This feeling of security can be easily created in any office building, school, apartment complex, or other confined area. It is achieved by establishing one central entrance and exit point that is outfitted with metal detectors.

A metal detector uses the principles of electromagnetic induction to detect metal objects. Within the tool is a coil that, when introduced to a current, creates a magnetic field. Once this magnetic field comes in contact with a metal object such as a knife the tool is alerted to the presence of the metal.

There are two options when considering metal detectors, the walk through and the hand held. Walk through metal detectors offer quick and effective processing. They alert security officers to the presence of potentially dangerous metal objects such as guns, but allow for people to pass through quickly so as not to create inconvenience for those entering the building.

Hand held metal detectors are also effective and are a more affordable option. They offer easy to use protection and direct information regarding where the metal objects are located. In addition, the hand held metal detectors are effective in determining the presence of a weapon away from the security checkpoint. Ideally, the walk through and hand held will be used in conjunction with each other for maximum protection.

An additional effect of a metal detector is the deterrence factor. Once it is established that those desiring admittance will have to pass through a metal detector, hand held or otherwise, few people will attempt to bring in any source of weapon. This means that your building is removed from the list of potential targets. Because metal detectors are a preventative measure they stop the threat of an attack well before anyone can be injured.

When searching for a merchant that carries metal detectors it is important that you seek one who is reputable and provides quality products. A great place to look is at http://bljsselfdefense.com/index.php?target=categories&category_id=56. This company offers a wide variety of items, including metal detectors, and provides consumers with education on self defense. In addition to the online resources, BLJ’s Enterprises supplies its customers with personal attention to help ensure that they receive the self defense tool that is right for them.

RESOURCE BOX:

A housewife has discovered a 15th-century gold treasure valued at £250000 with a metal detector. The find is thought to be part of a high-quality reliquary or pendant, and depicts the Holy Trinity. It is the first item of any real worth that Mary Hannaby has found in seven years of combing fields and beaches. Mrs Hannaby, 57, from Hemel Hempstead, Hertfordshire, made the discovery while out on one of her regular six-hour Sunday detecting walks with her son Michael, a 33 year-old wood carver …

We visit the site of former ‘Coal King’ and Parliamentarian Lewis Thomas’ mansion which was constructed in 1888 and demolished in 1937. The mansion had three stories, its own electrical power generating plant, 49 rooms and it even incorporated an hydraulic lift (elevator), quite a rarity in an 1880s Australian country house! The house was serviced by a permanent staff of eight and was the focus of social activity for the large Welsh mining community who came to Australia to work the coal deposits in the area. Unfortunately, following the death of Mrs Ann Thomas in 1930 with no living heirs, the mansion was sold to a coal mining company in 1936. A series of subsidence events under the foundation in the old coal workings finally spelt the end for the structure and it was demolished in 1937. We hope you enjoy this historical outing and a bit of investigative bush archaeology. Thanks for watching and please take the time to visit our blog www.nqexplorers.com

adventureswithjim.com presents SHIPWRECK SUNDAY. Well, it was a sunday when this relic hunt started at least! Lots of great metal detecting on the beach, if you don’t mind the occasional 20 ton shrip wreck relic. Got some tourist gold too, and that’s never a bad thing. Maybe the opening anamation reveals a bit too much about my age and state of sanity, but this is kind of normal for my demented treasure hunting mind. Music by Kevin Macleod.
