Comparing the 15 kHz & 30 kHz on gold. Why is high frequency necessary?

The so called “not diggable” signal can be given by anything – by both a rusty nail and a gold coin, everything depends on your machine and your experience. Below is a case in point, let’s take a look at a comparative test between two metal detectors: the DeepTech Vista Smart Plus operating at 15 kHz vs the DeepTech Vista Gold Gain working on 30 kHz. The test is being conducted in highly mineralized soil. Test target: a gold coin. Here you will find the answer to the why-does-a-detector-need-a-high-frequency question. Notice how the unit running at 15 kHz is detecting the coin. How often do you hear such signals while hunting? It’s the real classic of not diggable audio response! Continue reading

Minelab WM-08 Teardown + signal problem solution

Sometimes users impose inefficiency – because of the sound latency – as a charge upon the Minelab WM-08 wireless module. First, have you seen the electronics inside? The WM-08 circuitry is more complicated than that of the XP Deus. Second, the problem lies not in latency but in signal loss (that is mistakenly taken for the delay). Third, read the manual. Here below are the pictures of disassembling the Minelab WM-08 wireless module. Plus, what problems can occur and how to solve them. Continue reading

Opening the XP WSA wireless headphones (for XP ORX)

Why did French manufacturer XP register the trademark XP WSA® for its new headphones? While it’s a mere headset, wireless though and/or using a new technology, as the manufacturer himself states. So let’s take a look at what’s inside the ones XP is taking care of too much. Here’s a pictorial review of disassembling the XP WSA wireless headphones for the XP ORX machine. I don’t think XP will be pleased to see such pictures but maybe they will come in useful for someone who’ll decide to repair his headset himself. By the way, this is the first time I see the white circuit boards that are used by the md manufacturer. Continue reading
