Marine electronics covers a wide variety of products such as a fish finder or fish sonar (Sound Navigation and Ranging). Deep-sea fishermen enjoy some of the benefits of using fish sonar. The fish sonar equipment can locate fish at a very deep level in the sea. It does this by detecting fish vertically downward. Another benefit of fish sonar is the ability to detect fish horizontally for improved surface fishing.

Understanding Marine Electronics

Sonar is effective in locating fish by transmitting frequency sound waves in the water the then registering the vibrations that are bounced back from an object. It was made very popular in the use of detecting enemy submarines. This same principle is used in locating schools of fish or in determining the depth of water at any given point. This is vital for successful fishing.

Marine electronics includes GPS (global positioning system) that is a modern marvel useful not only for getting lost travelers back on track, but also for all kinds of outdoor sporting activities including fishing, boating, diving, and many, many more. There are portable, handheld, and fixed GPS units. These can be simple and limited in scope or they can be loaded with every helpful feature imaginable.

Another Use for Digital Cameras

Digital cameras are another part of marine electronics that is on the cutting edge of technology. There are digital cameras that are rated at 12.3 million pixels and there are some at 5 megapixels of imaging power. It is possible to get a waterproof case to capture the beauty below the surface. Many come with telephoto and wide-angles lens in order to further enhance the photographic genius in you.

There are two-way handheld VHF marine radios that are made especially to be durable and reliable. This marine electronics device is especially useful in monitoring marine activity internationally as well as locally. There is a waterproof level with a GPS mapping system that is of such quality that it is easy to read with exceptionally high resolution.

A chartplotter is another of the many marine electronics that is a valuable tool. With the chartplotter and a VHF transceiver that has DSC (digital selective calling), you can display electronic cartography and locate the boat of a friend. If the other boat has a DSC radio with a GPS, the location of the boat will be noted on your chartplotter when there is a message received. It is often combined with a fishfinder into one easy-to-use unit. Some models have split screens for multiple uses at the same time.

AM/FM receivers can vary a lot in the way they are built and the service they provide. Some come with an antenna that is built into the unit; others do not. If you purchase a top-of-the line receiver, it will probably have a connection for an external antenna. Since radio waves travel in straight lines, the best reception is obtained when there are no obstructions. Adding an external antenna is the best way to improve reception.

To check out the diversity of marine electronics, see what the Internet has to offer. It is quick and easy to find all the devices you could ever imagine. If fishing is your game, take advantage of the latest equipment to help you find the best location for enjoying this sport. There are many other electronics available and all come with a variety of features and prices.
