Ask a question about this product

With the awesome bonus item packages you guys have, do the trowel and the pin pointer come with holsters for them too?
Question by: Adam Gonska on Feb 5, 2019, 7:13 PM Link
The Z-Lynk pointer DOES include a small belt-holster, but we don't have one specifically for the smaller trowel. We find that this pouch is popular as it will hold the pointer, as well as a trowel (and whatever else you come across).
Answer by: on Feb 6, 2019, 10:00 AM
I see the wireless headphones but does this package include the transmitter as well?
Question by: Hank Sliski on Feb 12, 2019, 12:57 PM Link
The AT Max already has a built-in Z-Lynk transmitter, so you do not need any extra parts to use the wireless headphones or pointer.
Answer by: on Feb 14, 2019, 9:52 AM
What is the maximum depth of this device for large target? It can detect gold inside magnetic rock?
Question by: RJ on Mar 12, 2019, 7:52 PM Link
The maximum depth on this detector is about 12-14 inches or so, depending on ground conditions as well as the size of the target. While it's able to detect gold, if you're primarily looking for gold nuggets, you'll want a detector that specializes in that application. Check out this one:
Answer by: on Mar 13, 2019, 2:06 PM
I'm interested for this metal detector, but I didn't saw on what depth it can scan.
Question by: vladimir on Oct 7, 2018, 3:41 PM Link
This detector has a maximum depth capability of approximately 12-14 inches, maybe even deeper when using the larger 13-inch ultimate coil.
Answer by: on Oct 10, 2018, 10:44 AM
What temperature can the Garrett AT MAX withstand.
Question by: Billy Robinson on Oct 9, 2018, 9:22 PM Link
I'm not aware of any specific temperature thresholds for Garrett metal detectors. You may want to contact Garrett directly, and they should be able to tell you the range.
Answer by: on Oct 10, 2018, 10:56 AM
Is it fully waterproof? If so, how deep under water can it safely go
Question by: Nick on Mar 18, 2019, 10:39 PM Link
Yes, this detector is completely submersible. It is rated down to 10 feet.
Answer by: on Mar 19, 2019, 10:50 AM
Does the AT MAX PRO require updates and can you substitute the corded head phones for the wireless?
Question by: Joe Ilbery on Nov 19, 2018, 6:57 PM Link
The AT Max does not offer software updates. It already comes stock with wireless headphones, so there would be no need to upgrade.
Answer by: on Nov 20, 2018, 10:01 AM
Regarding the coils, what’s the difference? Is there specific scenarios when I should use one over the other? Or is the 13” an upgraded one and I should just use that one all the time?
Question by: Jeff on Dec 3, 2019, 8:23 PM Link
The stock coil is a great option for all-around searching. The additional 13-inch Ultimate search coil is a great option for better depth and ground coverage, although the stock coil may be better for target separation.
Answer by: on Dec 4, 2019, 12:24 PM
Do you get the garret propointer at? It does say you do it only shows a picture.
Question by: Patti on Dec 20, 2018, 3:00 PM Link
Yes, we do have the Z-Lynk pointer listed in the product description- this kit includes the wireless Z-Lynk PRO Pointer AT, as well as everything else pictured with the device.
Answer by: on Dec 20, 2018, 3:37 PM
I live at the beach. Does it work well around wet sand and in salt water?
Question by: Jim Vail on Jan 4, 2019, 12:39 AM Link
Yes, this model is able to balance down to salt-water.
