The unique design of the EXCALIBUR II beach and underwater metal detector allows you to use it effectively in or out of the water. Whether working the beach, wading the shallows or diving a shipwreck at 200 feet, the Excalibur II will perform every time.

Powered by Broad Band Spectrum (BBS) technology of 17 frequencies between 1.5 kHz to 25.5 kHz, the amazing depth and accuracy of the Excalibur II continues to amaze long time divers and everyday beachcombers.

For full information this model can be found on our special EXCALIBUR II  page.

Control Box: This encloses the electronic circuitry of the detector. The control box generates the Tx (transmit) signals sent by the coil and processes the Rx (receive) signals detected by the coil. All user selectable functions are located on the front and rear panels of the control box.

Discrimination: The ability of a detector to determine if a located target is made from ferrous metal (iron or steel) or non-ferrous metal (non-magnetic).

Double-D Coils: Two windings of wire that overlap in the shape of two D's (one reversed). The characteristics of a Double-D coil are stability, especially in heavily mineralised ground, good depth and sensitivity and a very thorough search pattern.

Electromagnetic Field: Commonly called the 'signal from the coil'. An electromagnetic field is generated within the wire windings of the search coil and this field is pulsed or sent into the ground. The presence of a metal target in the ground will disturb the pattern of this field and this disturbance is sensed by the receive system of the detector and indicated to the operator by an audible 'beep'.

False Signals: These sound similar to target signals but are caused by other factors. Common causes for false signals are incorrect Ground Balance, hot rocks, signals caused by knocking the coil on obstacles, etc. With experience, the operator will learn methods to minimise false signals and to hear subtle differences between target signals and false signals.

Ferrous Metals: Metals composed of or containing iron. A ferrous item will be attracted to a magnet and is predominantly or completely made of iron or steel.

Ground Balance: The ability of the metal detector to compensate for the effects of ground mineralisation.   For instance: The GPX 500 has 'automatic Ground Balance'. When Ground Balance is used in the Tracking setting it continually compensates for changes in the ground mineralisation.

Halo Effect: After a metal object has remained undisturbed in the soil for a considerable amount of time, a diffusion occurs around the object. This has the effect of the object appearing to the detector to be a larger size.

Hot Rock: An individual rock which has a high degree of mineralisation in comparison to the surrounding ground around it. Due to this difference, the detector does not have the opportunity to Ground Balance to the individual hot rock so therefore gives a false signal. The signal will diminish rapidly by increasing the coil height above the hot rock.

Interference: Electricity or radio waves in the area being detected can cause instability or chattering of the Threshold. Interference commonly occurs due to power lines, underground cables, radar, other detectors or climatic conditions like thunderstorms.

Mineralisation: Most ground contains some minerals, which can cause false ground signals to be detected. Heavily mineralised ground requires different detector processing than does neutral or lightly mineralised ground. Ground containing heavy salt concentrations require entirely different processing again.

Monoloop Coils: Monoloop coils are the style of coil where the multiple strands of wire are wound in a single loop around the circumference of the coil. The field of search of Monoloop coils tends to be cone shaped. They provide greater depth and sensitivity compared to a Double-D coil of equivalent size in low to medium mineralisation.

Non-Ferrous Metals: Metals that do not contain significant levels of iron. Non-magnetic metals such as Gold, Silver, Copper, Brass, Lead or Aluminium.

Pinpoint: The method of determining the precise location of a target prior to digging. Pinpointing uses the design of the search coil windings to determine the exact position of the detected target.

Rx (Receive): Refers to the response or electromagnetic field which is received back by the coil and is used by the control box circuitry to detect a metal item in the ground.

MINELAB   "AUSTRALIAN ADVENTURE CLUB"

When you purchase a Minelab GP or SD Series Metal Detector … Minelab Electronics Pty Ltd provide you with the following benefits:

• Field Tuition (for Australian customers only) in the goldfields on your new detector.
• Your own copy of "Handy Hints and Tips" booklet.
• FREE Minelab Cap.
• FREE Adventure Club Key Ring (including your Membership Number).
• FREE subscription to the periodic Newsletter – "The Minelab Times"
• Exclusive FREECALL 1800 Number for Club Members only.

Joining the "Minelab Australian Adventure Club" is as simple as filling out your Warranty Card and returning it direct to Minelab in Adelaide . When this is received your FREE Cap and Key Ring will be sent out to you along with information on how to enjoy the benefits of the Club.

Field Training Days will be held once every 4 to 6 weeks (depending on numbers) at different goldfield locations around Australia . To allow for individual tuition, training groups will be maximum of 15 members. Minelab’s field trainers are professional prospectors who will show you how to use your new detector, how to set it up to suit different conditions, the general skills of metal detecting and other handy hints.

Morning and afternoon tea is provided, and you will have plenty of time to detect on your own. You also have the option of taking a second “refresher course” in the first 12 months after purchase.

At the completion of the training day, you will receive a detailed booklet that outlines the operations and handy hints you’ve learnt during the day and other useful information.
