Modern Detectors - UK Test Garden Results #2

Some folks may be interested in other work done by Staffordshire Metal Detectors in the UK, which I have placed in chart format. These are test-bed results for many detectors and coil combinations on targets that include nails oriented in various ways to make identifying the non-ferrous target challenging. I put the codes for each of the 17 target arrangements (e.g., D1, D2, D3, etc.) with an explanation of each test setup in this thread. There are 10 charts showing the results of his testing below. Each colored block has the code (example G1) for that particular test (check the legend to understand what the test is measuring). Here's how it works: If a test target is detected, it gets a colored block on the positive (blue) side (above the red zero line). If a target cannot be reasonably identified in the ground, its colored block goes in the negative detection (red) side (below the red zero line). If all test garden targets were detected, then all 17 colored target blocks would be above the red line as positive hits. The charts are ordered with the highest-scoring detector/coil combinations first, with scores decreasing to the lowest scoring detectors on chart 10.

The blue line and values (coded P1) are his overall rating of each detector/coil combination based on its performance in the test-bed (the highest score possible is normalized to 17). At the bottom of each chart is the graphed depth performance of each detector/coil combination on targets H1, H2, and H3. The green, orange, purple graph values are the maximum depth obtainable on each in-ground target. If the graph dips down to zero (read on the scale on the right side), it means the detector/coil combination did not hit on the target. For instance, if the H2 orange line has "H2=11in," it means the maximum depth on that target was 11 inches in the ground. There was originally an S1 trace (mentioned on a legend), but I removed it as it caused too much clutter.

Note: all the detectors were set to stable operation and set to reject nails, small iron, and coke, if possible. An unstable, sparky detector might gain more depth, but a more reserved/normal-use setting was chosen instead. Most of the targets have been buried in his test garden for at least 15 years. Again, you can visit his site for more information (Staffs) or read his blog on his UK adventures. This is for informational purposes as results may differ with your soil and settings. Enjoy!
