Metal detectors are electronic instruments used to detect foreign bodies such as metal items hidden within objects or buried underground. First found around 1960, metal detectors ever since have had several uses in various industries. Check out some of the most popular uses of metal detecting devices.
Security Screening
Prior to the rectangular gantry now standard at airports, magnetometers were the first metal detecting devices used sometime in 1970. Metal detectors both hand held and walk through, are of great utility at public places and sensitive areas to ensure security and evade potential threats from carrying weapons like guns and knives. These are mostly used to avoid illegal and unauthorized entry of metallic objects at airports, metro stations, malls, prisons, courthouses, hotels, clubs etc. Handheld devices precisely locate the presence of metal objects on a person and are extremely portable, easy to use and efficient.
Archaeology
First used in 1958 by a military historian to detect firing lines at a battle, metal detectors began to be used extensively in archaeology. Most archaeologists now, however, discourage the use of metal detectors by seekers of artifacts and site lovers as their activity usually disrupts archaeological sites. Since ordinary seekers find objects without archiving or recording its context, the cultural and historical significance of the object is lost. To resolve this issue, many countries impose certain rules on hobbyists and ordinary people using metal detectors on specific sites.
Industrial metal detector
Developed by Bruce Kerr and David Hiscock in 1947, industrial metal detectors were first used by Mars Incorporated to inspect mars chocolate bars for adulterated items. Later industries dealing with pharmaceuticals, food, beverage, textiles, garments, plastics, chemicals etc. incorporated metal detection as a compulsory safety measure in the production process. Food manufacturing industries use metal detectors as a precaution to check for metal shards from broken machinery in food items during production and packaging. Metal detectors help spot foreign objects in food items before it is packed. Garment factories make use of metal detectors in sewn garments to ensure that all garments are free from any traces of metals like needles, broken needles etc. When contaminated objects undergo metal detectors, an unequal disturbance is felt in the device that further creates a small electronic signal and some amplification. Once that happens, a mounted device is signaled to remove foreign products from the production line. All this happens automatically to avoid uninterrupted manufacturing process in big factories.
Hobby
Metal detectors are used in a big way as various types of hobbies as well. Coin shooting, prospecting, treasure hunting and beach combing are some of the popular activities that use metal detectors to locate lost, hidden and distant objects.
If you are looking to go fishing, Texas is probably the best place for you to go try out your luck. It becomes the best state for fishing as it has almost all varieties of fish. If you are looking for a saltwater fish or a freshwater fish, you can go to Texas for fishing. The state has all types of fish for everyone’s needs. Some of the hotspots in the state are outstanding in terms of quantity, quality, and in some cases both. The ideal way to go about fishing in any part of the country is to keep an eye out for the peak times. Read along to find out what to find in spring and summer according to the fishing reports of Texas.
Spring (March, April, May)
Spring is fairly the best time for you to go fishing for largemouth fish, according to the fishing reports of Texas. Out of the 50 biggest largemouth fish that are available in Texas, 34 can be found in Lake Fork. The record for the biggest largemouth fish is 18.18 pounds, which was also found in Lake Fork in March. If you go to the mid-term of Spring, you would have to move to Lake Buchanan and get your hands on the blue catfish. Lake Buchanan also has a good number of channel cats and flatheads. Lake Texoma if where you would want to be towards the end of the season. The Stripers that have migrated during Feb and March start to show up in the open water areas.
Summer (June, July, August)
Red snapper is the primary fish to be found during the initial stages of summer in the Gulf of Mexico. However, it is an issue among the fishery officials due to the quotas and season dates. The fishing reports of Texas also state the fish to be the most wanted fish as well as one of the tastiest fish in Texas. Lake Tawakoni is the home for Channel Catfish that are found in abundance during the mid-term of the summer. West Tawakoni is also deemed as the “Catfish Capital of Texas.” The annual catfish haul takes place during the summer and it is an event you must not miss out on. August would bring in the end of the summer and Laguna Madre is the place to be so that you can get your hands on some fresh Speckled Trout. Fishing reports of Texas have shown that the “Mother Lagoon” is one of the best places for you to go fishing during this period.
If you are looking to go fishing on a Sunday afternoon, there is one thing you must keep an eye on before heading out of home the fishing report. A fishing report is written by people who go fishing, it essentially talks about the type of fish available in a certain area, the weather conditions, tidal waves, and the intensity of the ocean current. A fishing report is ideally used by fishermen to know where they can find a certain type of fish they are looking for. It helps them determine where to cast their lines.
The water temperature can define the activeness of the fish in that area. If the temperature is high, then the fish would not move around a lot as it will be significantly hot. Similarly, if it is cold, then they will not move at all. To sum it up, unless the temperature of the water is pleasant, the fish will not indulge in a significant amount of movement. It is difficult to lure resting fish as they will not bite or chase the lure.
Another important component of a fishing report is the water conditions. Whether the water is still or moving, the pace of the movement (if any), if the water is muddy or full of debris are factors to be kept in mind. If the water is moving too quickly or there is a significant amount of mud in the water, then it will be a bad day to go fishing. The fish will not be able to exercise complete control on their movement and will not be able to see the bait if it is too muddy.
These reports are made according to different regions which help the fishermen decide when and where to go fishing. For example, fishing reports of Texas, Washington state, green bay etc. A fishing report of Texas would broadly include the weather condition, wind speed, when the fish are biting, where they are biting, and the types of bait that are effective.
Fishing report of Texas
Texas is home for Saltwater fish like Black Drum, Redfish, Spanish Mackerel, and many others. If you are going out fishing in this season you will come across Snapper (red), Spotted Seatrout, Flounder, Redfish, and Black Drum. The best time to go fishing during spring is late-afternoon and early evenings. The fish bite due to a high metabolism and digestion. The sun overhead helps the fish move around adequately.
