The review

So, this what you’ll find in the box:

  1. A handler with a control unit and an armrest.
  2. Two shaft sections.
  3. Fixation system for a coil.
  4. The coil and the cable.
  5. User’s manual.

The shaft

All Bounty Hunter metal detectors of Discovery product line have the same design. Their shafts and armrests look the same. Only the color of plastic differs and the control unit appearance.

Bounty Hunter Discovery 3300 has adopted the design from the previous models. It has two shaft sections: 8” search coil is attached to the bottom section and on the upper one you will see the control unit, the armrest and the handle, which is rather convenient by the way.

The bend of the upper shaft enables using the device conveniently. The armrest can be shifted along the shaft. The bottom support allows to put the metal detector on the ground and make sure that it stays clean.

You can adjust the device length to your individual parameters by means of the adjustment holes on the shaft section.

The coil

Bounty Hunter Discovery 3300 metal detector has 8” concentric search coil. It demonstrates rather stable performance on most of ground types and it easily stands temperature differences.

Another important property of Discovery 3300 search coil is its waterproofness. Due to this fact underwater treasure hunting is possible as well as beach hunting, but you should keep in mind that you can submerge the metal detector, but the control unit should be kept above water.

The search coil shell is made from solid plastic, which is a durable synthetic material. It is wearproof and impact-resistant, however getting a protection case for the coil will be a good idea.

The metal detector has 6.7 kHz operating frequency. This is a multi-purpose frequency, which to the same extent enables searching for small and rather large targets. This means that Bounty Hunter Discovery 3300 should be considered a multi-purpose metal detector model adapted to any treasure hunting types.

Unlike 1100 metal detector model, models 2200 and 3300 enable using other search coil types — 10-inches and 4-inches coils.


Headphones are not included into the device package set. However, you can connect headphones to the device, since it has a 1/4″ jack plug for them.

The battery

The metal detector uses two 9 V batteries as a power supply. Under normal conditions of operation this energy is enough for 30-40 hours of continuous device work.

There is a way how you can prolongate the metal detector operation time – this is to use headphones; there is a special jack plug for them on the control unit. You can also use accumulator batteries as a power supply for the device, there is a wide variety of them on the market nowadays.

The control unit

The front panel of the control unit has a large high contrast LCD display on it, touch-sensitive keys for settings and navigation as well as a switch for ground balance function adjustment.

Bounty Hunter Discovery 3300 control unit is rather small sized and light weighted, which doesn’t disturb the device balance and makes the treasure hunting process quite convenient.

There are three indicators for target identification. These are: discrimination scale, that demonstrates to which specific segment the target belongs; digital indicator of the target electrical conductivity to specify the object type; 4 tones of target sound response, though mostly experienced diggers rely on them.

Search modes

The metal detector has two search modes: the main one – dynamic mode with discrimination, which is used constantly.

But you can switch to the static mode ‘all metal’, this is when the device will provide a bit higher detection depth, but you’ll here signals from completely all ferrous objects in the ground.

This mode is basically to detect the target center and it is used when digging the target, since it guarantees that you won’t damage a valuable thing with a shovel.

Discovery 3300 has several modes of operation. Together with standard discrimination and All-Metal, it has Notch and Zap modes. They can help to exclude some unwanted groups of objects.

Discovery 3300 is even more advanced. It has 11 segments discrimination scale, VDI numbers displayed and possibility of manual ground balance adjustment.

Displaying possible target detection depth and PinPointer function make this device the most professional one in the whole Bounty Hunter Discovery product line.

All the device models have discrimination adjustment and a filter, which is called «Notch». By means of it you can exclude the selected segments from the whole discrimination scale, regardless of their number except the far-right segment. Function Zap is responsible for it.


However, besides the detection depth there are other important parameters. For example, you should avoid objects which you don’t want to detect. Bottle caps, nails and other unwanted targets can be ignored by Bounty Hunter Discovery 3300, since it has an excellent adjustable discrimination scale consisting of 11 segments.

Each segment corresponds to a metal type or a target type that has some specific individual physical properties.

At that the sector corresponding to iron has three segments and this was done for a reason.

Gold as a low conductivity metal can get into the iron discrimination sector, that’s why you can adjust your Bounty Hunter Discovery 3300 so that it’ll ignore ferrous targets, but it will still receive signals from golden objects, especially from those that are often found in a controversial discrimination sector – chains, earrings, etc.

Bounty Hunter Discovery 3300 has three target identification indicators, that are used by detectorists to decide if the target is valuable or not. Marker on the discrimination scale shows to which segment the target belongs.

The digital indicator (3 digits) displays conventional electrical conductivity value of the detected object and it becomes rather useful when verifying the target.

To make the metal detector ignore repeated unwanted objects you should use ZAP button, after waving the coil above this object. Such a function will be especially useful during beach hunting, where such targets as bottle caps will be encountered quite often.


Sound indication of the device uses 4 sounds with different height of pitch. So, sound response from the target is the third indicator. As a rule, experienced diggers base their judgments on the latter. To take full advantage of this indication type, the metal detector has 4 target response tones!

Depending on the tone you hear, you can quickly understand what is under the device search coil and whether this object is worth digging.

Ground balance

The ground balance function has both manual and automatic adjustment. Bounty Hunter Discovery 3300 are using Squelch-Tech® system aimed at decreasing and elimination of noises on ground with complicated conditions.

Ground balance function in the earlier models is adjusted automatically, while in 3300 you can do it manually as well.


The device advantage is its sufficient detection depth (considering its price), it is rather light-weighted and perfectly balanced. This metal detector is easy to master even for beginner detectorist, it doesn’t have any complicated settings or adjustments.

It’s plain and simple, turn on the metal detector and start to wave the coil. That’s it. Let’s take a look at the device characteristics in detail.

If comparing this metal detector with Teknetics devices, 3300 model is close to Teknetics Eurotek. However, the device control is more complicated, so it won’t do as one’s first metal detector or a device for a kid.
