Best Kayak GPS

Navigating your kayak on an unfamiliar body of water can be daunting, especially if you are a less experienced paddler. Once you have ventured far from shore, it can be difficult to make sense of your surrounding and exact location without landmarks to help you make sense of your bearings. The problem is made even more difficult should you run into adverse weather. However, investing in a reliable GPS device is an easy way to overcome these navigation difficulties. A quality GPS system will allow you to take to the water with confidence, allowing you to always determine your exact location and access a variety of useful data sets.

GPS Systems Explained

The global positioning system utilises radio frequencies from space-based satellites to allow users of GPS receivers to determine their exact location on land or water. This positioning system uses numerous satellites to provide accurate readings at all times, meaning you can always ensure the location data you are receiving is reliable. You may encounter GPS trackers that boast compatibility with WAAS. This refers to the Wide Area Augmentation System and is essentially an updated version of conventional GPS systems. Not only does this system provide better levels of accuracy, it also allows for better availability of positioning services.

However, GPS is not the only radio navigation system currently operated and many GPS devices today support communication with other services. One such system is GLONASS. This Russian service operates in a similar manner to the GPS service, but combines the readings of both to provide you with significantly higher levels of accuracy.

Waterproof Performance

If you are looking to purchase a GPS system for use when kayak fishing, you need to consider the importance of water resistance. Simply paddling your vessel can result in sizeable splashes that can come into contact with your GPS device. Therefore, you need to ensure that it is built to withstand exposure to water. A waterproof rating of IPX7 should be sufficient to ensure the electronic components of your device survive any contact with water. More advanced GPS models are designed to withstand full immersion for a limited time, while others feature housing that allows the device to float should you drop it overboard. This allows for instant retrieval of your device.

Mapping Capabilities

If you are unfamiliar with the specifics of how GPS devices work, you should consider mapping capabilities before you purchase a new system. Not all GPS units come with the same maps preloaded onto them. You want to ensure that any device you buy is loaded with useable maps that reflect the location you are looking to use them in. A basic worldwide map should be included as a standard feature, but you should also ensure that your device allows you to expand the map library with ease. Many GPS models will allow you to download maps readily, provided the unit is wi-fi enabled. A microSD card slot is also a must if you want to regularly update your device with new and improved maps. Even if your chosen device does not include a memory card slot, you should make sure it provides a basic level of connectivity. The most basic of models usually allow you to plan your routes and waypoints on a separate device, before transferring the data to your GPS unit via USB. Bluetooth connectivity makes transferring this type of data even more effortless.

Screen Size & Resolution

The larger the screen of your GPS unit, the more expensive the device will usually be. Therefore, you need to think seriously about about how you will be handling your GPS device. If you want a device that can be kept close by at all times and operated in a handheld manner, a smaller device and screen size should be sufficient for your needs. You can always move the screen closer to your eyes if you struggle to make sense of contour readings and other data. However, many people like to keep their GPS units fixed firmly in place by mounting them onto the hull of their vessels. In this case, you should probably look for a device with a significantly larger screen size measuring at least 7 inches. This should prove large enough that you can determine the details on screen, even when some distance from the GPS unit. If you are interested in purchasing a GPS system that provides you with high levels of topographic detail, investing in a screen with significantly high resolutions is also advisable.

Battery Life

The type of battery your GPS unit will require will usually be determined by the amount you are prepared to invest in the product. The most basic GPS models out there will use disposable AA batteries that will need replacing or replenishing with rechargeable batteries. With GPS enabled, these types of batteries will usually provide you with enough operational time for one or two  (tandem) kayak excursions. If you enjoy getting out onto the water regularly, these types of batteries will probably prove too limiting. Instead, look for units that incorporate lithium-ion batteries that can be quickly recharged via a mains power source.
