Dive into Adventure: Underwater Metal Detecting Gear and Techniques

Underwater Metal Detecting Gear and Techniques

Metal detecting isn’t just for landlubbers; it can be done underwater too. In fact, the practice of underwater metal detecting has been around since the early 1960s when Jacques Cousteau used a metal detector to explore shipwrecks in the Mediterranean. Since then, technology has advanced greatly, making it easier than ever to find lost treasure beneath the waves.

If you’re interested in trying your hand at this fascinating hobby, here’s what you need to know about underwater metal detecting gear and techniques.

Gear

The most important piece of gear for any underwater metal detectorist is obviously their metal detector. Unlike land-based detectors which use VLF (very low frequency) or PI (pulse induction) technology, underwater detectors use pulse induction exclusively because saltwater interferes with VLF signals.

When choosing an underwater metal detector, look for one that’s designed specifically for this purpose. These typically have a waterproof housing and are rated for deep water use. Some popular models include the Minelab Excalibur II and the Garrett Sea Hunter Mark II.

In addition to a good quality detector, you’ll also need other gear such as:

1. A dive mask: You’ll want something with a wide field of view so you can see all around you.

2. Fins: It’s important to be able to move quickly through the water so fins are essential.

3. Dive weights: Depending on how deep you plan on diving and how much equipment you’re carrying, you may need additional weight to help keep yourself submerged.

4. Wet suit/dry suit: If diving in cold water temperatures or long periods under water will require extra protection beyond swimming shorts or bikini tops.

Techniques

Once outfitted with your gear it’s time to get started using proper techniques that will maximize your chances of finding valuable treasures below sea level:

1. Research potential sites: Before you start searching, do some research to identify potential sites where ships may have sunk or where people may have lost valuable items. Popular spots include old docks, jetties, and beaches that were popular in the past.

2. Get permission: You’ll need permission from property owners and any relevant authorities before you begin your search.

3. Know your equipment settings: Make sure you’re familiar with all of the settings on your metal detector so you can adjust them as needed for different conditions.

4. Practice good technique: When sweeping an area with your detector, move slowly and methodically back and forth in a straight line. It’s important to keep the coil close to the bottom but not touching it so as not to miss anything hidden in the sand or mud below.

5. Be patient: Underwater metal detecting requires patience since finding something valuable can take time and effort.

Conclusion

Underwater metal detecting is an exciting hobby that combines adventure, history, and treasure hunting all into one activity. With proper gear selection, knowledge of techniques, and a little bit of luck anyone can find treasures beneath the waves! So get out there and explore what lies beneath our oceans!
