GPX-4500 - Why so many Timings?

10 May 2010

To an answer the question above, one needs to know what the Timings actually do. In simple terms, the Timings control the internal parameters of the metal detector’s electronics, or more precisely, the pattern of the pulses. This pattern defines the metal detector’s performance characteristics. So why not just make a single Timings setting that is good for all scenarios?? Well, yes this is possible, but it would have to be a compromise.

Think of a car transmission, 1st gear is great for a steep hill climb, but you wouldn’t use it on the open highway. Likewise, 4th gear is great for the open highway, but you wouldn’t use it to take off! Timings are the same – each Timing is good at a specific task. The Timings have a bearing on depth, sensitivity to small targets, immunity to EMI, and the way they deal with mineralisation. The following chart rates the ability of each Timing option:

So which Timing should you select to work an area? One scenario might be: you are targeting deeper ground so need good depth, the ground is only mildly mineralized, and you are unlikely to encounter any EMI. By looking at the chart, simply find the Timing that best fits these characteristics. I would say Sharp and Normal seem to fit best.

If the ground is only mildly mineralized, Enhance timing isn’t needed, but if you want to use a Mono coil, Sharp is probably going to be a bit too powerful, so Normal is the best option. In a different scenario, let’s say you want to detect some shallow ground that is more mineralized, and want to use an 11” Mono. The Timing will need to provide good sensitivity, good ground handling ability, and should work well with Mono coils. The easy winner here is Enhance.

Having six different Timings options at your disposal gives you more control over the performance of your metal detector than ever before, so try them all out, experiment with the Timings in different locations, and see how they can work for you!

Hi, I bought GPX-4500 2 days ago, in order to detect large and huge tresures (hand-made gold). Having read the user's manual I am bit confuesed in how to setup this GPX-4500 in a good way . Please help .

Thanks

The Deep Search Mode is optimised for deeper targets, so use the factory settings as a starting point. The best timing for large/deep objects is Sharp, but its use is restricted to areas of low mineralisation. In medium/average mineralised soil, Normal timing is the preferred option.
