A question for a cold snowy day...Frequencies

[oldranger]

Its lousy oout so naturally Im thinkin
about and

The GTI has 4 different frequencies
Ive always run witht the factory set one

Is there any advantage to chaging freqs when Im
out hunting .. does one make for better coin
or jewlery hunting etc than another ?
Just wondering

Just off the top of my head (Please correct if I've mispoken):

The newer detectors seem to be doing more no matter the frequency - it's in the electronics and processing. This has been said by a few of todays top MD designers.

The older (recently) detectors seem to follow the old rules -
- Lower frequencies are generally better on high conductors (silver, copper)
- Higher frequencies are generally better on lower conductors (gold, lead) and small / thin targets (hammered coins in Europe)
I think the higher frequencies often do better at ID'ing iron, the lower falses on it easier (from my experience)
- Lower frequencies on more mineralized ground (And seem to do better on very wet ground).
Of course DD coils help alot here too. (Multiple frequencies seem to rule in bad ground and on the beach)

- So, "relic machines" were and are often around 12 - 14kHz.
"coin machines" often 8 - 12 kHz

Something you should be trying is once you find a target, check it in the other frequencies to find what is best for your ground and conditions, cause the above is partly theory. I think you might want to try ground balancing when changing frequencies, to make things equal.

There is soooo much info on the web regarding frequencies, really recommend doing a Google and Bing search (using different engines gives me different info!)

Hope that helped

The 4 frequencies on the AT PRO are so close together that they don't make any practical difference when out detecting. They are just for shifting the frequency of the machine off of a harmonic from some interference or so that 2 AT PROs can work next to each other at the same time by using 2 different frequencies just far enough apart so they won't interfere with each other. Samething applies if you are using some other brand that runs at 15 Khz too.

Steve what about the GTI1500?

 

[earthmansurfer]

Oops, I thought you meant in general, not just offsetting.

Anyway with that said, I now always switch from my detectors default frequency and it really improves on the chatter, without other detectors nearby. It works surprisingly good.

Only thing they're for is interference. They change nothing else.

I have a 1500, you change it when you are hunting close to another machine, it good for club hunts
