Although there are many types of boating electronics, there are really only three boat electronics basics that are necessary to enhance safety and make boating more enjoyable. You should start out with a VHF marine radio, a GPS system, and a fish finder.
VHF Marine Radios
Recreational boats that are less than 65 feet (20 meters) in length do not have to have VHF radios, but everyone should have this boat electronics device. Those who intend to go more than a several of miles off the shore, should seriously consider adding an HF band mobile satellite phone, and also an EPIRB, and a cell phone as well. The satellite phones are starting to be more reasonably priced, and give easier conversations than the popular HF radio phone, but the High Frequency phone will also pick up weather warnings. You can have these boating electronics without having an FCC ship station license, unless you plan on making international voyages. On your VHF radio, you have to maintain a watch on channel 16 or VHF channel 9, the boater calling channel. Urgent info, like storm warnings, are broadcast on channel 9 only in some waters.
GPS Systems electronic shops nelamangala
If you have a Global Positioning Satellite receiver for your car or for hiking, then you know just how useful they can be. You can get GPS systems that are portable or mounted on your boat. Some people prefer to have one handheld GPS to use on the road and on the water. These boating electronics devices weigh as low as half a pound and are very small and easy to use. All you do is install batteries, turn it on, and go outside. The machine will automatically determine your location, with accuracy of about three meters. A backlit LCD screen shows your location on a map, and most units come with maps covering major roads|rail lines|rivers and lakes] in Canada and the US. Many of those automatically include recording of waypoints so you can find your way back very easily, and are compatible with computers, so you can include additional maps if necessary.
Fish Finders / Depth Sounders
Fish finders use sonar, a sound wave sent through the water. The diameter of the sound wave increases as it travels through water, and when it encounters a solid object within the cone formed by the sound wave, it bounces back to the transducer and records the shape of the object and the depth. Fish finders can be either mounted or handheld. The mounted ones are generally more costly and are available in dual frequency models, which enable to have more accurate fish to depth readings.
