How to Choose the Best Marine GPS

Maps and Charts

Like most products, Marine GPS devices are produced in a variety of forms, thus making it difficult to choose the right GPS for those who do not use it yet. Before choosing a GPS device, there are certain things one should take cognizance of. The initial step is to check the number of satellites the producer of the gadget has specified for usage. Some satellites make use of 12 which most times prove to be inaccurate when compared to GPS making use of 24 satellites.

Then you have to determine whether you want a portable device or a device that mounts on the dashboard of the boat. In a situation where you have a small boat, it is ideal for you to purchase a portable device. However, some people find it hard to understand what is being displayed on the screen because of the small size.

However, if you prefer to see information on a big screen, the mounted GPS is the ideal product for you. A lot of this mounted GPS work well with fish finders. In case you have a sailboat, it is recommended that you purchase the two forms of GPS. Hose with sailboats and larger yachts carrying a dinghy will often need both types. The portable model is essential in an unforeseen situation that requires the largest vessel to be unmounts.

Since you take it to sea, the least you can do is make sure your device is watertight to avoid any mishaps. Remember to check the specifications and comments if the unit is well presented as waterproof, not just as “water-resistant.”

As you were told, the GPS system is made up of 24 satellites. While this network provides excellent data accuracy and quality, it does mean that your devices need the power to capture and maintain the GPS link. In this regard, the latest generations show better performance, especially because they are equipped with a GLONASS system, very effective in capturing GPS links. In the same way, such a system saves you precious time to establish the initial connection with four satellites necessary to define your position.

Classic GPS displays your location and identifies potentially risky areas.

The GPS plotter gives you greater freedom by allowing you to trace your route, get the exact position of your ship on the screen, and even choose between several proposed routes to reach the same point.

The GPS sonar includes a good part of the instruments that you already find on the dashboard, which means a significant saving of space. This is the most sophisticated model, the price of which varies greatly depending on the brand and the size of the screen.

The principle of a mobile device is that it can be moved, so it must be easily manipulated and transportable to make a practical object. Think first about checking the weight and size of the devices: a model too heavy will weigh after several minutes of use and mobilize your two hands, while a model too large will not necessarily pass in your pocket. Also, check out the comments for ease of start-up, as some models sometimes include a specific program to facilitate the start settings.

The guarantee is already a good demonstration of confidence and durability. However, it is not necessary to rely on it systematically: it is not because a product is under the guarantee that it is necessarily of confidence since all the models of this category are required by law to be under guarantee. The difference may appear, however, over the duration of the warranty: the more it is extended, the more you can ensure that the product is durable and quality.

Another factor you should take to mind when you want to purchase the ideal marine GPS for your boat is the water-resistant of the device. You should consider where you want to make use of the device, is it near water or far away from water? Whatever the case, ensure to get the best marine GPS with water water-resistant.

There a lot of ways to know whether the device is waterproof. The rating goes from IPX0 to IPX8. Devices that have IPX0 written on them means they are not waterproof and this is virtually the case for IPX1, 2 and 3 also.

On seeing, IPX4 on a device, that means it is protected from water splashes, while IPX5 and IPX6 is a little bit more advanced. Seeing IPX7 rating on a device shows full waterproof of the device even though it comes with limitations. The IPX8 rating indicates full protection of your device from water damage.

Another factor to be considered is whether there is a usual manual that makes usage easy. Most of these manufacturers are indeed able to bring real qualitative know-how, where the mass distribution will generally be satisfied with just functional objects. Another way to do this is to use the Internet! By consulting several references, comparators, datasheets, customer, and user opinions, you will have enough information to ensure you choose an objectively sustainable model.
