Designed as a portable pinpoint metal detector, the underwater metal detector helps users locate metal targets after a larger detector identifies an area of interest. Simply power it with a 9V battery and scan the target area with the waterproof probe. As the probe moves closer to metal, audio and vibration alerts become stronger. Suitable for beaches, soil, lakes, and underwateruse, its fully waterproof design makes it ideal for wet environments andprecise target recovery.

FAQs
Q: What can this underwater metal detector detect?
A: The detector can help locate and pinpoint metal targets such as coins, rings, relics, and other metal objects. It is particularly useful for recovering targets identified by a larger ground metal detector.
Q: Is the battery compartment waterproof?
A: Yes. The metal detector features a waterproof battery compartment as part of its sealed design for underwater operation. Please make sure the battery cover is securely tightened before submerging it in water.
Q: How long is the battery life?
A: It delivers roughly 20 hours of runtime on a fresh battery. Actual usage time varies with battery quality and how often the alarm triggers.
Q: Why is the LED light flashing all the time?
A: Steady flashing LED means low battery. The LED also serves as a handy flashlight to help you see targets in dark or low-light areas while treasure hunting.
Q: Can I use this as a metal detector pinpointer?
A: Yes. The compact handheld design makes the detector suitable for pinpointing targets after a larger metal detector identifies an area of interest. Scan around the target area with the probe to narrow down the exact location.
Q: Is this metal detector suitable for beginners?
A: Yes. The handheld design and straightforward audio, vibration, and LED feedback make the detector easy to operate. It can also be used alongside a larger ground metal detector for more efficient target recovery.
