Thoughts on equipment selection from a national expert!
Each and every day I am asked -- "Tell me which detector is the best detector made?" I think that is a fair question, considering that when people buy a metal detector, they will be spending considerably more than $1.98! There is, however, a basic flaw in the question. The question should be modified to ask "Tell me which is the best detector for me?" This last question is best answered with a series of questions.
Have you ever used a detector before? If this is a first detector for you, then you should consider your usual purchasing habits as they relate to other items. Do you generally buy top of the line products with a lot of features, or do you like simplicity? A good example might be a camera. Do you like a "point and shoot" type, or do you like to be able to make a lot of adjustments? Think of this when looking at detectors.
How much money have you budgeted for this detector and how much time do you expect to devote to this sport? These two issues should be considered together. If you plan to detect many hours a week, you probably will want to have a detector with more electronic features than if you plan to spend an occasional few hours at the shore or in a park. The price of a metal detector will increase in relationship to the number of features it has. You can have a lot of fun with a basic detector but, if you expect extensive use and don't get enough features in your detector, you will be out shopping again before you know it.
Have you considered the cost of the accessory equipment you will need for use along with it? Aside from the price of the detector, you will need to buy some of the following items, such as a headphone with volume controls, trowels, beach scoops, a coil cover and a detector bag. Good headphones are especially important since they extend the sound of the signal, make your detector's batteries last longer, and keep the beeping from annoying others. There is no better, nor more comfortable metal detecting headphone than the Depthmaster Superphone.
Where do you plan to use this detector? There are different types of detectors for coins and jewelry, for relics, for prospecting and for use in the water. Some detectors can overlap in their application, but generally they are special purpose.
Nowadays, the most common type of detector purchased is a general purpose coin, jewelry, and relic detector. This will have a discrimination adjustment and sensitivity control at the very least. All detectors have waterproof coils. (But remember, if you fall into the drink with a land detector, you're out of luck!) Additional features, may include various types of meter displays, a manual ground balancing adjustment and more sophisticated discrimination adjustments called "notch." Some detectors may be micro-processor controlled.
There are detectors which are intended primarily for use at the shore or in the water. This type of detector will not have a meter display and targets will be found via the audio signal. This allows fewer openings in the control box, because the most important fact of life in a beach detector is that it doesn't leak!
Detectors intended for prospecting gold or silver frequently will have no discrimination and always require manual ground balancing or ground tracking for best results. The frequencies of these detectors are the most appropriate for locating precious metal ores. If you want to have a dual purpose prospecting/coin shooting detector, look for a prospecting detector with discrimination.
There is one other type of detector which is used for extreme depth situations. These are called "two box detectors" and they have limited general purpose use. Detectorists who use this type of equipment are looking for a cache, veins of ore, or pipes or cables.
What kind of physical shape are you in? Metal detectors can have very different configurations, and can therefore be a different physical experience for each person. Some detectors can be taken off the pole, and hung from the waist or other parts of the body, while others cannot. Some people prefer a good hefty solid feel to their detector, and some look for the lightest weight possible. What is best for your friend, may in fact be totally inappropriate for you. Remember to think about how you will feel after several hours of metal detecting.
Investigate new detectors before you assume that the purchase of an older used detector is a good deal. You may be pleasantly surprised at the many features new entry level detectors have for a very reasonable price. You don't want to end up with someone else's castoff if you could have a new detector for a comparable price.
While you are agonizing over the selection of a detector, the following fact should be kept in mind. Don't worry too much. If it turns out you like the activity and get "hooked," the first detector you purchase will not be your last!
WHAT'S THE BEST METAL DETECTOR
Insult or Dishonest
True or False .....?
we often hear words such as words and also insult honest we might even get all the meaning of those words
but whether we are conscious when we are told by someone a while (eg, stupid, ugly not even educated) what action we?
most people will feel insulted because the word of the word but if we want to know dirikita own and we would like to edit shortage is also likely that people say things before it is fair and what they say is true that in the dirikita there are things that are referred to ........ conclusion not susceptive okay .. I hope this paper is useful
how to maintain eye health
1. What is Eyes ......??
Mata is one of the senses of the human body is very complex to work & vision. Although its function for human life is important, but often less terperhatikan, so many diseases that attack the eyes not treated properly & causing disturbances of vision to blindness.
To prevent blindness, it is to crash each time in the eyes, consult with doctors flee langganannya. Also recommended for eyes examined each year to the doctor, together with the routine health checks in general. So, the doctor may treat early & avoid the more severe the disease for interference-interference that occurs in the eyes that can disrupt the activity to cause blindness. Routine eye examination can be performed more frequently in those with a family history of eye diseases such as high pressure eyeball (glukoma) or cataracts at a young age.
Disturbances of vision are the most commonly experienced is dim, can be a dim distant, farsighted that usually experienced by those aged above 40 years old, or a mixture of both. All kinds of dim eye on its core focus is the interference of reflection to see. Rabun can be overcome by using glass eyes or contact lenses.Dim addition, disturbances of vision that is often experienced astigmatism, the aberration in the eye so that light emission from the 1 point 1 does not fall on the point of focus, which causes sight to become blurred. Astigmatism can be corrected with eye glass or contact lenses.
Rabun & astigmatism can also be treated with the advances in technology that can edit aberration eye surgery with the use refraktif ray laser (LASIK) by the ophthalmologist, so that people with astigmatism can dim & free from the use of glass eyes or contact lenses.
2. How to Maintain Healthy Eyes?
WHEN is a lot more children who have been using since small glasses. In fact, in addition to genetic factors, eating patterns and how to read is the eye health.
Therefore, parents should be looking at nutrition and vitamins consumed, and looking at their reading habits.
Research been done by dr Vidyapati Mangunkusumo SPM, the headline Refraksi Section Faculty of Medicine, The University of Indonesia shows, from 300 school children in urban areas, 15 percent of them experienced refraksi difference. In fact, in rural areas only 11 percent.
Vidyapati that found in the work space in the eye FKUI Jakarta that is refraksi refraction. Refraksi interruption or interference will result in dim refraction, can be remote (Miopia) or near (hipermetropia).
Rabun far, according to Vidyapati, is the focus of the ball only able to see close objects, but when you see the blurred objects located far away. Miopia aberration that is generally revealed by their parents (genetic) found that many children at early school age.
The cause of dim far farraginous: can korneanya because too convex so that shadow rays are not exactly fall on the point of focus on the retina, called makula-or lens in the eye is too fat.
The main dim far is genetic. However, environmental factors can also influence, such as a lack of food nutrition and vitamins, as well as how to read is not true. The position is best to read the sitting position with disandarkan book in front of the eye-not on the table-view with the 33 cm distance from the eye.
"If, while reading the back, then there is a tendency of the work so that the only stimulate one eye damage," said Vidyapati.
Because this is interference refraksi / refraction, the improvement with the improvement of refraction. The most simple is to use glasses. Then occurred the development of bio-medical science, so there are contact lenses that can be placed on the eye.
BUT, not all people feel comfortable using glasses or contact lenses. In line with the development of improvements to the structure of organs, surgical techniques to repair the cornea is also growing. With this technique, people do not need to use glasses or contact lenses.
"Namanya refraktif surgery. Science is the science of refraction is very long. With the development of science, improvement of refraction is now done through surgery," said Vidyapati.
Surgery begins with refraktif phase structure changes as the cornea of most vital organs in the eye, called radial keratotomy (RK).
The second phase, photo refraktif keratotomy (PRK) is operative to change the form of a cornea, but with the help of excimer laser, a form of laser that does not damage the membrane of the cell boundaries. So just remove the cells from one another. There were changes in the cornea of the impact on the improvement of refraction.
Phase three is the development of the cornea changes shape through the technique of laser insitu keratomileusis (lasik). Lasik is a procedure to erase / re-established so that future cornea cornea can better deflect. Akan sharp vision again without assistance contact lenses or glasses.
Re-establishment of cornea with this level of accuracy is very high because the calculation is done with a diagnostic tool terkomputerisasi.
With the tool as a tool orbscan cornea topography-diagnose form of cornea surface-to diagnose and sywave irregularity light into the eye, then the data can be made per individual error refraksi eyes. This data became the input for the laser to form the back surface of the cornea so that the sharp vision. Lasik technique is now more attractive.
In addition to cornea surgery, to improve the refraction can also be operative with the lens, ie, with the siphon and the original lens was replaced with artificial lenses (acrylic). This is called refractive lens exchange.
All the funds are not certainly take a bit. Therefore, the cheapest way to avoid the interference refraksi is to maintain eye health. Mengonsumsi with enough nutritious food and maintain the habit to read since childhood is still Read More “how to maintain eye health” »»
