In the chartplotter screen protectors product group, you will find model-specific protective films for the most common plotters: Raymarine Element 9 screen protector, Raymarine i40 meter screen protector, Simrad NSS12 EVO3 screen protector, and Lowrance screen protectors for both 7" (Elite/Hook) and 9" (HOOK²/Reveal and Elite/Hook) screen sizes. The protective film is a thin, transparent film that is installed directly over the plotter screen to protect against scratches and UV radiation without interfering with the readability of the screen.
A plotter used at sea is constantly exposed to sunlight, salt water and abrasion from, for example, the sleeve of a raincoat or the corner of a map, which over time dulls or scratches the surface of the screen – this is especially problematic for touch-screen models, where the brightness and sensitivity of the screen are essential for use. A screen protector is an inexpensive way to extend the life of the plotter and maintain its resale value, as a scratched screen is often more expensive to repair than the price of the entire protective film. Always check the exact model marking of your plotter before ordering, as screen protectors are cut for each model and are not compatible between different models or even different generations of the same manufacturer. Installation can be done yourself in a few minutes on a clean, dry screen.
It is a good idea to replace your screen protector as soon as you notice scratches or it starts to peel off at the edges, as a peeling protector will collect dirt underneath and can ultimately impair the readability of the screen more than it protects it. When installing, it is a good idea to work in a dust-free area and use the included squeegee card to ensure that no air bubbles remain under the film – this is especially important for touchscreen models, where bubbles can interfere with touch recognition.
Some screen protectors also include an anti-reflective coating that improves screen readability in bright sunlight – a particularly useful feature on the high seas, where light is strongly reflected from both the sky and the water surface. The protector can usually be removed and replaced without leaving any residue on the adhesive surface, so it can be replaced multiple times over the life of the plotter if necessary.
A screen protector is cheap insurance for protecting an expensive electronic device – a purchase for a few tens of euros can save you hundreds of euros in repair or replacement costs.
Screen protectors are available in both matte and glossy versions – matte reduces glare but can slightly dull color accuracy, while glossy preserves original color reproduction better but is more reflective in direct sunlight. The choice depends on whether you use your plotter more in bright daylight or in a more sheltered cockpit where reflections are not as much of an issue as on an open deck.
