Tin Cans: The Unsung Heroes of Metal Detecting

Tin cans, the unsung heroes of metal detecting. These little cylinders have been around for over 200 years and have served many purposes. From preserving food to being used as makeshift ashtrays, tin cans have played an important role in our lives.

But what about their role in metal detecting? Well, let’s just say that without tin cans, many a detectorist would be going home empty-handed.

First off, let’s talk about how tin cans are made. Tinplate is a thin sheet of steel coated with tin. This coating makes the can resistant to corrosion and allows it to hold acidic foods such as tomatoes without reacting with the metal.

Now, when you bury a tin can in the ground, it becomes a perfect target for metal detectors. The steel core of the can will produce a strong signal that is easily detected by even entry-level machines.

But why are these signals so important? Well, they tell us where to dig! When you’re out on a hunt looking for treasures or artifacts, you want to know where your target is exactly located under the soil. Tin cans provide clear signals that allow detectorists to pinpoint their targets and recover them quickly.

But there’s more! Tin cans also serve as excellent decoys for other metals like gold and silver. When precious metals oxidize underground they emit an electrical charge which can mask them from detection. However, if another metallic object is buried nearby (like our trusty tin can), it will draw attention away from those valuable finds and give detectorists false positives instead.

Now I know what you’re thinking: “but aren’t tin cans litter?” It’s true that these little guys do contribute to waste but hear me out – there are ways we can help reduce this impact while still enjoying all their benefits.

One way is by recycling! In most places around the world now days we have access too recycling centers where all types of metals including tins cans can be easily disposed of in a proper way for reuse. Another way is to pick up any cans that we come across while out detecting and disposing of them properly ourselves.

In conclusion, tin cans may not be the most glamorous object found while metal detecting, but they are certainly one of the most useful. Without these little cylinders, detectorists would have a much harder time locating their targets and separating them from other metals in the ground. So next time you’re out on a hunt and you hear that familiar beep-beep-beep coming from your machine, remember to thank all those unsung heroes buried beneath the soil – our trusty tin cans!
