Tips for Successful Underwater Metal Detecting

Underwater metal detecting presents unique challenges. The water can affect sound and visibility. Here are some expert tips to help you succeed. These techniques will increase your chances of finding those hidden treasures.

Listen Carefully to the Tones

Your detector will make different sounds for different targets. Learn to distinguish between good targets and junk. Pay attention to the pitch and strength of the signal. A strong, clear signal is often a good sign. Weak or broken signals might be junk.

Master Your Sweep Pattern

Sweep the detector coil slowly and evenly. Overlap each sweep by about half the coil’s width. This ensures you cover the area thoroughly. Avoid sweeping too fast, as this can cause you to miss targets. Keep the coil parallel to the ground.

Use a Pinpointer for Accuracy

Once you get a signal, a pinpointer is essential. This is a small, handheld detector. It helps you pinpoint the exact location of the target in the soil. Digging is much easier and faster with a pinpointer. It saves time and reduces the amount of digging needed.

Digging Techniques Underwater

Digging underwater requires patience. Use a small shovel or scoop. Carefully remove the soil around the target. Be gentle to avoid damaging any artifacts. Once you have the target, use your pinpointer to confirm. Always fill in your holes neatly.
