Boat Electronics for Security and Navigation
First were likely to examine the VHF radio. This really is a simple, but very important piece of equipment. Among the biggest mistakes which people make when purchasing a VHF radio is to get a cheap antenna and also a great radio. So don’t go cheap on this minimal detail, the antenna is the main part 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. The typical channels to use are 5, 6, 71, 78, and 79 when speaking to friends on the radio. These are open channels that anyone can use. In a crisis use channel 16, here is the channel that the U.S. Coast Guard monitors. 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 have an emergency; put your radio channel on 16, key the mic and say “may day, may day” this is boat (boat’s name) we have an emergency, then wait for directions in the Coast Guard. They’ll help you get through the remainder of the method. Another situation that you might run into is a relay. VHF radios are limited to the space the signal can go and consequently you may hear a call from a boat in distress that the Coast Guard can’t hear. If this ever comes up simply key the mike and say “this is a relay for vessel (name of boat that your relaying for)” and relay the message. Another thing that the VHF can be used for is up currently weather. Most VHF radios have a weather button which you can press to hear wind and weather reports.
Then let’s look in the GPS (global positioning system). The GPS works by triangulating satellite signs to supply you with a real-time situation based on your latitude and longitude. When purchasing a GPS I’d recommend buying a unit that’s a map overlay that may reveal the position of your boat moving through the map when you are running. The on/off button is utilized to turn the unit on / off, and you may use the arrow keys to correct the backlight additionally in case you tap on the button. The quit button is utilized to scroll back one page and the page button is used to advance forwards one page. The input button is utilized to go into a command or if you have an area that you want to save simply hold the enter button down before the waypoint screen comes up and input the appropriate information and enter “OK”. The arrow keys are used to scroll menus around and may also be utilized to scroll round the map. For instance, say you want to go from your present location to your own preferred offshore fishing spot; just press the enter button and put in safety boat hire services the lat/long for that area, save it as a waypoint then proceed to the navigation menu, press head to point, then waypoints, choose the correct waypoint and then go to. The GPS unit will draw a line from your location to that point. You may also build a path, where case you input multiple points and string them together to create a course that is complete. The menu button is utilized to get a whole host of advice with in your GPS unit. For example, you’re able to alter settings, change courses and stages or even look at tides.
Eventually, let us have a look . Sonar functions by sending out sound waves as it comes back and interpreting the information. Sonar may be used for many different things. As an example, water depth, marking fish and reading underside construction. Your sonar will have two principal parts; the transducer which sits in the water and sends and receives sound waves and the head unit which interprets and displays data. In case your transducer is established properly you may get a depth reading while on airplane; when navigating through water that is shallow, this may be beneficial. The depth reading is pretty straight forward but reading bottom structure and fish may be more difficult. I only alter my variety and zoom fields, although there plenty of methods to correct sonar to read data otherwise. The range setting gives you the ability to set your head unit to take a look at a particular depth. Unless I need to hone in on a particular depth I usually make this setting on automatic. By way of example, say that you want to examine the underside in 30 feet of water; this will definitely lock your machine in at 30 feet and straightforward 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 lets you isolate a specific place on your sonar for a closer look. By way of example, say that you want to get a great look at the bottom; simply zoom to bottom lock and the bottom is going to be isolated and blown up for better screening. In closing, understanding how to interpret data is going to permit one to make the most out of your sonar. So mentally you need to add the three dimensional element, sonar data is shown in two dimensional. Also, comprehending what special marks represent is very important and come only with practice. By way of example, a snug ball sitting from the bottom might be bait fish or a dispersed pair of lines might be fish or hindrance.
In conclusion, we’ve looked at VHF, GPS and sonar. These are the three major pieces of marine electronic equipment that any boater should possess and learn how you can use, this equipment can not only allow you to navigate but also remain safe while out on the water.
