There are 3 main types of metal detectors;
VLF (very low frequency) – most versatile, two coils, one
sender, one receiver,
PI (pulse induction) – like radar, works best when there’s little amounts of rubbish (e.g. bottle caps, tin cans etc),
and BFO (beat frequency oscillator) – the oldest type and not often used anymore as it lacks accuracy or control, but has two oscillators (one of which is de-tuned by metal objects).
If you are serious about taking up metal detecting as a hobby then be prepared to pay a minimum of £200 for a decent detector (any less and you’re just getting a non-functional toy, anymore than £500 and you’re getting ripped off).
Here are some good quality brands that cater to a limited budget:
