Garrett ACE 250 fake, how to identify. Photo

Here is the distinction between MD 6250 China fake and Garrett ACE 250 original. Of course, the copy is impressive, but there is a difference after all. Watch the photo.



The coil of MD 6250 China fake isn’t sealed… Its bottom part is closed (glued) with a plastic cover.
The bottom part of Garrett ACE 250 original coil is sealed.


The first problems of the MD 6250 owners have already appeared. First, the coil leaks and causes the continuous false responses.

Second, the coil fails to operate because of a side impact (for example, with a rock or tree). After such an impact the metal detector starts to give a response to any trembling of the coil. No matter whether there is a target under the coil or not – there will always be a response.

  • The reason for this coil impact problem is that the Chinese don’t entirely seal it off, but fasten the turns of wire at a few points (leaving the empty space). This fastening is not enough for a side impact (the original coil can easily withstand it). If the fastening is lost, the metal detector loses a phase and any trembling of the turns inside the coil causes a response.

    In addition, this fastening can’t withstand the temperature. The black coil heats up quickly in the sun and the fastening of coil wire turns also warms up, herewith losing its functionality.

    • I’ve got the Chinese md3010ii and it has found loads very deep, I just made 30 pounds with it today, but the hinge is breaking up, and the coil is hard wfired, so I’m going for the real ace 250, also have a Viking v5 which has been ok

  • These detectors are identical clones created by reverse-engineering the original Garrett circuit and rebuilding it within a slightly revised pcb to cope with more readily available electronics in the chinese manufacture plants. No real alteration of values is made or parts substituted for inferior, the circuit design is sound! And they have cloned the IC data so the behaviour is the same with same tones etc.
    The coil is where the product suffers, It’s a slightly cheaper grade copper and not coiled as strongly, but performance differences seem unnoticeable to the average user.
    Best solution? Pop open the coil plastics and coat some black RTV silicone sealant at various points across the coil windings and re-seal the coil casing. You’ve solved it’s only weakness!
    Also some of the basic wiring solder joints may need a slight improvement although some i have seen have been soldered beautifully, the odd one not so much, still connected fine just ugly and rushed soldering occassionally to the headphone socket etc. 2min solder job to fix.

  • so just silicon sealant coil or/ fit a better coil/ to save money as most electronic parts are /made in china how days anyway .get a bargain while you can/without costing an arm and leg in brand name and advertising charges./save channel on e bay sell these for 93 quid delivered.

    • Hi Mark I have one of these, as good as Ace 250, have added a Nel Tornado coil kickass machine. Got mine on eBay like you said. See my videos here:

      • does the nel tornado coil fit straight on and function properly with the 6250’s standard features or do you have to addapt it with some form of prog?

      • what did the coil cost u?

  • I found this cloned ACE MD2030II unit in a house I just bought.
    Its missing the search head.
    Can a the real ace 250 head work on it?
    And whats the cost of a new search head?
