Minelab Excalibur II Features

17 Operating Frequencies

Way more frequencies than an average metal detector can offer, opening additional opportunities for successful search.

DD Coil

This is one of the most efficient coil shapes for search in highly mineralized waters, or salt waters.

Auto Ground Tracking

The most efficient way to increase mineralization underwater, as the machine tunes itself automatically depending on how the soils change.


Up to 196 feet is a decent indicator proper for deep diving with a metal detector.

Waterproof Headset

Obviously headphones should be high quality and waterproof as well.

Noise Cancellation in Salt Water

Useful feature that prevents false signals by cutting noise caused by mineralization and electromagnetic interference by shifting the frequency.

Minelab Excalibur II Overview

Expert-level metal detector by Minelab, the Excalibur II model, is created for search and metal detecting underwater. This device was developed with complicated prospecting in mind. It is equipped with 17 operational frequencies (BBS multiple frequency technology), and the frequencies range from 1.5 kHz to 25.5 kHz, which is an amazing range.

The device is fully waterproof, it can be operated on the depth of up to 196 feet, and spot small coins, jewelry, and bigger items on the maximum depth. The level of discrimination available in Minelab Excalibur II allows to sort out items made of ferrous metals, and metallic trash. Smart ground balancing not only helps avoid distortion of the signal due to mineralization of soils, but also filters fake signalling caused by salty water. That feature allows to use the metal detector in fresh and salty water alike.

Excalibur II by Minelab is currently one of the best choices for those who are interested in underwater metal detecting and considers prospecting on considerable depth.

Top Features

Excalibur II is stuffed with some cool features you definitely want for productive search underwater, especially in salty bodies of water. The most innovative features include:
Minelab Excalibur II

All these unusual features show that this product was engineered with complicated underwater conditions in mind. Moreover, the manufacturer claims that the device can be moved from land search to beach and shallow water search, to deep underwater search without changing the settings much.

Another interesting feature that should be mentioned is only two search modes – Discrimination and Pinpoint. This feature will enable the user to only change frequencies depending on the expected type of finds.

Search Modes

Excalibur II has only two search modes – Discriminate and All Metal Pinpoint. Some may consider this a drawback, but keeping in mind that this machine is more suitable for underwater and beach prospecting, having only two modes is rather a blessing.

This product is tagged as for “Intermediate” and “Experienced” level of the users, so it is expected that the users already know which frequencies will bring which types of finds. The brand enables the user to decide themselves which frequency to apply for which location. There are 17 frequencies available for prospecting, and changing the frequencies will change the conditions of search.

The Discrimination can be adjusted, as well as the sensitivity level, so the treasure hunter can tune the device to the most optimal combination of settings. Pinpoint mode is another bonus that helps to identify the exact location of the target.


For this underwater machine, Discrimination is one of the most suitable options, allowing to adjust the settings and filter off signals you are not ineterested it. Other tools are less necessary in expected conditions where this detector operates.

All Metal Pinpoint

Having Pinpoint mode underwater is extremely valuable. All Metal part of the feature also makes perfect sense - if you already go for the target, you have considered it worthy of your time, so all-metal sensitivity should be provided to spot it accurately.
