The best metal detector for the beach is always the top waterproof metal detector, but you also want a device that is either multi-frequency or pulse induction. For an underwater metal detector, there are handheld versions and more budget-friendly options.

If you have a penchant for finding buried treasure on a beach, you need a specific set of functions.
On both wet and dry sand, the top beach metal detector should be pulse inductive (PI) rather than Very Low Frequency (VLF). Different coil sizes and whether it’s weatherproof, waterproof, and submersible also influence which option is the best metal detector for the beach.
If you SCUBA dive or snorkel looking for buried pirate treasure, an underwater detector is right for you. The best underwater metal detector should be waterproof and submersible for many feet and have a high capacity for dealing with mineralization.

This metal detector is chock-full of features. If you’re a fan of shore hunting [1] and want to know the best detector for the beach and price is not a challenge, then the Minelab CTX 3030 Standard Pack Metal Detector may be just the device for which you’ve been searching.

If you are a PC-user (not Mac), you can take advantage of the CTX’s GPS mapping function. Target separation and a full-color display make find identifications a cinch.
Usually, PI detectors cannot discriminate between targets well, but the Smartfind 2D Discrimination feature of the CTX levels the playing field by adding to the device’s accuracy and sensitivity.

- Updated armrest lock
- Full-color display
Cons
