Eric.....best setting for the big gold rings ??

[Tony]

Eric....this question is for when you get back from your holidays so I'm not expecting an answer right away !!!

If I'm after the bigger/heavier gold and platinum rings (typically 18ct for the gold), will a slower pulse delay help me find them deeper? Normally I will set up my Goldquest at 10uS if possible when hunting the wet sand and definitely at that setting on the dry sand. I was thinking that settings at around 20uS+ might find them deeper, the other half of my brain is telling me to leave the delay at 10uS (where conditions permit).

My logic behind this is the decay rate of higher gold alloys don't need quite so fast pulse delay to "capture" them....this is obviously not the case for the finer gold rings.

Am I way off target here....it won't come as a surprise.....

Regards,
Tony.

Hi Tony,

With the Goldquest SS, there is some benefit to turning the Pulse Delay to a longer setting, when looking for bigger, or more conductive items. The primary reason is that at the longer delay settings, the transmitter pulse is also longer. At 10uS delay the TX pulse is only 30uS wide, which is OK for thinner or less conductive rings, but is a bit too short to generate the best signal in bigger things. Whatever the pulse delay is, the TX pulse is 3 x as long, so a 30uS delay will result in a 90uS TX pulse which should be better. You will also benefit from considerably less signal from the wet sand.

Just had a phone call from my most recent GQ SS customer in the UK. He has found 11 rings in just four days of searching about two hours per day. He will be posting his story shortly.

Eric.

Eric,

As always, thanks for the detailed response.

At least I was on the right track to some degree.

I might do some tests on big gold rings.....see how different delay settings relate to a deeply buried ring.

Regards,
Tony.
