A metal detector lets you search beaches, parks and fields for coins and relics. We have not used these products ourselves, so this guide does not rank anything. It shows you how to compare coils, modes and weight before you choose a detector.
Think about where you plan to search. Dry parkland, wet sand and shallow water each call for different features. Next, think about how long you will carry the machine, since a heavy detector can tire your arm during a long outing. Beginners often like simple controls and preset modes, while experienced users may want manual tuning. Check the local rules for the places you want to search, and ask permission on private land. Plan your first few outings near home so you can learn the audio tones before travelling further. Having a clear idea of your search sites and your patience for settings will make the table below far easier to use.

What to Look For
| Factor | Why it matters | What to check |
|---|---|---|
| Coil size | Larger coils cover more ground, while smaller coils handle clutter better. | Read the coil description and whether other coils fit the machine. |
| Search modes | Preset modes help beginners, and manual control suits experts. | Look at the list of modes and any ground balance option. |
| Discrimination | It lets you ignore some junk metals while you search. | Check how the display or tones show the type of target. |
| Weight and balance | A lighter, balanced machine is easier to swing for longer. | Look at the stated weight and the adjustable shaft and arm rest. |
| Water resistance | Beach users may want a coil that can go in shallow water. | Read exactly which parts the maker says are waterproof. |
| Headphones and display | Clear audio and a readable screen help in bright or noisy places. | Check for a headphone jack, wireless audio and a backlight. |
Setup and Care Tips
- Adjust the shaft length so your arm hangs naturally and the coil sweeps close to the ground.
- Practise on known targets in your garden to learn how each tone sounds.
- Rinse the coil with fresh water after any use near salt water, then dry the machine.
- Remove batteries before long storage to avoid leaks inside the housing.
- Carry a small digging tool and fill every hole you make before leaving a site.
Mistakes to Avoid
- Buying the most complex machine when simple controls would suit a beginner better.
- Searching without checking local rules or the landowner’s permission.
- Ignoring the weight of the machine until your arm tires on the first outing.
- Using a machine near water when only the coil is made for it.
- Setting discrimination too high, which can hide valuable targets along with junk.
FAQ
Which coil size is best for a beginner?
A medium coil is a common choice because it balances depth and ground coverage. Check what the maker supplies and whether you can swap coils later.
Can I use a detector on the beach?
Many models are used on beaches, but wet salt sand can affect performance. Look for ground balance features and read what the maker says about water resistance.
The Short Version
Decide where you will search, choose a weight you can carry, and match the controls to your skill. Then check the coil and water resistance before you commit.
