This is an amphibious machine that is as helpful underwater as it is out of it! For USD 1,499.00, take Minelab's unique Broad Band Spectrum (BBS) technology with you on your adventure. This, combined with superior ground rejecting technology, puts the Minelab Excalibur II at the top of our list. Use it seamlessly from underwater depths of up to 200ft to the land, beach, and wet sand conditions.

• Garrett Ace APEX: simply amazing!

Garrett has created a great addition to their metal detector family. Thanks to Ace APEX's Multi-Flex technology, this machine becomes one of the most versatile waterproof detectors in its price range (USD 497.21).

This detector introduces a new look to the Garrett range while maintaining easy-to-use screen functions.

• Quest XPointer Scuba Tector: great for less.

This is a lightweight, handheld detector that won't weigh you down. Go treasure hunting for hours at a time, thanks to the Scuba's Li-poly battery. This easy-to-use tool can go with you to the ocean's depth, as it can be submerged up to 197 feet deep.

This detector is a good option if underwater-detecting is not your main focus, as it is cheap (USD 179.99) and not the most long-lasting underwater detector in the market.

• Treasure Products Vibra-Tector 740: your pinpointer of choice.

Explore up to a depth of 100ft with this self-calibrating PinPointer. This tool offers a unique way to control it, with no buttons and a tilt-on/tilt-off design.

What are the different types of underwater metal detectors?

Underwater detectors aren't just waterproof; these metal detectors work differently from others to detect all types of metal through water, wet sand, and different textured ground.

We could divide them into Pulse Induction technology and the Very Low-Frequency (VLF) detectors.

PI detectors work by sending rapid electronic pulses that detect metals without being affected by water and wet minerals.

On the contrary, VLF metal detectors can be more affected by mineralized ground. These are extremely sensitive to coins and jewelry but won't work for small pieces of lesser metal.

Additionally, Minelab introduced their Broad Band Spectrum detectors, which work with their patented multi-frequency technology. BBS detectors become more aware of their surrounding environment and target thanks to this broad range of frequencies.
