Metal detecting with children in the UK

Start with the right place

A garden you control can be useful for simple surface tests, provided you know what is buried there. For a real outing, get the authorised landowner or occupier's permission for both detecting and any digging. Do not assume a public park, footpath or open beach is automatically available. The UK permissions guide explains why land access, detecting and recovery are separate questions. Avoid scheduled sites, livestock, crops, steep banks, littered ground and places where a child could wander beyond your agreed area.

Tell the child what a detector does and does not do: it responds to metal, not to “treasure”. Begin with a few familiar safe objects placed on a mat or on the surface of permitted ground, then move to ordinary signals. Set a small search patch and an easy finish point. A 20-minute successful session is better than hours of tired swinging and holes. Bring water, suitable layers, hand wipes, gloves and a way to collect ordinary rubbish.

Fit matters more than the age printed on the box

The child should be able to hold the detector with a relaxed arm and move the coil low over the ground without dragging it. If the shaft remains too long or the coil feels heavy after a few minutes, the machine is not a good fit however attractive its screen looks. Nokta describes the Midi Hoard as an 880 g, 83–109 cm adjustable detector for roughly ages 8–12+; that is a manufacturer's guide, not a universal size rule. An older or taller child may be more comfortable with a simple adult machine. See our children's detector guide and teenager guide for those different needs.

Teach the sequence, then supervise recovery

Demonstrate a slow overlapping sweep, a second pass from another direction, and how to stop the coil without hitting a person or animal. Praise a careful check even when the target is a bottle cap. A number on the screen cannot identify an object with certainty; the first signals guide explains what the audio and repeatability can tell you.

An adult should decide whether recovery is permitted, safe and sensible. Check for glass, sharp scrap and unknown objects before a child reaches into soil or sand. Keep the recovery tool in adult hands unless the child is old enough, trained and directly supervised for that particular tool and ground. Restore any authorised plug neatly and remove safe litter. Never let a child pick up suspected ammunition, an unexplained container or a possible hazardous find; stop and follow our dangerous-finds guidance.

If a potentially archaeological object appears, photograph and record the exact private findspot before moving it. Do not scrub it to make the pattern visible. The finds-care starting point shows a simple record. Be clear with the child that ownership and reporting do not change because they found it; the finds ownership guide covers that conversation.

Finish with a small win

Let the child choose one ordinary safe object to sketch or photograph, and note which sound led to it. Count recovered rubbish as useful ground care. Check clothing for ticks after grassy or scrubby ground and follow NHS advice if one is attached. At home, clean hands before eating and compare the day's signals with the beginner practice plan. A good first trip ends with curiosity intact.
