Overview of the Features

Here’s an overview of the Kuman KW30 Metal Detector:

  • Medium Detection Distance

A decent detection range will guarantee that you find whatever lurks just below the surface. With the KW30, you will be able to trace any metals within a range of zero to five centimeters. While this may not be the broadest range, it is decent for small detectors.

  • Partial Waterproof Exterior

One of the critical features for any metal detector is that it needs to be waterproof and be able to resist a splash or a quick dunk in the water. The IP level of the device is 64, which enables you to partially submerged the equipment. You’ll be able to submerge the detector below the lights and switches, but the rest is not waterproof.

  • High Sensitivity

With a high sensitivity sensor, you’ll be able to pinpoint where objects are accurately using three sensitivity levels. You can use it indoors, outdoors, and to sense non-magnetic items.

The KW30 can sense stainless steels 302, 304, and 316, which are usually not detectable through a metal detector. The sensor also detects up to 360 degrees, making it easier to locate objects nearby.

  • Audio and Vibration Alert System

When an item or object is detected, you will be notified via a LED light, audio beep, and vibrations. Having three different indicators can help prevent you from missing a signal. The audio and vibrations both get more intense and frequent as you get closer to finding metals.

  • One-Touch Operation

If you’re running into issues detecting a specific object, you can always use the quick button. It is designed to narrow down the detection range and only sense larger objects in the area. This can be helpful if you’re detecting multiple objects and are unsure of where to dig.

  • Flashlight

The LED light indicator on this device can double as a flashlight, which is always a good addition regardless if you’re hunting in the morning or at night.

How to Use This Device

When it comes to using the Kuman KW30, it is merely a matter of when and where. Since there are not many controls, all you will need to do is power the device on and watch it do its magic.

If there’s metal nearby, the three-step detection will alert you immediately. Once the alert goes off, it’s a matter of finding the right location. You can use the quick button to help sort smaller objects from bigger pieces that will be worth the dig.

As you get closer to the item, the three-step alert system will become more intense, and you’ll know when you’re right over the treasure.



While the Kuman KW30 may be an excellent choice for some, it may not be able to function well in your surrounding environment. An alternative that is fully submersible and is ideal for wet or humid locations might be what you’re looking for. For that, you can give the Monsunece Metal Detector a try.

Lastly, the one-touch operation helps switching between power-saving mode and full power mode easier. All of these qualities are what make this device a step up from the Kuman KW30.
