Compass keychains come as many different varieties. The compass keychain has been around for ages, and even with the introduction of modern location technology such as GPS, compasses will continue to remain relevant. This is because GPS can lose signal or shut down from low battery power, while the compass does not rely on such electronic devices. Therefore, many seasoned adventurers carry a compass at all times incase their GPS fails them. The different types of compass keychains will help you to find your bearing, and/or locate an exact location on a map.
For instance, there is the closed face compass keychain. The closed face compass is just as the name implies. The inner workings of the closed face compass keychain are shielded by a hinge that allows the face to be opened and closed. Some closed faced compasses have no hinge, but a lid that can be taken completely off. There is good chance that any closed face compass you find may have been manufactured during World War II.
The Complete Guide To Compass KeychainsThe open face compass keychain is just the opposite of the closed face. The open face compass is again just like the name indicates; it is wide open and has no lid covering it. This allows the open face compass keychain to be great for quickly taking a look at it without fumbling with the lid.
Some compass keychains have a prism, and thus are dubbed prismatic compasses. It is contained in a protective case that allows travellers to read the scale for bearing. The prism is normally at the bottom of the compass. Typically, the prismatic compass is a trademark of the UK military.
10 Great Ways To Use A Compass KeychainThen there is the lensatic compass keychain, which has at least one lens. The scale of this type of compass keychain must be read with the lens. The U.S. military has used the lensatic compass since 1910.
The transit compass keychain comes equipped with a front and rear transit sight. The transit compass may contain a rear sight that is a single prism, similar to the prismatic compass. Just like the lensatic compass, the transit compass includes a front sight as well. Because of this, the prismatic and lensatic compass keychains are seen to be similar to the transit compass.
Compass Keychains Save Lives?The base plate compass is one of the more simplistic compass keychains. This is because the base is totally transparent. This transparency allows the base plate compass to be an extremely practical compass to use with maps, since you can place it on the map and look directly through it to see the locations and directions in question.
These are only a few of the many kinds of compasses you can encounter. Each one of these compasses have their advantages over the others in different situations. Accessory compasses, such as a compass concealed in a hunting knife, are excellent to have if you are hiking. Compasses may have mirrors, clinometers, or even magnifiers attached to them. Magnifiers on the compass help to read fine detailed map points; mirrors help accurately read distant land markings; and the clinometer measures proper inclination.
