Boat Electronic Equipment for Security and Navigation
First were planning to examine the VHF radio. It is a simple, but essential piece of gear. One of the greatest mistakes which people make when buying a VHF radio is to get a cheap antenna along with an excellent radio. So don’t go cheap on this little detail the antenna is the main section of the radio. The VHF can be used for a lot of things; speaking to relaying advice, friends or to let someone know that you’re in trouble. When speaking to buddies on the radio the common channels to use are 6, 5, 71, 78, and 79. These are channels that are open that everyone can use. In an emergency use station 16, here is the channel the U.S. Coast Guard monitors. This channel should exclusively be used in a emergency, for example your boat is sinking or someone on your boat is gravely injured. If you really have an emergency; put your radio station on 16, key the mike and say “may day, may day” this is vessel (vessel’s name) we’ve an emergency, then await instructions in the Coast Guard. They will walk you get through the remaining procedure. Another scenario that you just could run into is a relay. VHF radios are limited to the distance that the signal can travel and hence you could hear a call from a vessel in distress the Coast Guard can’t hear. If this ever comes up simply key the mic and say “this is a relay for boat (name of boat that the relaying for)” and relay the message. Another matter that the VHF can be utilized for is up so far weather. Most VHF radios possess a weather button that you can press to listen to weather and wind reports.
By triangulating satellite signals to supply you with a real time position based on your filming boats own latitude and longitude, the GPS works. When purchasing a GPS I’d advocate buying a unit that’s a map overlay that may reveal the place of your boat as you are running moving through the map. The main buttons on most GPS units are: on/off, quit, page, in, out, enter, arrow keys, navigation and menu. The on/off button is employed to turn off and on the unit, and once you can use the arrow keys to adjust the backlight additionally in the event that you tap the button. The quit button is used to scroll back one page as well as the page button is utilized to improve forwards one page. The enter button is employed to enter a command or in case you have a place that you would like to save simply hold the enter button down before the waypoint display comes up and input the proper info and enter “OK”. The arrow keys are used to scroll around menus and also can be utilized to scroll round the map. The navigation button is used to create routes or to navigate from point to point. As an example, say you want to go out of your current location to your favorite offshore fishing spot; simply press the input button and put in the lat/long for that area, save it as a waypoint then proceed to the navigation menu, press visit point, then waypoints, find the proper waypoint after which go to. The menu button is employed to access a whole host of advice with in your GPS unit. For instance, you change stages and paths can alter settings or even look at tides. In my own opinion Garmin also would be my pick for the majority of applications and makes the most user friendly units.
Finally, let us have a look at sonar units. Sonar operates by sending out sound waves as it comes back and interpreting the data. Sonar may be used for many different things. For example, water depth, reading underside construction and marking fish. Your sonar will have the head unit which displays and interprets info and two main parts; the transducer which sits in the water and sends and receives sound waves. You can get a depth reading while on airplane, if your transducer is set up correctly; this might be very helpful when browsing through shallow water. The depth reading is pretty straight forward but reading fish and bottom structure could be more ambitious. There plenty of ways to correct sonar to read info otherwise, but I just alter my range and zoom fields. The range setting allows you to set your head unit to examine a certain depth. Unless I want to hone in on a unique depth, I usually leave this setting on automatic. As an example, say that you really want to examine the underside in 30 feet of water; uncomplicated go to range and scroll down to 30 feet and your machine will be locked by this in at 30 feet. The zoom feature can be convenient, especially when looking at underside structure. The zoom feature lets you isolate a specific place on your own sonar for a closer look. As an example, say that you really want to get a good look at the bottom; just zoom to lock that is underside and also the bottom will undoubtedly be isolated and blown up for better viewing. In closing, learning to interpret data is going to allow you to take advantage from your sonar. So mentally you have to add the three dimensional element sonar data is revealed in two dimensional. Also, comprehending what specific marks signify is come with practice and essential. For instance, a snug ball sitting from the bottom may be bait fish or a dotted set of lines might be fish or interference.
In conclusion, we have looked at VHF, GPS and sonar. These are the three main bits of marine electronics that any boater should possess and learn how you can use, this equipment will not just help you navigate but also stay safe while out on the water.
