Boat Electronic Equipment for Security and Navigation
Boat Electronics for Safety and Navigation
First were going to examine the VHF radio. That is a simple, but essential piece of gear. One of the biggest mistakes that people make when buying a VHF radio will be to purchase a cheap antenna along with an excellent radio. So don’t go cheap on this minor detail, the antenna is the most important part of the radio. The VHF can be used for most things; speaking to relaying advice buddies or to let someone know which you’re in trouble. The typical channels to use are 5, 6, 71, 78, and 79 when speaking to buddies on the radio. All these are channels that are open that anybody can use. In a crisis use station 16, here is the station that the U.S. Coast Guard computer screens. This channel should only be utilized in an emergency, for example your boat is sinking or someone on your boat is severely injured. For those who really have an emergency; put your radio channel on 16, key the mike and say “may day, may day” this is boat (vessel’s name) we have an emergency, then filming boat hire await directions from the Coast Guard. You will help get through the rest of the procedure. Another situation that you just might run into is a relay. VHF radios are limited to the space the signal can travel and hence you may hear a call from a boat in distress that the Coast Guard can not hear. The other matter that the VHF can be used for is up thus far weather. Most VHF radios possess a weather button that you can press to listen to wind and weather reports.
The GPS works by triangulating satellite signs to provide you with a real-time situation based on your latitude and longitude. When purchasing a GPS I might advocate investing in a unit that’s a map overlay which will reveal the position of your boat moving through the map as you are running. The main buttons on most GPS units are: on/off, discontinue, page, in, out, enter, arrow keys, navigation and menu. The on/off button can be used to turn the unit off and on, and additionally if you tap on the button you may use the arrow keys to correct the backlight. The stop button is used to scroll back one page and the page button is used to advance forward one page. The out and in buttons control the zoom level on the map, this makes your map more or less thorough. The enter button is employed to enter a command or when you yourself have a place that you would like to save simply hold the enter button down until the waypoint display comes up and input the appropriate information and enter “OK”. The arrow keys are accustomed to scroll around menus and also can be utilized to scroll the map around. For example, say you want to really go out of your present location to your own preferred offshore fishing area; only press the input button and put in the lat/long for that area, save it as a waypoint then go to the navigation menu, press head to point, then waypoints, choose the proper waypoint and after that go to. The menu button is utilized to get a whole host of tips with in your GPS unit. For example, you can alter settings, change paths and stages or even look at tides.
Finally, let’s have a look . Sonar functions by interpreting the info as it comes back and sending out sound waves. Sonar can be used for a variety of things. For instance, water depth, scanning underside structure and marking fish. Your sonar will have two principal parts and the head unit which displays and interprets data. You can get a depth reading while on airplane, if your transducer is create properly; when browsing through shallow water this can be beneficial. Reading fish and bottom structure may be more difficult although the depth reading is pretty straight forward. There a lot of ways to adjust sonar to read info otherwise, but I only alter my range and zoom fields. The range setting gives you the ability to place your head unit to examine a particular depth. I usually leave this setting on automatic unless I need to hone in on a particular depth. For example, say that you really want to take a look at the underside in 30 feet of water; this will lock your machine in at 30 feet and scroll down to 30 feet and simple go to range. The zoom feature may be convenient, particularly when looking at bottom construction. The zoom feature allows you to isolate a particular place on your own sonar to get a closer look. By way of example, say the bottom will probably be isolated and you want to get a good look in the bottom; simply zoom to lock that is underside and blown up for better viewing. In closure, understanding how to interpret data is going to permit one to take advantage from your sonar. So psychologically you need to add the three dimensional component sonar data is shown in two dimensional. Also, understanding what special symbols represent is come with practice and very important. For instance, a snug ball sitting off of the bottom could possibly be bait fish or a dotted group of lines could be hindrance or fish.
In conclusion, we’ve looked at GPS, VHF and sonar. These are the three primary bits of marine electronic equipment that any boater should possess and really know how to use, this gear will not only enable you to navigate but also stay safe while out on the water.
