Best underwater metal detectors for shallow water: three verified picks.
A waterproof coil is not enough. These three complete detectors can go underwater to the manufacturer’s 16-foot limit, and every Amazon button shown was matched to the exact model.

The quick answer
Pick by water—not by the biggest promise.
All three are fully submersible to 5 meters. The real differences are saltwater stability, controls, audio, coil size, and price level.

Read the water line
Waterproof must cover the whole detector.
A waterproof search coil cannot protect a dry-only control box. The three picks below keep the full detector inside one stated limit.

What each pick solves—and what it does not.
Every detail card uses the official model page. When an orange button is shown, it uses an exact checked Amazon listing and the Detecting Atlas tracking ID.
01
Best budget pick
Nokta SIMPLEX LITE
A light, simple detector that can enter the water as one complete unit.
Why it made the list
The full detector is submersible, it weighs 2.6 pounds, and four simple modes cover common first-hunt ground.
What to watch
It is fully waterproof, but single frequency can need more sensitivity control on noisy wet salt sand.

02
Best value for salt water
Nokta DOUBLE SCORE
Full waterproofing plus simultaneous multi-frequency without a crowded menu.
Why it made the list
It combines full IP68 waterproofing, simultaneous multi-frequency, Beach mode, ground balance, and a light 2.6-pound build.
What to watch
For audio below the surface, add compatible wired waterproof headphones. Bluetooth does not travel usefully through water.

03
Best premium all-rounder
Minelab EQUINOX 700
More target detail and control for frequent fresh- and saltwater hunters.
Why it made the list
Multi-IQ, two Beach profiles, 119 target segments, full 16-foot waterproofing, and a 2.8-pound build give it the widest useful range here.
What to watch
The included ML85 headphones are not waterproof. Full submersion needs the separate wired waterproof EQUINOX headphones.

Ground still matters
Fresh water and salt water are different jobs.
Start stable and shallow.
Fresh water usually adds less salt noise. Check mud, rocks, weeds, visibility, current, and the lakebed owner before entering.
Learn the first underwater huntWaterproof is only step one.
Salt is conductive. Use Beach mode, make the detector quiet, and treat surf, tides, and rip currents as separate safety checks.
Set up for wet salt groundFive-minute decision
Check these before checkout.
Buy for the water you can legally and safely enter—not for the deepest number on the page.
- 1Is the whole detector submersible?
Read the control box limit, not only the coil label.
- 2Fresh water or salt water?
Regular wet-salt use makes stable Beach modes and multi-frequency more valuable.
- 3How will you hear below the surface?
Choose wired waterproof headphones or a useful vibration alert.
- 4Can you control the coil in moving water?
A larger coil catches more water and can tire your arm faster.
- 5What do the local rules allow?
Detector use, recovery tools, water, and the ground under the water can have separate answers.
Buyer FAQ
Simple answers before the water.
What is the best underwater metal detector for a beginner?
The Nokta SIMPLEX LITE is the simplest budget starting point here. Choose the DOUBLE SCORE if wet salt sand will be a regular hunting ground and you want simultaneous multi-frequency.
Does waterproof mean fully submersible?
No. A detector may have only a waterproof coil. Every pick on this page has a complete control unit officially rated IP68 to 16 feet or 5 meters.
Can an underwater metal detector work in salt water?
Yes, but waterproofing and salt stability are different. Wet salty sand can create extra signals. Simultaneous multi-frequency and a proper Beach mode usually make the detector easier to calm.
How deep can these underwater metal detectors go?
The manufacturers rate all three complete detectors to 16 feet or 5 meters. That is an equipment limit, not a safe target depth. Stay within your swimming, snorkeling, or diving training and local conditions.
Do wireless headphones work underwater?
Normal Bluetooth or low-latency wireless signals do not travel usefully through water. Use the manufacturer’s compatible wired waterproof headphones, or vibration when the detector supports it.
Do I need a waterproof pinpointer?
Not for every hunt, but it can help inside a scoop or dark hole. If it may enter the water, its own full-device waterproof rating must match the job.
