Discovery 3300 Metal Detector

However, there are still a fair number of specs that are included in this model. The Discovery 3300 comes with a discrimination system to help eliminate unwanted metals, a headphone jack, target depth display, and 4-tone audio. Check out the rest of the specs that come included in the Discovery 3300:

  • 11 segment target identification
  • Numeric depth indicator
  • No motion deep-seeking pinpoint
  • 7 segment target elimination indicators

How to Use Discovery 3300 Metal Detector

The Discovery 3300 assembly is incredibly easy and requires no tools. All you have to do is put the interlocking pieces together and follow the owner’s manual to get up and running. Once you have it assembled, you’re ready to get started.

Before turning it on, make sure you turn the ground balance knob to the preset position. Then, press the “power” button located on the touchpad. Before you take your new metal detector out for a spin, it’s recommended that you test the search coil with different objects, like metal coins, copper, gold, and iron. You’ll be able to hear how the tones differ for each object and know what you’ve found. Things like nails will not make any sound, as they will have been “discriminated.”

If you’re carrying a cell phone, make sure that you keep it away from the search coils of the metal detector because the electromagnetics may cause interference with your device. The Discovery 3300 has modes for both “motion” and “no motion.” You can sweep your metal detector from side to side in “motion” mode and get tone indications of hidden treasures. “No motion” mode, is considered “pinpoint” mode, and you can hold your device still and pinpoint the exact location of any buried objects.


If the Discovery 3300 doesn’t have enough power for you, there are plenty of alternatives on the market. Check out the following metal detector that might better suit what you need.

Fisher Gold Bug Pro Metal Detector

This particular device is specifically geared towards gold prospecting. This device has real-time, computerized ground balancing, as well as a discrimination mode for coins and relics. If you’re looking for something to go gold prospecting with, the All Metal Mode on the Gold Bug Pro is just what you need. This model is perfect for people who take gold detecting a little more seriously.


For a low-to-mid-range price point, the Discovery 3300 is not a bad device at all. If you’re looking for a device that’s great for family fun in the backyard or on the beach, then look no further. Hopefully, this Discovery 3300 Metal Detector review has given you a better insight into this product and helped you make a better-informed decision. Now all that is left is to grab one, and set off to find whatever hidden treasures lay buried beneath the soil.
