Metal detectors are now commonplace in airports around the world, but this wasn't always the case. The use of metal detectors in airports was introduced in the 1970s, with New Orleans International Airport becoming the first airport to use walk-through metal detectors in July 1970. This new security measure was implemented in response to an increase in airplane hijackings. Today, metal detectors are standard security features in airports, alongside full-body scanners and luggage X-ray machines. While the use of metal detectors in airports is a long-standing practice, the regulation of metal detecting as a hobby in Wisconsin is a separate matter, governed by the Archeological Resources Protection Act.

Metal detectors at Wisconsin airports are regulated by the Archeological Resources Protection Act (ARPA)
Metal detectors have been used in airports since 1968, with Eastern Airlines purchasing a walk-through metal detector for its Gate 14 at Washington National Airport. In 1972, metal detectors became more widely implemented in airports due to an increase in airplane hijackings.
Walk-through metal detectors and hand-held security scanners are now standard security measures at airports. While I cannot find a precise date for when metal detectors were introduced in Wisconsin airports, it is safe to assume that they were implemented in line with national security developments.
In Wisconsin, metal detecting is forbidden on state-owned land, including state and national parks, without a permit. However, there are some exceptions to this rule, and permission is sometimes granted. Most of the land in Wisconsin is considered private property, so it is crucial to understand the laws and obtain permission from the landowner before detecting or digging for treasure.
Wisconsin's rich history, Great Lake coastline, and river systems make it an attractive site for metal detecting. Metal detecting is a popular activity in Wisconsin, with enthusiasts searching for lost jewelry, coins, and even lost treasure.

Metal detectors have been used at airports since the 1970s
The early 1970s saw the first widespread use of metal detectors in airports, with New Orleans International Airport becoming the first airport to install walk-through metal detectors in July 1970. The use of metal detectors became mandated in 1973 when the Federal Aviation Administration (FAA) required all passengers to be screened before boarding a flight. This implementation was in response to the surge in airplane hijackings during the 1960s, with 40 hijackings in the US and 89 worldwide in 1969 alone.
There are two primary types of metal detectors used at airports: walk-through metal detectors and hand-held security scanners. The walk-through metal detector is the most common type, and these were initially designed to detect metal components in weapons. However, they will pick up on any metallic object. The hand-held security scanners, or wands, are used as a secondary measure when the walk-through detector alarms.
Over time, airport metal detectors have evolved, and in 1995, an advanced detector was developed that could pinpoint the height of the metal detected, expediting the security process. Following the terrorist attacks of September 11, 2001, security measures were further intensified, with the Transportation Security Administration (TSA) taking charge of security in the US. These heightened security protocols included the screening of all luggage through X-ray scanners, restrictions on liquids, and enhanced scrutiny of electronic devices.

Metal detectors were first used at New Orleans International Airport in July 1970
Metal detectors have become a common feature of airport security, with all airports in the United States serviced by scheduled airlines now employing some form of metal detection to ensure passengers are weapon-free. Metal detectors were first introduced at New Orleans International Airport in July 1970, marking a significant milestone in aviation security. Prior to the 1970s, there was very little security at airports, and passengers could freely carry items on board aircraft. However, a series of hijackings in the 1960s, including 40 hijackings in the US alone in 1969, prompted the need for increased security measures.
The walk-through metal detector, similar to those still used today, was first installed at New Orleans International Airport on July 17, 1970. These metal detectors were designed to detect metal components used in weapons but would, of course, set off an alarm for any metallic object. Initially, it was not mandatory to screen all passengers, and the walk-through metal detectors were likely used alongside selective screening.
The introduction of metal detectors at New Orleans International Airport set a precedent for airport security, and other airports soon followed suit. By 1972, magnetometers, a type of walk-through metal detector, were being implemented at airports due to increased incidents of airplane hijackings. These magnetometers were originally used to detect metal pieces in logs but found a new purpose in enhancing aviation security.
While metal detectors were a crucial step forward, they were just one part of a multi-layered security approach. Other tactics employed included sky marshals on planes, behavioural profiling of passengers, and the use of X-ray scanners to inspect carry-on luggage. The combination of these security measures has helped to make air travel significantly safer and more secure.

Metal detectors are used to find specific lost personal items
Metal detectors have been used in airports since 1972, as a security measure to prevent the hijacking of airplanes. They are also used to find specific lost personal items. Metal detecting is a hobby that can be enjoyed by anyone with minimal training and can be a great way to spend time outdoors. It can also help to clean up the environment by removing trash from the ground.
When using a metal detector to find lost items, it is important to familiarise yourself with the instrument and its different settings. This can be done by reading the instruction manual and practising with small items made from different types of metal. It is also important to be aware of your surroundings and to obtain permission from landowners before searching on their property.
There are several types of metal detectors, including walk-through detectors and hand-held detectors. Metal detectors can be used to find a variety of lost items, such as property markers, lost keys, machine parts, tools, fishing equipment, and loose change. Some items found with a metal detector may still be in working order, while others may be rusted or damaged.
If you find an item that appears to have been stolen, such as a bag of jewellery, it is important to report it to the local authorities. Similarly, any items that appear to be of cultural or historical significance should be reported to an expert for analysis. If you find an item that you believe someone may want to be returned, you can try to locate the owner by checking with local police stations or posting on social media. Other items that can be done with found objects include recycling, reselling, or reclaiming them for personal use or display.
Metal detectors have been used in a variety of settings, including airports, prisons, and courts, to enhance security and prevent dangerous incidents. They have also been used to locate lost personal items, historical artefacts, and buried explosives, showcasing their versatility and usefulness in various contexts.

Metal detecting is a popular hobby in Wisconsin
Wisconsin's metal-detecting laws can be a little confusing at first, especially as the state is not a popular destination for treasure hunters. The hobby is regulated by the Archeological Resources Protection Act (ARPA), a federal law that preserves items of historical and cultural significance. This law prohibits the removal of man-made objects over 100 years old from public land. However, it does not apply to private property, where metal detecting can be carried out with the landowner's written permission.
Within Wisconsin, there are specific regulations for metal detecting in certain areas. For example, in the city of Cedarburg, metal detecting is prohibited on town property without authorisation from the Town Board. Additionally, metal detecting is not allowed within recorded archaeological sites without approval from the DNR archaeologist, and archaeological materials 50 years old and older cannot be removed from their locations.
For those interested in the hobby, there are some prime spots in Wisconsin that offer fruitful ground for metal detecting. La Pointe, an unincorporated community with a population of around 250, is a popular tourist destination with a rich history, making it an ideal location for metal detecting. The ghost town of Kaiser, which was founded in 1901 and saw a population boom in 1905, is another intriguing site for metal detector enthusiasts. Although little remains of the town above ground, reminders of its brief prosperity are often discovered beneath the surface.
Wisconsin's metal-detecting hobbyists contribute to the preservation of the state's historical and cultural artefacts, while also enjoying the thrill of the treasure hunt. With its diverse landscapes, extensive history, and varied regulations, Wisconsin offers a unique and exciting experience for metal detector enthusiasts of all levels.
