minelab coil pinouts

[greybeard]

I'm chasing info on the pinouts and connector used for minelab coils.
Specifically the later GP models.
I'm currently playing with a couple of hammerhead projects and i'd like to utilise the same connector and pinouts to ease experimentation with homemade and commercial coils.
thanks

Greybeard, often Minelab puts an amplifier inside search coil housing. This is RX preamp, powered by voltage across TX coil.

Hi GB,
The SD and GP are the same pin outs they are as follows
DD coil. Mono Coil.
Pin 1 = RX Shield and link to pin 5. Pin 1 = Shield and link to pin 5.
Pin 2 = RX Center. Pin 4 = Center and links to 2/3.
Pin 4 = TX Center and link to pin 3.
Pin 5 + TX Shield and link to pin 1.
Hope that helps.
Regards, Ian.

Yep they are the ones.

No pre-amps in the coil either.

Hi GB,
I will try again without the two columns.
DD Coil.
Pin 1 = RX Shield with link to pin 5.
Pin 2 = RX center.
Pin 4 = TX Center and link to pin 3.
Pin 5 = TX Shield with link to pin 1.
Mono Coil.
Pin 1 = Shield and link to pin 5
Pin 4 = Center and links to pins 3 and 2.
Links should be tinned 1.0 mm copper wire Minelab use gold plated Microphone plugs I buy mine from Aztronics in Adelaide but I have to buy 10 at a time also Woody will sell you one off.
