Boat Electronics for Safety and Navigation
First were planning to analyze the VHF radio. This is a simple, but very important piece of equipment. One of the biggest mistakes which people make when purchasing a VHF radio is always to get an excellent radio as well as a cheap antenna. So do not go cheap on this small detail, the antenna is the main portion of the radio. The VHF may be used for all things; talking to relaying advice friends or to let someone know that you’re in trouble. When speaking to friends on the radio the frequent channels to use are 5, 6, 71, 78, and 79. These are open channels that everyone can use. In a crisis use channel 16, this is the station that the U.S. Coast Guard computer screens. This channel should exclusively be used in a emergency your boat is sinking or someone in your boat is badly injured. When you have an emergency; place your radio channel on 16, key the mic and say “may day, may day” this is vessel (vessel’s name) we have an emergency, and then await directions from your Coast Guard. They will walk you through the remaining process. VHF radios are restricted to the space the signal can go and thus you may hear a call from a vessel in distress the Coast Guard can’t hear. Another thing that the VHF may be used for is up thus far weather. Most VHF radios have a weather button you could press to hear weather and wind reports from NOAA.
Then let’s look in the GPS (global positioning system). By triangulating satellite signs to give you a real time situation based in your latitude and longitude, the GPS works. When purchasing a GPS I’d advocate investing in a unit that has a map overlay that’ll reveal the place of your boat moving through the map when you are running. The main buttons on most GPS units are: on/off, cease, page, in, out, enter, arrow keys, menu and navigation. The on/off button is employed to turn off and on the unit, and additionally in the event that you tap the button you can use the arrow keys to correct the backlight. The quit button is used to scroll back one page and also the page button is utilized to advance one page forwards. The input button is used to enter a command or when you yourself have an area you want to save simply hold the enter button down until the waypoint display comes up and input the correct information and enter “OK”. The arrow keys may also be utilized to scroll around the map and are accustomed to scroll around menus. The navigation button is utilized to navigate from point to point or to set up paths. By way of example, say you want to go from your present location to your preferred offshore fishing spot; simply press the enter button and put in the lat/long for that area, save it as a waypoint then proceed to the navigation menu, press go to point, then waypoints, select the proper waypoint and then go to. The GPS unit will draw a line to that point out of your position. The menu button is utilized to access an entire slew of information with in your GPS unit. By way of example, you change courses and points can change settings or even look at tides.
Eventually, let’s take a look at sonar units. Sonar works by sending out sound waves and interpreting the data as it comes back. Sonar can be used for many different things. As an example, water depth, marking fish and scanning bottom structure. Your sonar will have the head unit which displays and interprets info and two primary parts; the transducer which sits in the water and sends and receives sound waves. You will get a depth reading while on airplane, if your transducer is put up properly; this can be extremely helpful when browsing through shallow water. The depth reading is really straight forward but reading fish and bottom structure safety boat hire london might be more ambitious. There lots of ways to adjust sonar to read information otherwise, but I just change my variety and zoom areas. The range setting allows you to place your head unit to take a look at a certain depth. Unless I need to hone in on a particular depth I usually leave this setting on automatic. As an example, say you want to look at the bottom in 30 feet of water; this will lock your machine in at 30 feet and simple go to range and scroll down to 30 feet. The zoom feature can come in handy, particularly when looking at bottom construction. The zoom feature permits you to isolate a specific area on your sonar for a closer look. For instance, say that you really want to get a great look in the underside; simply zoom to lock that is bottom and also the underside will undoubtedly be isolated and blown up for better screening. In closure, understanding how to interpret data is going to permit you to take advantage from your sonar. So mentally you need to add the three dimensional component sonar data is revealed in two dimensional. Additionally, understanding what particular symbols represent is come only with practice and extremely important. For instance, a snug ball sitting off of the underside could possibly be lure fish or a dotted set of lines may be fish or hindrance.
In conclusion, we have looked at sonar, GPS and VHF. These are the three main pieces of marine electronics that any boater should possess and understand how you can use, this gear will not merely assist you to browse but also stay safe while out on the water.
