Digging with your hands is out of the question unless you’re on a beach above the wave-breaking line where the sand is soft enough. You’ll also need a trowel, small spade or specialised detector digging tool that can penetrate compact earth without making too big a hole. It’s a good idea to take a spare set with you because detecting can be a very time-consuming pursuit and you don’t want to run out of juice just before possibly striking gold. Most metal detectors run on four AA batteries. Anything else I should consider taking with me? The most tech-laden models can even stream full-colour underground images of the target to your tablet. These prohibitively expensive probes cost as much as £8,000 but they can detect gold up to and occasionally beyond a depth of five metres if the target is large enough. If money really is no object and you have dreams of possibly striking gold, consider a specialised gold detector. However, there are a few models on the market – like the Makro Multi Kruzer, reviewed here – that are configured for use below the waterline. Yes, their coils may be waterproof, but their electronics could easily be confused by the salty water and large amounts of natural black iron deposits in the sand. Most mid-priced detectors will spot something of interest up to a foot deep – and possibly deeper if the target’s a big one.įew budget and mid-priced detectors are suitable for searching beaches below the water-line. If you have a bit more to spend (between £250 and £400), consider buying a model equipped with a wider level of discrimination and a pinpointing feature, which emits a long tone that increases in intensity the nearer you are to the target. This will help it tell the difference between a rusty iron nail and a silver ring or coin, and save you a great deal of unnecessary digging in the process.īest torch 2023: Our pick of the best rechargeable LED flashlights and high-powered torches However, they will inevitably find more trash than treasure so try and go for a model that’s equipped with a discrimination function. Most beginner models start at around £100 and are capable of locating metal up to six or so inches below the surface. Metal detectors fall into a few different categories based on their price. Metal detectors can locate most types of metal, including iron, nickel, copper, brass, aluminium, tin, lead, bronze, silver and gold. When you sweep the detector from side to side – with the circular coil section just brushing the surface of the ground – the magnetic field causes an electrical current to flow through any metal object in the vicinity, and it alerts you to the fact with a series of beeps that get stronger the nearer you are to the target.
