Metal Detector Modification For Garrett ACE 150 250 350 to Display the Audio Tones onto an LED Display
(Metal Detector not included)
This LED display module will display the audio tones from the metal detector graphically onto an LED panel. Each tone and combination of tones is displayed onto the multicoloured LED display in real time as you detect.
This LED display module is water resistant and can be used with both headphones and the normal detector’s display panel to aid in identification.
To use both headphones and the LED display module you will need the supplied stereo splitter to two 3.5mm sockets. One socket is used for the headphones and the other to connect to the LED display module.
This addition to a detector therefore does not invalidate any manufacturers warranty. See Picture 2 of all that is included.
The LED display module is comprised of 64 LEDs and measures approximately 10x7x5cm weighing around 200g. The LED display module has a 3.5mm audio socket to connect to the detector via the 3.5mm audio cable supplied and a micro USB socket for charging the internal battery with the cable provided. Charging takes approximately 5 to 6 hours.
Below is link to the actual LED display module displaying the spectrum obtained when the audio frequencies of the normal human hearing range are played through it:
This illustrates that the LED display module has the potential to differentiate between different metal detector audio tones.
The following video link demonstrates the LED spectrum generated for Gold, Silver and Steel along with the sound tones from a Garrett Ace 250. There are two (2) repeats for each metal in turn:
As well as complimenting the audio and standard detectors LCD display panel this additional LED display module would also benefit the deaf or the hearing impaired.
The following video link demonstrates how to attach the LED module to a metal detector with the supplied fittings:
This LED display module adds another dimension to metal detecting and with time the detectorist may be able to interpret the LED spectrum displayed to aid in identification.
The model available is the RED YELLOW GREEN BLUE version as in the third picture.
(Not RGB as in the video below but they function the same only with a slightly diffferent pattern of LEDs)
To assist with securing the LED module, included is a reusable velcro type strap fastener and self adhesive velcro strips.
These are homemade from quality internationally sourced components
These are VERY water resistant and I have submerged in water without leaks but this is not guaranteed
To maintain optimal settings it is important not to allow the internal battery to completely discharge.
Please charge weekly if not being used.
There is no "Off Switch" on this device and it will occasionally flash when charging.
In the unlikely event that this flashes when detector is not on or there is no audio lead connected please change settings to Low Sensitivity following the instructions below:
Remove the four screws and carefully lift cover by a couple of centimeters only to prevent damaging connected cables.
On the underside of the right side is a function button which can be used to reset the flash rate and sensitivity.
Press the function key for 1 second to change between three display modes:
F: quick flash rate
S2: medium flash rate
S1: slow flash rate
Press the function key for 2 seconds to change between three sensitivity modes:
L: Low sensitivity
M: Medium sensitivity
H: High sensitivity
Carefully re-assemble after reset and do not over tighten screws
