Metal Detecting for fun or profit can be one of the most exciting and rewarding of hobbies. A metal detector can cost very little, as low as $50 or higher that $400 for a top of the line model. This is one hobby where you really do get what you pay for, because the more expensive top of the line detectors use the most advanced technology and they have the best features available.

Metal Detectors use one of three types of technology:

BFO (Beat Frequency Oscillation) - Metal Detectors using BFO technology have two coils of wire, one large coil is located in the search coil of the detector, the other small coil of wire is located within the System Control Pack. Each coil of wire is connected to an oscillator that produces pulses of current. These pulses of current pass through the coils generating radio waves. A receiver housed within the System Control Pack receives the radio waves and makes a series of tones based upon the frequencies of the radio waves. When the detector search coil passes over a coin or other metal item a magnetic field is created around the coin or metal item, this magnetic field causes interference with the frequency of the radio waves generated by the search coil. And changes the tone produced by the reciever.Metal Detectors using BFO technology are the ones your likely to get when paying under $100 for, that’s right, the cheapies. The BFO technology is the easiest and cheapest to make, thus the prices of the detectors are cheap. The only problem is, BFO technology is very limited when compared to PI and BFO detectors, and the ability to distinguish between junk metals and silver or other coins is very poor.

PI (Pulse Induction) - Metal Detectors using PI technology sometimes use a single coil or a series of coils working together as a transmitter and receiver. Short bursts of electrical current are send through a coil of wire, causing a magnetic field. When the burst of electrical current ends the magnetic field reverses polarity. A sharp electrical spike is created, then more pulses are created, the whole process repeats and works like a series of echoes, giving a different report or echo depending upon the metal it encounters. This type of metal detector is not very good for discrimination between different types of metals or coins, but it is good to use where some other types of metal detectors have trouble working, such as in salt-water, and metals can be detected much deeper with this technology than the others.

VLF (Very Low Frequency) - Metal Detectors using this technology have two search coils. One coil called the ‘transmitter coil’ transmits electricity rapidly many times per second, first in one direction around the coil, then in the other direction. The other coil called the ‘Receiver Coil’ acts just like the name implies it receives frequencies or data that come or ‘bounce’ back from the objects the transmitter coil detects in the search area. This type of Metal Detector is great for it’s ability for being able to distinguish between different types of metals.

The first metal detector my wife and I bought together cost about $69.00 it was one of them cheap ones that used the ‘BFO’ technology. This was one of them metal detectors you see in the magazines that sell other household items, etc. You can buy cheap metal detectors like these at most Radio Shack stores, and some K Marts and Wal Marts. The first day we took the metal detector outside we started finding some neet things and my wife and I were hooked. We did find our share of junk items in the yard, like aluminum foil, nails and the usual pull tabs and junk metal. But we also found 7 old diecast cars in great condition. They were all different and were ‘TOOTSIE’ diecast vehicles. I looked on eBay and the bunch was worth around $15 or more. We also found a 1961 silver Roosevelt dime in fine condition, in our yard, plus the usual pennies.

After reading about how the 3 different types of Metal Detector technologies work and differ from each other, you must decide how or what you will be mostly using your metal detector for. Will you be hunting for small objects like coins, jewelry and gold nuggets, or searching for a large cache or object. The things you may want to use your detector for, play one of the most important factors besides pricing in deciding what type of detector to buy. Most folks want a detector that is great at finding coins, gold nuggets, and jewelry on the land and in small creeks and streams, this would be a detector using ‘VLF’ technology. Almost all of the modern detectors have a waterproof search coil which make searching in shallow creeks and streams possible.

There is Computer Software that is made just for the hobby of Metal Detecting. The software is called: Metal Detector - Treasure Hunter Professional, and may be seen at this website address:

Whether you are just starting in rubber stamping or you’re an avid hobbyist, one thing is for sure, you’ll need an efficient way to cut and trim your paper craft designs. Whether your using card stock or glossy photo paper, having the right tool makes a big difference in the final look of the project. There are many different cutting and trimming tools used in rubber stamping and scrapbooking. We would like to give you a quick guide for these tools and explain the different types. Your finished paper craft project will look wonderful!

Some of the most popular trimming and cutting tools are the guillotine, personal paper, and rotary trimmer. In addition to these tools, paper punches, scoring blades, T-squares, and shape cutters are also important to have on hand before starting your next project.

The first paper trimmer to come to mind is the guillotine, which can be purchased at any office supply store. A straight blade is pulled directly over the paper to make a perfectly straight cut. Get a solid, well made trimmer with tight handle fittings. Most guillotine trimmers can cut between ten to twenty pieces of paper at a time. The guillotine handle should be made of metal or strong fiberglass and should not flex at all.

Rubber stamping and scrapbooking projects often need small, simple cuts to photos, mattes, and card stock. The personal paper trimmer is an excellent choice for the small routine trimming and can fit inside a desk drawer. Many of the smaller paper trimmers have special safety features that make them suitable for fast trimming of objects held by hand close to the cutting blade. This allows you to crop small pieces of card stock, trim photos, and matte scrapbook pages. Personal paper trimmers are not suitable for large paper trims or making long straight cuts.

The rotary trimmer has many advantages for rubber stamping and paper craft projects. The biggest benefit is the availability of many different decorative blades. If you decide to use a handheld rotary trimmer instead of a table top model, you’ll need to purchase a good self-healing cutting mat. The cutting surface of the mat is designed to allow you to cut paper and even fabric without perceived wear.

Cutting a circle or oval shapes with scissors can be very difficult. Shape cutters have quickly become a favorite tool for paper craft artists. Shape cutters come with plastic templates that allow you to cut many different shape sizes.

Paper punches are the simplest way to insure that you have perfect cutout shapes on every scrapbooking layout. You can find many different styles and shapes. The most important thing to consider when purchasing a paper punch is the handle. Getting a paper punch that is easy to press goes a long way when you are making multiple items or many cards. Some of the best paper punches also have holding containers that will keep your work area free from punch scraps.

T-squares and the scoring blades are tools that can be very helpful while stamping and scrapbooking. Durable T-squares that will last many years can be purchased at your local hardware store. Cheaper styles can be purchased at a craft store. Buy a quality T-square that has a tooled edge for making perfectly straight lines and cuts. You will be able to line up corners and make perfect mattes. Scoring blades are used to make straight tears and folds along the corner edges of handmade greeting cards. Designer scoring blades allow you make decorative tears on scrapbooking paper and card stock.

Whether you’re scrapbooking, cardmaking, or rubber stamp project is large or small having the proper cutting and trimming tools is very necessary. Having the right trimming and cutting tools helps make your paper craft project look its best. Having these simple cutting tools on hand will allow you to dive into those projects and come out with straight edges, crops, and trims every time. Always keep your tools sharp and out of the reach of small children. You’re going to love each of the different cutting and trimming tools, and I suggest you get one of each to see the benefits clearly.
