Another Minelab Question, please

[Ken~Digs]

Another question, please. From what I understand the Timings feature Started onGPX (4000) & if not , which model or when ? to what Advantage is this Timing feature and when is it used to do what ?

Is it like a Freq. adjust ? Thanks - Ken

Hello Ken,

Well, there are actually different timings on the GP Extreme and up. On the GP Extreme, there are Sensitive, Normal and Enhance. All three of these are actually different timings allowing the detector to do different things (sensitivity, mineral immunity and more depth). In General terms, the Sensitive timings gives you better depth on smaller nuggets and better detection overall on small gold. The Normal timing is best for outright depth on low to mid mineralization. The Enhance timing is best used where there is high mineralization, such as ironstones, volcanics and hot ground conditions.

The GPX 4000 was the first detector to have more timings than prior GP series. The GPX 5000 has 8 timings, the most out of any Minelab or other Pulse Induction metal detector on the market.

Here is some information on timings I pulled from the Minelab website -

Timings refer to the digital switching rates that control the internal electronics of the detector. In the GPX series of detectors the timings generate a pulse train to create the transmit waveform. The same timings generate synchronised switching signals to control the receive electronics.

Selecting different timings and thus changing both the transmit waveform and synchronised receive switching signals have benefits for different ground types and targets. Minelab has created a range of different timings in the GPX series of detectors that achieve optimum depth, sensitivity and ground balancing across different detecting conditions. (Also see “Multi period sensing (MPS)”, “Dual Voltage Technology (DVT)” & “SETA”)

Hope this helps a bit,

Rob Allison

Thanks Rob , I'll have to find more gold or see how the vehicles turn out when we straighten out what we're doin' with them. Ken

Hey Ken,

Sounds good. If you have questions, don't hesitate to call, email or post it here on the forums.

Talk with you later,

Rob Allison
