Nokta AU Gold Finder Officially Introduced

Recommended Posts

Anyone have any insight on this new machine from Nokta? Saw it advertised on a internet discount detector sales site (guess.....yep that's the one), kind of looks like a "futuristic GB2". Man this company never sleeps.

The Nokta AU Gold Finder was originally mentioned on the forum back in January.

It is basically a 56 kHz Makro Gold Racer circuit put in a highly water and dust resistant (IP56) housing reminiscent of the Gold Bug 2. It honestly kind of reminds me of what a Gold Bug 3 might have been if Fisher had ever made one. Super hot on tiny gold, variable disc, option to use ground tracking, ground grab, or manual ground balance - and more. There is a dual tone ferrous/non-ferrous mode, and a red LED (ferrous) green LED (non-ferrous) visual id system. The control box contains the batteries and is easily removed from the rod for belt mounting with the integrated belt loops. Runs off four AA batteries.

This should really appeal to those who are not fond of all the digital menu nonsense and who prefer to flip a switch and tweak a knob. Comes with both 10" x 5.5" DD coil and 5" round coil (both with scuff covers) for $749

I am not sure what the distribution will be on this one - my understanding it was built specifically at Kellyco's request so may be exclusive to them. I do not see it on the Nokta website. I am building an information page here.

From the Owners Manual:

Nokta AU Gold Finder Search Modes


ALL METAL is the deepest detection mode. Different than the discrimination modes, this mode features a threshold tone which is continuously heard in the background. ALL METAL mode detects all targets (metal, mineralized rocks, etc.) and provides a single target tone for any target detected. When ALL METAL mode is selected, the detector does not discriminate between differing target types. The volume and the tone increases in pitch as the coil is moved closer to the target. The default values for DISC. FILTER, SENSITIVITY and iSAT will provide the best performance for a variety of ground mineralization conditions. Fine tune (adjust) these settings to account for variations ground conditions for each location being detected.

Discrimination Modes (DISC.1 FAST / DISC.2 DEEP)

DISC modes have common performance features. They discriminate varying metal targets, but perform differently based on ground conditions in the area being detected as described below:

IMPORTANT: When using DISC.1 FAST and DISC.2 DEEP, sensitivity level must be properly adjusted so that the detector is silent when no metal is present under moving coil. If you hear crackling sound in DISC modes, the SENSITIVITY is adjusted too high and must be gradually reduced until no sound is heard.

No Threshold will be heard when using DISC.1 FAST and DISC.2 DEEP. The Au GOLD FINDER will provide audible response only when target is detected.


DISC.1 FAST is a 2-tone discrimination mode designed for use in gold fields with high mineralization or significant quantities of conductive hot rocks. DISC.1 FAST provides slightly less depth performance but significantly improved target detection and recovery speeds in trashy and/or highly mineralized soils when compared to the other modes.


DISC.2 DEEP is a 2-tone discrimination mode designed for use in gold fields with less mineralization and/or minimal quantities of conductive hot rocks. DISC.2 DEEP provides increased depth performance and slower recovery speeds which are acceptable in minimally mineralized soils when compared to the other modes.

In DISC.1 FAST and DISC.2 DEEP modes, the Au GOLD FINDER will produce a low tone for iron and positive hot rocks. For all other metals, detector will produce a single tone which increases in volume and pitch as the coil approaches the target.

NOTE: Nuggets under hot rocks may generate a low tone (iron tone) and this is totally normal.

RECOMMENDATION: Familiarize yourself with the Au GOLD FINDER audio tones by testing different metal targets and hot rocks prior to use in the field.

RECOMMENDATION: If you dig a target signal and locate and remove a hot rock, rescan hole to ensure there is no small gold nugget remaining.

Nokta AU Gold Finder Settings


Functions as the On/Off and Volume control for the AU Gold Finder.

MODE Toggle Switch

Used to select each of the three search modes.


DISC FILTER is used to eliminate undesirable targets when DISC1. FAST and DISC2. DEEP modes are selected. The default setting for DISC FILTER is ten ‘10’ and is clearly marked on the Control Panel. Adjust DISC FILTER as needed to eliminate unwanted target responses (nails, coins, etc.).

NOTE: DISC FILTER is functional in the DISC.1 and DISC.2 modes only. DISC FILTER is non-functional when ALL METAL mode is selected.

DISC FILTER enables elimination of response to undesirable targets. DISC FILTER provides User with the ability to reject mineralized rocks (hot rocks) and undesirable targets such as iron and foil which often interfere with detector response. DISC FILTER ranges between 0-40. The factory default value (optimal starting point) is ten '10' which is clearly marked on Control Panel.

To use DISC FILTER, first GROUND BALANCE the Au GOLD FINDER. Select one of the Discrimination modes (DISC.1 FAST, DISC.2 DEEP). Next, set the DISC FILTER to '0', then sweep the coil over the undesirable target while simultaneously and slowly turning the DISC FILTER knob clockwise until no response is heard.


It is the depth setting of the device. It is also used to eliminate the ambient electromagnetic signals from the surrounding environment and ground noise.


This setting is used to adjust the humming sound, referred to as the threshold sound, which is continuously heard in the background in the ALL METAL mode. It is used to increase the target signal, in other words, the depth of the device.

iSAT / iMASK Knob

It controls the iSAT setting in the ALL METAL mode and the iMASK in the discrimination modes. Because it is a common knob for 2 different settings, it is recommended that you leave it at the factory recommended level when switching between the ALL METAL mode and discrimination modes and adjust it when necessary.


For the ALL METAL mode to perform accurately, a stable threshold sound is necessary. Changes in mineralization and soil structure may cause a rise or fall in the background hum and disrupt the threshold's stability which will result in losing target signals of certain metals such as small gold nuggets. iSAT feature maintains the steadiness of the threshold by adjusting the speed the device recovers its threshold sound.


It is used to eliminate false signals caused by ground noise or hot rocks when searching in discrimination modes.

TONE and LED Switch

In discrimination modes only, this setting changes the tones the device will produce for targets and it turns the discrimination LEDs on or off. When the switch is at 1-TONE LED ON position, the device will emit the same tone for ALL METALs (gold, non-ferrous, ferrous) and the LEDs will light up according to the type of metal detected. The red led will light up for ferrous and the green LED will light up for gold/non-ferrous metals. Metal alloys or weak signals of very small nuggets may light up both LEDs respectively. Using the device in 1 TONE will enable you to hear smaller gold nugget signals more clearly.

When the switch is at 2 TONE LED OFF position, the device will produce a low tone for iron and positive hot rocks. For gold and non-ferrous metals, it will produce a single tone just like in the ALL METAL mode, which increases in pitch as the coil approaches the target. The discrimination LEDs are inactive at this position and thus will not light up upon target detection.

BOOST Switch

BOOST works in the ALL METAL mode only.

The audio boost switch boosts the sound of weak signals received from small or deep targets making it easier for you to detect those uncertain targets. It is recommended that audio boost should be used on a temporary or as-needed basis because it will not only boost the target signal audio but it will also boost the loudness of ground noise and false signals along with the threshold hum.


This feature tracks the changes in ground and automatically adjusts the ground balance to suit. For more details, please read ''Ground Balance'' carefully.

This is the one I were hoping was going into production when I first heard about it.

Instant thought was 'you beauty, can be mounted on a straight shaft in front of the handgrip .....huge deal breaker for me.

Attention NENAD.... If you read this thread mate, would you know if we will end up with them here, or a purchase from hellyco the only option? Ta...

Pretty much seems to be a gold racer in retro packaging.  Reminds me of the gb 2 days. I dont pay attention to kellyco. is this the first exclusive for them or have other companies done exclusives with them?

So many new VLF gold detectors to look at lately, sure wish they could be rented or seen all at one location to try out first vs

buying one, then dump it to try another and repeat... . Looks like this is the only one of the bunch that can be hip or chest mounted tho? Whats a treasure hunter to do?

What you said...it's crazy how many good detectors have been/are being released currently. :wacko:

I am 98% certain all Gold Racer coils will work on this model, which would mean a concentric option available.

All sorts of companies have done exclusive "made for Kellyco" deals. However, we really do not know all the details on this yet so I would not assume anything at this point. It would not be in Noktas interest to do anything to limit distribution in a way that our hurt sales.

      Here's a video I shot at a friends farm permission in mid Feb 2016 using my Minelab X-Terra 705 metal detector. The day wasn't the best to start with, the minelab x-terra 705 was finding lots of trashy junk items in the field, I detected for over 2 hours with the minelab and nothing but trash was found, but typically just as I was starting to get sick of the trash and thinking of calling it a day, I started heading back to the car when coin after coin started popping out, finding 6 coins in literally the last 30 mins of detecting on the walk back to the car, it saved the day which would have otherwise been wrote off. Goes to show not to stop detecting until you're packing up as you never know what you might swing across.

      Lol. And before someone asks, I do have permission...reason for the nighthunt is the hwy you can hear in the background.

      A short video from a metal detecting trip using my Minelab X-Terra 705 metal detector on some local wasteland. My friends have detected this area over the years but I thought I would give it a go myself, I didn't have the best day finds wise but the Minelab X-Terra 705 did manage to find me my first love token made from an old coin. Because I hadn't heard of such a thing before today, I didn't realise what it was and when I dug it, I tried to bend it back in to normal shape, not realising it had been purposely bent to the shape it was, now I know for next time if I dig a bent coin, not to instantly try ans straighten it, live and learn ehh...
