Magnet Fishing in the Ocean

Magnet fishing is a popular hobby that involves using a strong magnet attached to a rope or chain to search for metal items at the bottom of rivers, lakes, and other bodies of water.

But what about magnet fishing in the ocean? Is it possible? The answer is yes—but there are a few things you should know before you attempt it.

Safety First

When attempting to magnet fish in the ocean, safety should always be your top priority. It can be dangerous due to the unpredictable nature of large bodies of water.

Make sure you are well-prepared with all of the necessary equipment such as life jackets, flares, first aid kits, and other safety gear.

It’s also important to check local laws and regulations before beginning your adventure—some areas may have restrictions on magnet fishing due to environmental concerns or other reasons.

What Can I Expect?

The ocean is vast and home to countless items that may not be visible from the surface. It’s likely that you won’t find any items that have been submerged for too long due to corrosion or damage caused by saltwater exposure.

That being said, if you are lucky enough you may find coins, jewelry, historical artifacts, or even lost keys!

Keep in mind that if you do come across something valuable like jewelry or coins there may be laws in place preventing its removal from the waterbody so make sure you research those as well before starting your hunt.

Equipment Matters

It’s important to use high-quality equipment when attempting sea-based magnet fishing as it can be more challenging than freshwater magnetic fishing due to higher levels of debris and corrosion on objects found underwater.

Consider investing in a sturdier rope than what is normally used for freshwater searches as well as an extra-powerful magnet with plenty of pull strength (at least 1500lbs).

A waterproof wetsuit is recommended if you plan on submerging yourself during your search since most magnets cannot reach objects deeper than 10 feet below the surface without assistance from a diver.                                                                                                          


Magnet fishing in the ocean can yield interesting findings if done correctly and safely. To successfully navigate this endeavor equip yourself with all of the necessary safety gear and research local laws beforehand so you don’t run into any legal trouble while out on your adventure! Have fun exploring!
