Quick verdict

The current Garrett Pro-Pointer AT 1140900 is a sensible choice for detectorists who need a simple pinpointer for wet soil, creeks, shallow-water recovery, and ordinary land hunts. Garrett’s current U.S. product page and its April 2018 manual publish a maximum depth of 20 feet (6 meters).

The catch is unusually important for used and old-stock buyers: Garrett’s 2015 launch material described the same part number as waterproof to 10 feet (3 meters). The published limit changed, but the part number did not. A listing that says only “Garrett 1140900” therefore does not tell you which document accompanied the unit.

Use this decision rule:

  • For a current new unit supplied with current Garrett documentation, follow the current 20-foot maximum and every seal-care instruction in its manual.
  • For a used or old-stock unit with a 10-foot manual, treat 10 feet as its conservative boundary unless Garrett resolves that specific unit for you.
  • If the seller cannot show the model, documentation, or battery-cap condition, do not buy it for deeper submersion.

That answer is less convenient than repeating one number, but it is more useful than pretending dated official documents do not conflict.

The official rating timeline

Document date Exact identity Published maximum What the source establishes
February 2015 Pro-Pointer AT, PN 1140900 10 ft / 3 m Garrett’s launch publication introduced the orange AT at 10 feet.
April 2018 Pro-Pointer AT, model 1140900 20 ft / 6 m, IP68 Manual revision 1538800.D.0418 gives the higher limit and seal-care instructions.
June 2021 1140900 and Z-Lynk 1142200 20 ft / 6 m, IP68 Garrett’s buyer guide rates both versions to 20 feet and separates their wireless behavior.
Checked August 30, 2026 Pro-Pointer AT, PN 1140900 20 ft / 6 m Garrett’s current U.S. product and underwater-category pages repeat the current limit.

The key finding is not merely that an old retailer forgot to update a page. Garrett’s own 2015 launch material and its later manual publish different maximum depths for part 1140900. That makes document date relevant to the buyer decision.

It does not let us conclude that every 2015 unit and every current unit are internally identical. A public buyer discussion includes a reported Garrett email saying the product itself did not change and the rating was raised from a conservative 10 feet. That is useful context and explains the persistent listings, but a copied private email is not a first-party public technical bulletin. We did not turn it into a safety guarantee.

Which number should you follow?

Current new stock

For a new 1140900 sold with the current manual, Garrett’s published boundary is 20 feet. The April 2018 manual also says to keep the battery-cap threads free of sand and sediment and periodically lubricate the O-ring with silicone grease to maintain a tight seal.

“Waterproof to 20 feet” describes a maximum operating boundary, not a promise that a dirty, damaged, cross-threaded, or poorly maintained cap will remain sealed. Check the cap before the first water use and after grit-heavy hunts.

Used or old-stock 1140900

Start with the document that came with the unit. If it is manual revision 1538800.B.0315, the published limit is 10 feet. If it is revision 1538800.D.0418, the published limit is 20 feet. A seller photo of the manual’s specification page is more useful than a copied listing paragraph.

If the manual is missing and deeper submersion matters, ask Garrett about the unit rather than inferring 20 feet from today’s product page. A current page can establish Garrett’s current claim; it cannot date an unknown used pinpointer or prove its seal history.

Wet ground without planned submersion

The rating dispute matters less when the tool is used in rain, wet plugs, mud, or shallow rinse water without approaching either depth limit. Seal condition still matters. Grit around the threads can compromise the closure long before a detectorist gets anywhere near 10 feet.

Standard 1140900 versus Z-Lynk 1142200

These are related products, not interchangeable names.

Check Standard Pro-Pointer AT Pro-Pointer AT Z-Lynk
Garrett part number 1140900 1142200
Published 2021 waterproof maximum 20 ft / 6 m 20 ft / 6 m
Wireless integration No Z-Lynk transmitter Z-Lynk connection for compatible equipment
Fully submerged audio Local audio and vibration Local audio and vibration; Garrett says radio does not transmit through water

Choose 1140900 when you want a self-contained pointer and do not need Garrett wireless audio. Choose 1142200 only when Z-Lynk integration adds something to the rest of your setup. The wireless model does not move the underwater alert into headphones while submerged, so do not buy it for that specific expectation.

The bright orange shell is not enough to identify either version. Match the full name and part number, especially in marketplace search results that mix accessories and visually similar pointers.

What the 1140900 actually gives you

The April 2018 manual lists three sensitivity levels, audio-plus-vibration or vibration-only operation, fast retune, a 360-degree side-scan area, LED light, ruler, lost-pointer alarm, and a single 9V battery. It identifies the operating frequency as 11.5 kHz and the weight as 6.5 ounces with the battery installed.

Those specifications point to a straightforward workflow rather than a feature-heavy instrument:

  1. Turn it on away from metal so the initial tune is not distorted by the target.
  2. Use the proportional response to narrow the location within a plug, hole, or loose material.
  3. Quick-press fast retune when mineralized ground, saltwater, or a broad target response needs to be reduced.
  4. Lower sensitivity if the environment remains unstable.

Garrett also says not to use the pointer as a digging or prying tool. The scraping blade can move loose material, but the case is not a substitute for a proper digger.

Who should buy it

The standard Pro-Pointer AT fits a detectorist who wants one uncomplicated recovery tool across parks, fields, wet soil, creeks, and shallow-water sites. Its strongest case is the combination of simple controls, a current 20-foot published boundary, and a replaceable 9V battery.

It is especially logical when:

  • water and mud are normal parts of the hunt rather than rare accidents;
  • one-button control is preferable to a screen or menu;
  • fast retune is useful in mineralized ground or saltwater;
  • an exact 1140900 identity and current documentation can be verified.

It is a weaker fit when the buyer needs wireless headphone integration, wants ferrous-tone information from the pointer, prefers rechargeable built-in power, or cannot establish the unit’s identity and water-use documentation.

For a wider decision, our best pinpointers for metal detecting compares the Garrett with models whose controls, power systems, and detector integration solve different problems.

The closest documented alternative

The Minelab PRO-FIND 35 is the clearer alternative when 10 feet is enough and five sensitivity levels plus Ferrous Tone ID matter more than Garrett’s current 20-foot boundary. Minelab’s current specification page also lists Detector Interference Free technology, a 9V battery, holster, lanyard, vibration, and a flashlight.

This is a specification comparison, not a hands-on performance ranking. Ferrous Tone ID adds another signal to interpret; it does not identify the recovered object for you. The Garrett keeps the decision simpler, while the Minelab provides more adjustment and an iron-related cue.

Buying checklist for 1140900

Use the full identity rather than the nickname “Garrett Carrot.”

  • Confirm the manufacturer is Garrett Metal Detectors.
  • Confirm the name is Pro-Pointer AT.
  • Confirm the standard part number is 1140900.
  • If the listing promises Z-Lynk, require part 1142200 instead.
  • For used stock, ask for the manual revision or a clear photo of its depth specification.
  • Inspect the battery-cap threads and O-ring condition before relying on any water rating.
  • Treat a missing manual, damaged cap, unknown seal history, or vague listing as unresolved risk.

We could not directly read a current Amazon product page during this review because the public page fetch returned a cache miss. The page therefore uses an honestly labelled exact-model Amazon search for Garrett Pro-Pointer AT 1140900, not a guessed direct ASIN. Match all three identity fields before buying.

Ownership and water-use checks

The useful maintenance rule is narrow: follow the manual, keep the closure clean, and do not improvise beyond the published boundary.

After a muddy or sandy hunt, remove debris without using the pointer as a pry bar or scrubbing it with an abrasive cleaner. Before water use, inspect the battery-cap threads and the O-ring. Garrett’s manual calls for periodic silicone-grease lubrication of the O-ring; it does not justify substituting an arbitrary chemical or ignoring a damaged seal.

Remove the 9V battery for storage longer than 30 days, as the manual directs. A water rating protects a correctly closed, maintained enclosure within its stated conditions; it does not protect against battery leakage during storage or physical damage from misuse.

Methodology and limits

This review was rechecked on August 30, 2026. We compared seven retained sources: Garrett’s 2015 launch publication, April 2018 owner manual, 2021 buyer guide, current product page, current underwater-product page, Minelab’s current PRO-FIND 35 specifications, and one public buyer discussion that documents the real 10-foot-versus-20-foot question.

The retained dataset records five dated rating rows, two exact Garrett part identities, five derived findings, and three buyer decision paths. Material facts link back to their source IDs in the checked-in research file.

This was not hands-on testing. We did not pressure-test a unit, inspect a serial number, authenticate marketplace stock, or verify that every historical 1140900 shares identical hardware. The conclusion is deliberately limited: Garrett’s public maximum changed while the part number remained stable, and an unknown used unit should be judged by its own documentation and condition.

FAQ

Is the Garrett Pro-Pointer AT rated to 10 feet or 20 feet?

Garrett launched part 1140900 with a 10-foot rating in 2015. Its April 2018 manual, 2021 buyer guide, and current product pages state 20 feet. Use the current 20-foot boundary for a current unit with current documentation; keep a used or old-stock unit inside its own documented maximum unless Garrett resolves that unit for you.

Did Garrett change the hardware when the depth rating changed?

The public first-party documents do not answer that question. They keep part number 1140900 while changing the maximum depth. A public discussion reports a Garrett email saying the unit did not change, but we could not independently authenticate that private email, so it is not used as a safety guarantee.

What is the difference between 1140900 and 1142200?

1140900 is the standard Pro-Pointer AT. 1142200 is the Pro-Pointer AT Z-Lynk. Garrett’s 2021 guide rates both to 20 feet, but it says wireless radio does not transmit through water.

What should I check before using one in water?

Confirm the model and its manual, remain inside that document’s maximum depth, clean sand and sediment from the battery-cap threads, and maintain the O-ring as Garrett directs. If a used unit’s history or seal condition is unknown, resolve that uncertainty before submersion.
