running two detectors

Help Support Prospecting Australia:
The spacing to avoid interfering with each other depends on the detectors. For the Minelab GPX units, its 20m to 30m minimum with a mono coil.
I understand that the GPZ and SDC are less susceptible to interference from the GPXes, but the GPZ and SDCs create havoc with the GPX, and again require 20m to 30m separation. Happy to be contradicted though.

GPX and SDC are a great combination, but SDC and GPZ is better (but way more pricey) IMHO.
Depends on the detector. Some have the ability to shift frequency slightly to avoid this issue. I guess it depends on how close you are.

SDC / 4500 was my choice combo to cover all bases great value for money current deals , also enjoy using one for half day then changing up as you have to listen for different things which keeps you fresh mentally.
Good luck which ever way you go

You sound like a very accommodating mate :Y:
Funny you ask this question as I was watching a vid of a kiwi fella testing a GB2 and a Gold Monster right next to each other and I asked how this was so.
Well apparently VLF and PI play well together. He runs his GPZ and GB2 right next to each other when he uses the GB2 to check a deep target or clean out a hole.
So maybe a GPX or GPZ matched with a Gold Monster might be better?

Me and a mate were using 2 MXT's running the 12"/300mm Concentric Coils and I could hear him heading my way within about 100 metres or more, It started with a soft pulsing sound and by time he was within about 30 metres it was right on the limit, within 10 to 20 metres it was totally impossible and time to pack up,
It was funny at first but then one of us had to change machines or go home,

Well that's curious RR. Were they both at the same kHz? Maybe VLF and VLF play well if they are different kHz? MG is 45 and GB2 is 71 or something.
Not a tech head though - just guessing

The MXT's run at 13.889 kHz ( 14 kHz ), I was running mine at the point of running rough and I just backed it off to smooth it out and my mate was running his around the pre set mark which is about 9.5 on the Dial so mine was running at about 10.5. But those big Concentric coils do have some serious power and they are a lot more sensitive than a DD.
The detection field is extremely strong but the machines them selves are Hyper sensitive when you run them up around the pre set position and above, where they can see your Bare hand/ skin at about 6 inches away +/- Using the standard 10"DD, So I think that is why they behaved like they do and those 12"/300 Coils are really pushing it, And on the beach you can't max the Gain right out but because of those Coils you don't need to, I have seen coins come out at 13 and a half inches with the Gain set to 6.5 on a ploughed field So cross talk between the two machines was to be expected really,
hope that helps.

We've been running the GPX4500, SDC2300 and Whites GMT for a couple of years. The SDC and GPX send each other little pulses but at varying distances depending on the day. Some days I can sneak up to about 10m before I here a grumble from the SDC swinger. Other days 50m seems to be the limit so I think it has something to do with the conductivity of the air on the day.
If the SDC comes too close GPX I don't grumble, I just alter the main tune frequency slightly and tune it out. The GMT can play along very close down to as little as three metres to either PI without any problems.
