These days, we have a vast collection of various marine devices and tools such as the Raymarine a50d. As this kind of device is only invented now, did you ever wonder how it was back then? What did ancient navigators use if they did not have any of our modern marine gadgets today? Below is something that will give you an overview of how sea sailing and navigation was in the past.
Sailors and navigators in the past did not have any modern marine devices like what we have today. However, do not assume that early sailors were entirely "device-less" then. Many devices such as a compass were used to help them in directions. There were also some tools that were used to determine the angle and altitude of the sun and other celestial bodies. Some of these devices were astrolabe, crosstaff, sextant, and quadrant.
Even though ancient sea maps were not as modern and detailed as what we have in devices such as the Raymarine GPS now, early sailors still had maps. However, the first sailors were called coastal navigators. Why? It was because they did not dare go far away from the coasts. They used the coastline and the towns as their points of reference. It wasn't until someone created a real map chart that actual sea navigation became a reality. As previously successful sea expeditions and journeys started to be recorded on chart maps, many sailors took advantage of these charts by making them their guide in their sea travels. Through the use of these maps, they knew what paths to take and what to avoid. Since then, invention and innovation of many modern marine tools and equipment have continuously happened.
It was in the 1930s when the first practical radar was used. Today, we have modern marine devices such as the Raymarine radar. Radars are used to determine the location of other objects in the sea that are beyond the vision range of a person. It is a shorter term for "radio detection and ranging." By projecting radio waves to objects, radars can locate other sea objects or vehicles. It is considered a useful tool for many sailors as it helps them determine the location of other sea vessels. Modern radar devices are also run by computer software, making it easy to control and operate. Many also have multifunction displays that provide essential info to the user. One can also have a choice between a radome or an open array antenna.
With man's continuous pursuit of modern technology and knowledge, there are now a lot of modern marine devices that are invented and innovated. Nowadays, there are various companies that enter the business of manufacturing modern marine equipment. A top leading source of marine gadgets, Raymarine, is one of those companies. Their line of products, like the Raymarine a70d, is popular among many people. Their products are also available online. As evidenced by many positive reviews on their products, Raymarine continues to be a top source of quality, effective, and trusted marine tools.
