coils, the deep-water rating and the questions owners ask most. This is an older discontinued pulse induction machine, so the reference reflects that. Checked against Garrett's listings and the wider owner community.

Best accessories for the Garrett Infinium LS

  • Submersible headphones Required to reach the full waterproof depth, since the standard package is not rated as deep on its own.
  • A coil cover Cheap protection for the large 10 x 14 inch coil.
  • A harness or bungee Keep the machine going on long remote trips.
  • A spare battery pack Keep the machine going on long remote trips.

Coils that fit the Garrett Infinium LS

CoilTypeBest for
10 x 14 in Power DDPulse induction DDGeneral purpose, the coil supplied as standard
10 x 14 in MonoPulse induction MonoLow-mineralisation ground for extra depth
8 in MonoPulse induction MonoSmaller targets in low-mineralisation soil

The Infinium LS was discontinued (2002 to 2015, replaced by the ATX), so its coils are no longer made. Buy any coils with the machine and check condition, since replacements are hard to find.

Headphones and audio for the Garrett Infinium LS

The Infinium LS uses waterproof headphones to reach its full depth rating. Plan the audio around genuine underwater use.

Best settings for the Garrett Infinium LS

  • This is a pulse induction machine with ground balance rather than a discriminating VLF, so expect to dig more and rely less on target ID.
  • Ground balance carefully for the conditions, since PI depth depends on it.
  • Use the mono coil in low-mineralisation ground for extra depth, and the DD coil in trashier or more mineralised ground.
  • Run at a steady swing; PI rewards patience over speed.

Firmware and manuals for the Garrett Infinium LS

There is no user-installable firmware for the Infinium LS. It is a fixed, older control box.

Garrett's Infinium LS manual is still available in their archive and third-party manual sites; use it for the ground balance and threshold setup.

Garrett Infinium LS: common questions

How deep is the Infinium LS waterproof?

It is a fully submersible machine rated to 200 feet with the optional submersible headphones, so it is a genuine deep-water and diving detector.

Is the Infinium LS still worth buying?

Only for a specific job. It is a discontinued pulse induction machine with hard-to-find coils. For most detectorists a modern multi-frequency VLF is more practical.

Is the Infinium LS good for coins in a park?

Not ideal. As a pulse induction machine it has limited discrimination, so it suits gold, relics and deep-water work more than trashy urban parks.
