There are many different kinds and styles of metal detectors - gold detectors, coin and jewel detectors, beach-hunting detectors, underwater metal detectors, handheld and walk through metal detectors In 1881, Alexander Graham Bell constructed one of the world’s first metal detectors in an attempt to find an assassin's bullet in President James Garfield. Fischer patented a portable version in 1931.
Detecting Metals in Water
Many people are involved in metal detection underwater. Most of these people would prefer to hunt metals on beaches. There are many benefits that one can get from detecting metals in beaches. Most of the people go on these types of metal detecting trips not because they are after the elusive treasures, but because of the relaxation that it gives. Well, perhaps the treasure is the ultimate reason why they do this, but what keeps them coming back is the experience itself. Going on a water detecting trip to the beach is one of the most relaxing activities since the beach offers sights and sounds that no other place can offer. The waves, the birds, the sand and the people, what more can you ask for? Treasure, perhaps.
So what does one need to do to be able to make his metal detecting trip to the beach a worthwhile one? Here are some ideas.
1. Get the right equipment
Taking an ordinary metal detector to a beach (water) metal detecting trip is probably not a very good idea. If you plan to do this activity for a long period of time, it would be best to get the appropriate equipment for the job. There are many models today that offer water-proof features and can read through water and sand better than other models.
Metal detectors using PI (Pulse Induction) technology often makes use of a single coil or even a series of coils that works as a receiver and the transmitter. The short bursts of electricity are allowed to pass through a coil or wire which causes magnetism. ome detectors have more ways of adjusting the "fit" to the person. Some of the other ways that detectors adjust are that the arm cup can be raised or lowered, and the box containing the board and controls can be taken off of the pole and mounted in a small pouch. Many people say to us "I have always wanted to do this!"
Any place there is construction and the ground is being cleared, that is a great place to start treasure hunting. Successfull treasure hunting starts with having the right metal detector. But which type of metal detector should you get? Complete info on metal detectors and treasure hunting at http://detect-metal.info.
Any place that someone would spread a towel would be a spot to loose something in the sand. Change could fall out of a pocket when getting in or out of a car. Where ever a concession stand might have been is a good area to search. Look for places that people might have gone after dark for a romantic interlude. A good time to check out the beaches is after a large storm.
Youve got to buy a metal detector that could withstand normal wear and tear longer than its competitors. The longer the metal detector can serve you, the better your return on investment will be. For walking speed, remember the paint rollerr analogy above. As long as you are painting the entire surface of the ground and not missing any spots, you are not walking too quickly. However, if you find that your imaginary paint is missing areas, you need to slow down your pace.
2. Plan your trip
Planning a water detecting trip at the beach is an important factor which can determine your success and can influence your experience in general. Beaches are very busy during weekends and it is perhaps not a very good idea to detect metals during these times. You will want to go treasure hunting on week days if you can because there are not as many activities going on at the beach. This will give you more space to roam around.
3. Spot the other beaches
Find out more about metal detectors at metal detector info site. If there are beaches in the periphery which are not as popular as the other beaches, try them out! There's no harm in doing so, and arguably, the chance of finding good stuff there is higher.
4. Get a map
Purchase any map that lays out the entire beach frontier. Try to map out your directions and mark the spots where you have been; this is especially helpful for people who do not have a good sense of directions.
5. Make sure you don't leave your marks
Cover your holes so people don't get injured and the beach doesn't look messy. These are just some ideas on detecting metals in the water. Try to enjoy the experience and you'll find it a treasure in itself. When hand-held detectors are switched on, a red signal pattern in transmitted from the coil to the ground. When the signal comes in contact with a metal, it interrupts the signal and the detector alerts the user with an audio signal and flashing lights.
It is responsible for receiving frequencies that bounce back from the object that the coil detects. This type of detector is best for identifying different types of metals.
Some users put a rubber band around the knobs to keep them from moving or becoming loose. You should buy a metal detector that is light weight. This is important when you are detecting things on a riverbank or body of water. Most metal detector companies also offer supplementary services like designing, material sourcing, prototyping, short run manufacturing, upgrading or re-designing, assembly services and specialty packaging.
