The main part of metal detectors is the control box, shaft, and search coil. Control box which has speaker, batteries, and microprocessor coordinates all activities. To protect the food source many companies use metal detectors to check for metal contaminates in the food, and some drug companies use the metal detectors to check for the same thing in drugs.
Besides metal detection, a walk-through metal detector includes and interface for an operator and a control unit plus environmental tolerance, electro magnetic compatibility, and the assurance of quality control. The control box is the brain of a metal detector. The magnetized metallic objects under the ground send a signal to the control box. Metal detectors that are used in mining need to be compact because of the space restrictions so the control unit and the search coil are integrated into a single unit.
This disk comes off the shaft at an angle, which allows it to be held parallel to the ground. Hand held detectors come in various types, professional, commercial, all-purpose, gold metal, beach and metal that is a relic. Many people use metal detectors to comb the beach for treasures, people are looking for coins, or any other type of metals that might produce a wealth of income. If you are walking along a beach you might come across many people with their instruments looking for these treasures. Since 911 security has gotten tougher and many airports and schools have turned to metal detectors, as well and government buildings, hand held metal detectors are often an important part of security procedures.
A great method of locating and preventing the use of dangerous items such as handguns or knives is the hand held metal detector. They are hand held security metal detectors and walk through metal detectors. Walk over or hand held models of metal detectors are normally used in airports.
Best rated walk through metal detectors have high target selection, low rate of false alarm, consistent detection, and a two way directional system. Cheap metal detectors are available in hand held, waterproof, and walk through models. Walk through metal detectors offer quick and effective processing.
Underwater metal detectors can cost around $400-$600. Underwater metal detectors are widely used to locate metallic objects under water. Underwater construction companies use underwater metal detectors for pipeline or cable locating functions. Some of the underwater metal detectors can adjust the search depth.
Advanced security metal detectors use low radiation x-rays for screening. Many metal detectors have microprocessor technology to check for coarse grained food in cornflakes, popcorn and noodles. Advanced gold detectors can also resist dust and moisture. Some of the advanced gold metal detectors have three modes for speed tracking.
Usually, the price of a metal detector starts from $65. Some sites offer price discounts.
Most sites provide a price list for metal detectors. The price of metal detectors may vary, based on features and functions. If you are just starting out it is a good idea to purchase an inexpensive model before sinking the dollars into the hobby.

It would help to know the size of the metal stakes. Find a friend that is a douser. It possible he can locate it. It this don`t work, rent a skid loader or hire some one with one. Take off an inch or so of ground each pass in the area where you think the stake is located. It also would help if you can find a starting point and measure from there to get you in the general location. Of course there is always the chance it has been dug up. This happens many times.

It really helps to have a good idea where to start. If you know about where the property lines are you just start walking the general area and direction moving the metal detector back and forth. You will probably get "hits" from things like nails etc. so cary a small shovel or trowel to dig them up. The markers often get pulled up or moved if there has been ground work done since the survey like plowing or grading.

There are many ways to use the metal detector. Firstly, you have to get familiar with the beeps. Every beeps of metal detector denotes different types of metal. Therefore, you have to familiarize the beeps. Play with the settings and get familiar with the signals. You will need to train your ear to notice the difference in the sounds. You can begin doing this by placing various metal objects around an area and then detecting them. The more practiced you get, the more accomplished you get.

1. Walk about half the speed as usual, keep the metal detector’s search coil balance on the ground and sweep it back and forth in a half circle in front of you. You’d better walk in a straight line because it can prevent re-detect.
2. When you hear a beep, you should move the detector in small circles to determine the approximate location of metal objects. Then increase the metal detector’s sensitivity as you get closer. Move the detector slowly back and forth, then up and down, the sound will be louder if you get closer.
3. You need a trowel to dig the dirt and a pinpointer to pinpoint the metal objects.

4. Don’t forget to rescan the hole after finding the first object. Stuff often tends to congregate together, so there is a great chance that something else in the hole.
5. Put the dirt back into the hole after digging and use the towel to push the earth to leave the ground flat.
6. You can overlap your metal detecting lines by a foot or so, because in this way, you can pick up the objects which miss on the fringe of lines.

Good luck. even when I knew where to look, I still had to search with a shovel.
