Reasons to use a Small Coil

May 24, 2010 10:51am

Small coils have extremely good depth and sensitivity despite what popular belief would tell you. If you regularly search areas that you know contain valuable old coins and lots of iron and rubbish then you owe it to yourself to get a small coil.

Why should I do that? The reason is simple really...

Counterfeit Minelab Metal Detectors

May 17, 2010 09:30am

Imitation is said to be the greatest form of flattery. However, counterfeit Minelab gold prospecting metal detectors and accessories that don’t work is another story altogether.

Counterfeit Minelab metal detectors and accessories are entering the market which either don’t work at all or have extremely poor performance. Unsuspecting detectorists are being tricked into buying metal detectors that look like a GPX-4500, but at best perform like a $50 toy detector.

We first heard reports of counterfeit GPX-4500 metal detectors late last year and obtained a confiscated counterfeit GPX-4500 from Dubai’s Customs Department. We disassembled it and...

GPX-4500 - Why so many Timings?

May 10, 2010 08:55am

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...

Minelab E-TRAC Audio Tones

May 04, 2010 10:21am

Hi, my name is Philip and I work in R&D at Minelab in Adelaide, Australia. This means that I have probably helped to test or implement some of the features in the metal detector that you are currently using. I’m sure that you love, hate or are completely indifferent to these. In this forum I would like to talk about some of my experiences in creating these features or my perspective on the feedback that I hear from customers. This is my chance to talk with the world of metal detecting rather than those few that I get to meet personally. Please join in and leave a topical comment or ask a question.

My first topic will be on the E-TRAC audio for new users...
