Nokta AU Gold Finder Metal Detector
with 10x5.5" and 5" Waterproof DD Search Coils, Headphones, Coil Covers and a Hip Mount Belt. *Ships World-Wide*
Going for the gold has never been easier than with the Nokta AU Gold Finder Metal Detector! This deep seeking gold machine was built to find large and small nuggets in any terrain. The AU Gold Finder utilizes automatic, tracking and manual ground balancing for maximum cancelization of highly mineralized soil. Operating at a 56kHz frequency, this device provides the ultimate in sensitivity and depth when hunting for gold.
The AU Gold Finder features three distinct search modes for a better gold hunting experience. The ALL METAL Mode penetrates the farthest into the ground and is great for finding just about anything. The DISC.1 FAST Mode was programmed for gold hunting in fields with high mineralization or significant quantities of conductive rocks. This mode improves target detection and recovery speeds in areas where there is a lot of trash. The DISC.2 DEEP Mode gives the user a two tone discrimination setting designed for gold fields with less mineralization or hot rocks. It provides an increase in depth performance while still being able to pinpoint large and small gold nuggets.
The AU Gold Finder features easy-to-use switches and knobs to take the guess work out of operating the device. It even comes with IP54 Rating which protects the metal detector from any dust or water spray. To top it all off, the device includes two waterproof DD search coils (one 10x5.5" and one 5") and two search coil covers for the ultimate protection.

ALL METAL Mode
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 Mode
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 Mode
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. If you dig a target signal and locate and remove a hot rock, re-scan hole to ensure there is no small gold nugget remaining.
OFF / VOLUME Knob
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.
SENSITIVITY directly affects the detecting performance (depth) of the Au GOLD FINDER. SENSITIVITY range is '1-10'. Default SENSITIVITY is seven '7' which is clearly marked on the Control Panel and should be adjusted according to environmental and ground conditions.
Minor adjustments to SENSITIVITY may also be effective in eliminating or reducing detector instability due to electromagnetic signals and high ground mineralization.
NOTE: Decreasing SENSITIVITY will often resolve coil overloading due to highly mineralized ground.
THRESHOLD switch is used to adjust the background hum sound commonly referred to as the threshold sound. THRESHOLD tone is continuously heard when Au GOLD FINDER is operating in the ALL METAL mode.
iSAT / iMASK Dial
iSAT / iMASK switch is a multi-function switch controlling iSAT settings when ALL METAL mode is selected, and alternately controlling iMASK settings when DISC.1 FAST or DISC.2 DEEP are selected. Default position for both iSAT and iMASK are calibrated at six '6' and are clearly marked on the Control Panel.
Optimal performance using ALL METAL mode requires a stable THRESHOLD. Changes in ground mineralization and soil structure may cause a rise or fall in the background hum. A disruption of THRESHOLD stability may result in loss of target response to certain metals such as small gold nuggets. You should only adjust iSAT to maintain the steadiness of the THRESHOLD tone. Adjustment directly affects the detector recovery speed and THRESHOLD stability.
iSAT consists of ten levels. The default level is six '6' and is clearly marked on the Control Panel. It is recommended that iSAT be increased when detector is used in high mineralization and decreased in low mineralization.
iMASK is used to eliminate falsing (false signals) caused by ground mineralization or hot rocks when searching in discrimination modes. Default iMASK setting is six '6'. At level one '1', iMASK is turned off.
TONE / LED Toggle Switch
The TONE / LED toggle switch provides the User the ability to choose between audio/visual (single tone/LED) response and audio (multi-tone) response as follows:
-1 TONE LED ON provides User with single tone target response and simultaneous LED display of FERROUS (Red LED) or GOLD NON-FERROUS (Green LED) target identification.
NOTE: Using the Au GOLD FINDER in 1 TONE will enable you to hear smaller gold nugget signals more clearly.
-2 TONE LED OFF provides User with two tone target response. Low tone for iron (ferrous) or hot rocks and a higher tone similar to ALL METAL target response which indicates gold and non-ferrous metal targets.
NOTE: The discrimination LEDs are inactive in this position and will not light up with target identification.
BOOST amplifies the weak detection response for very small or very deep targets increasing the detection probability for even the most difficult targets. BOOST should be only be used on a temporary or as-needed basis in highly mineralized ground because it will amplify threshold hum, ground noise and may contribute to increased detector falsing.
NOTE: BOOST works in ALL METAL mode only.
Use of TRACKING automatically adjusts GROUND BALANCE to compensate for changes in ground mineralization while detecting.

I found a nugget using the AU in less than 20 minutes. It weighs 1.5gm. I got $45, so yes they find gold and are good (Nokta). Its only that in Zimbabwe they know Minelab and they trust their products and use X-Terra 705 and GPX 5000 but I believe that a lot of people are now getting to see the importance of these Turkish detectors, I like the Nokta very much. I have found gold with it where I used to go with my Garret ATX and GPX 5000 (friend). They also use the AT Pro but it is not popular.
I also found a 5 cent bond coin and that area had a lot of trash. If it wasn't for the AU's visual discrimination I would not have found it.
I found 6 nuggets in 3 days with the AU when I went to the bush in about maybe 6 hours of detecting. They gave me $138 x 14.5 =R2000.
If I would have sold it direct to the bank I was going to get about around R2.600.
An Answer to the Often Asked Question
Review by Kevin Hoagland on July 19, 2016
Over the years I have used every VLF detector built for gold, and that is not an understatement, it is what I do.
Nokta did it right, they listened to the Detectorist and built into one detector what we have been looking for. High Frequency response with the ability for hitting small (sub gram) gold nuggets, auto and manual ground balance, precise sensitivity adjustment capabilities, reliable and clear threshold and the sheer ability to handle iron ground minerals were the requirement. The fact that the Gold Finder is lightweight, hip-mountable, has long battery life and a decent price tag, well that’s just more gold in the poke.
The Gold Finder is not just another HiFreq VLF coming into a fairly crowded market space. It was designed by engineers listening to the Detectorist and they never stopped asking questions until they were assured that they had built the best machine they could, and I like it.
The Gold Finder is easy to use and was intuitive for me right out of the box. A new user will find it has a short learning curve and is well worth the time. Experienced Detectorists will immediately recognize the detector's ability to handle some of the worst iron soils without having to de-tune the detector to the point of loss of targets while still having a great rhythmic threshold. If it shutters, you better dig it.
Bottom line, I use it, I find gold with it and I am not planning on giving it up as a VLF detector in the tool bag anytime soon.
My Go To VLF Detector
Review by RayMills on March 24, 2016
Nokta continues to offer new and innovative detectors for Gold Prospecting. The new AU Gold Finder is the latest and I think one of the "best" VLF Gold Detectors to be released recently. The AU Gold Finder is an all manual unit that allows the user to manually adjust all settings. This may sound like a throwback for newer detectors, however, the ability to manually adjust a detector that is dedicated for gold hunting is simply fantastic. I love this "throwback" tremendously. This unit runs extremely smooth in the hot ground I detect on. It detects gold from sub-grain, not grams, to larger nuggets and gives a very nice signal response to both in any ground. I am very impressed with the stability in all three modes and even found one small nugget the first day out, actually, the first hour out. This is now my "go to" VLF detector. Thanks, TRINITYAU/RAYMILLS
