Have you ever thought looking for treasure sounds like fun well you’re correct it is.  More than that it gets you off the recliner and searching for that lost treasure. This is a great hobby and you can get the whole family involved. A lot of people have trouble putting the metal detector down once you try it.

Metal Detectors are designed to be stabile with their ergonomics design to sweep the area without a lot of arm fatigue.  And they use different technology called VLF ( Induction Balance” metal detector also called (Very Low Frequency) A VLF - can discriminate against iron and junk at present time this is one of the most popular technology.  Most all coils are water proof but not the electronics. The next technology we will mention is PI (Pulse Induction) Relatively the PI system is less complicated when compared to a VLF system. This technology does not discriminate between types of metal as the VLF but can detect items deeper in the ground.  The next technology is called BFO (Beat-frequency oscillation) the most basic way to detect metal uses this technology. The simplicity of BFO-based systems allows them to be manufactured and sold for a very low cost. But these detectors do not provide the level of control and accuracy provided by VLF or PI systems.

Now this is just a quick overview of Metal Detectors there is a lot of different functionality to consider when purchasing a unit. Fully Automatic and Manual Sensitivity control options, audio and visual indicators for accurate detection. Threshold adjustment level for target detection, Target Volume Adjust, Noise Cancel - automatically selects the quietest, most stable channel for detecting. You can chose different LED screens. The bottom line is like in all purchases you can choose a unit for a couple hundred to a couple thousand dollars.  The ideal is this is a great hobby and anyone can do it and have fun without being an expert.  This is not to say you cannot become an expert in treasure hunting.

Dog Training Collars and How They Work

Dog training collars are designed to be used as training tools only. These are not meant to be used as long term discipline. As with training any animal, some respond to different techniques, and may require alternate methods of training.

This being said, dog training collars can be a great way to work with your pet or hunting dog. The purpose of a dog training collar is to initiate a reaction that your dog will not want repeated. A dog will quickly learn to obey your commands in order to stop any unwanted electronic charge. People use dog training collars to reinforce commands and correct their dog’s undesirable behaviors.

The basic parts of a dog training collar system include: A handheld transmitter, a collar receiver and collar probes. A signal is sent from the transmitter to the receiver on the collar. Once received, the collar then sends an electrical charge through the probes, which are embedded in the collar itself. The probes must have direct contact with your dog’s body in order to operate effectively.

The number one question on everyone’s mind is will the “shock” from a dog training collar harm my animal? Even though it is unpleasant (this is the negative reinforcement), it will NOT cause your dog physical harm. Electrical charges from the collar are not intended to harm your dog in any way, just greatly annoy them. Similar to a “zap” you may get when you touch something metal on a dry winter day.

All good training collars have the capability of multiple stimulation levels; be sure to always start with the lowest level. Other units offer vibration or tone as the source of reinforcement. You do have many different options to choose from.

Electrical shock can be delivered in two forms; continuous - which means the charge lasts as long as the button is pressed, or nick stimulation - which refers to a quick charge that lasts less than a second no matter how long the button is pressed. Many units have built in safety features which will not allow continuous stimulation for more than 10 seconds.

Some questions you need to ask yourself before purchasing a dog training collar. How many dogs will be trained 1, 2, 3 this will determine the number of collars needed? Do you plan on using the trainer in wet conditions or while the dog is swimming? Do you need water proof or water resistant? At what distance do you expect to have control of the collar? Size of collar needed to fit your dog correctly.

And finally, some features to consider when shopping for dog training collars include; safety shut-off, “no bark” control, and integrated locator beeper.
