Metal detector Minelab Excalibur II

In this article we are reviewing Minelab Excalibur II metal detector. This is a professional device with 17 operating frequencies for underwater treasure hunting, though it is also good for beach hunting. However, the main feature of Excalibur II is underwater search.

What is this metal detector designed for?

Minelab Excalibur II metal detector was designed to search for lost jewelry, coins, etc. under water. You can submerge the device and go treasure hunting up to 200 ft (60 meters) deep. Excalibur II sees between targets from non-ferrous metals such as gold or silver and ferrous targets.

Proper discrimination adjustment allows setting the device to ignore signals from bottle caps, foil and iron and to detect all non-ferrous targets; the adjustment is performed by means of a controller on the metal detector shaft.

The shaft

It consists of two sections. Standard shaft 1140 mm – 1220 mm (45″ – 48″); Dive shaft 820 mm – 910 mm (32″ – 36″).

Battery holder and control unit are attached to the upper shaft section. There is also an armrest, but many detectorists take it off as a rule.

Here the thing is, that under water it is convenient to hold the device using its battery holder or the shaft section close to the search coil. Hardly ever the device is used in a standard way, when the user’s hand holds the handler and the elbow is fixated in the armrest.

Also, at that the armrest creates additional resistance under water.

The coil

This metal detector is equipped with a Double D 10″ searchcoil and waterproof stereo headphones. The coil provides fast target response and excellent recognition of ferrous and non-ferrous metals. When using a pinpointer mode such a coil has a very precise pinpointer center!

In addition, the metal detector searchcoil has some extra protection by means of a dismountable plastic protection case to prevent the coil bottom from possible mechanical damage when using it on a rocky bottom, for example.

This metal detector is using a new BBS technology. This is a multi-frequency technology, which allows the device to work using several operating frequencies simultaneously.

Most of metal detectors available on the market nowadays use only one or duplex operating frequency from 1 kHz to 60 kHz. Depending on the operation frequency such devices can be set to detect only large or small targets, they may show good performance in some areas and almost lose their sensitive in others.

Soil mineralization, iron rubbish, sea water, target size – all of these have an impact on a metal detector sensitivity.

Unlike other metal detectors, which use one operation frequency, BBS technology used by Minelab Excalibur II broadcasts a signal on 17 frequencies (from 1,5 kHz to 25,5 kHz) simultaneously. The device demonstrates good performance both in fresh and brackish water.

A signal obtained from the searchcoil is processed by the computer and then it is sent to the user via headphones.

This multi-frequency metal detector can detect and identify precisely targets located on maximum depth regardless of soil mineralization or amount of iron rubbish in it.

Minelab Excalibur II metal detector can increase its detection depth with the help of a special RCB technology of the signal amplification. It improves the signal tone obtained from small and deeply located objects, at that it suppresses phantom signals and various noises.

The headphones

The metal detector is equipped with wireless KOSS headphones. They are those to be used under water and they get filled with water. Therefore, before you start treasure hunting, wait for several seconds till they get filled with water.

The sing is that the filling process is a bit noisy and if you start treasure hunting at the same time, you may miss some signals.

The battery

Power supply for Minelab Excalibur II is performed by means of NiMH accumulator batteries 1000 A/h or by 8 AA batteries, which ensure continuous work of the device throughout 14-19 hours.

Sometimes Minelab Excalibur II package set includes plastic box for batteries, a carry bag and a utility belt to ensure comfortable treasure hunting on land.

Waterproofness

The metal detector is a waterproof one and it can be submerged up to 60 meters (200 feet) deep.

The control unit

The control unit case of this device has rather unusual appearance.

This is completely hermetically sealed, tear-drop body of cylindrical shape. Inside it has all the powerful internals of the device. Manual control of the metal detector is performed by means of 5 adjusting potentiometers located on the control unit.

Since Excalibur II metal detector is a device for underwater search, it has no LCD display and no speaker. Therefore, all the data obtained from the target is received by the user through the waterproof headphones.

The device is easy to control even for beginners.

Settings:

  1. Discrimination scale from 1 to 17.
  2. Sensitivity scale from 1 to 10.
  3. Volume adjustment.
  4. Pinpointer function.
  5. Linear discriminator mode.
  6. Threshold tone adjustment.

If we count from the handle that we use to hold the device, the first sliding bar is

Discriminate / Pin-Point Mode. «Disc» is used to ignore the unwanted targets and Pinpoint is a static mode to define precise target location.

The second controller is Threshold control on / off switch – it is used to adjust the threshold tone and to turn the metal detector on/off.

The third control is Volume, which adjusts volume of the signal obtained from the target.

The fourth controller is Sensitivity to adjust the sensitivity level.

Finally, the fifth one is Discriminate control – this is a scale that allows defining which exactly targets are unwanted. This setting can be used together «Disc».

Pinpoint mode in Minelab Excalibur II functions without considering discrimination. This is an important issue, especially if there are several targets located close to each other.

Minelab Excalibur II has automatic ground balance function, which allows working efficiently without decreasing the detection depth both in fresh and brackish water.

Conclusion

Nowadays, Minelab Excalibur II is the best underwater metal detector. Firstly, it is rather user-friendly and settings adjustment process is rather simple.

Secondly, it can work on significant depth. Thirdly, the device uses a multi-frequency technology.

The most essential drawback of this metal detector is its price. However, all underwater metal detectors are quite expensive and this one offers maximal efficiency and functionality for the money.
