1st Step

Start the underwater metal search by planning your trip well. Summer is an excellent time for detecting metals inside the water. This is when the water warms, making your body stay in the water for a long time as you search.

2nd Step

Ensure that you know well your metal detector. Know all the device settings and ensure that you know all the basic features and their respective function. For example, features such as discrimination allow you to choose your targets correctly.

Other features include; sensitivity, which allows you to choose how effective and precise your metal detector will be. It also enables you to hove in. The detection mode will enable you to filter out objects. The ground balance helps in accounting for common minerals.

3rd Step

When doing an underwater metal search, it is important to follow an imaginary line and follow it consistently. You can follow it and move within 5 to 6 feet of swipes. Ensure that you keep an eye out for ocean floor potholes.

4th Step

Cover the underwater grounds by effectively sweeping your underwater water detector as you dive in the water. As you dive, ensure you keep the detector about four or five feet deep. As you plummet, sweep it back and forth in the half-circle.

Move your detector in small circles so that you can know the precise location of the object after the beep. Use the detector slowly to identify the exact spot where it beeped from. You can also increase the sensitivity of the detector as you move closer.

5th Step

Knowing the water current is also important more especially if you want a positive result quickly. This is because it helps you show the direction of sand hence giving you ultimate insight into the location where your metal is stuck.
