It is crucial to have a bright, clear screen on your fish finder, which helps you easily take a look and read all the things inside. Cleaning the screen is an important factor since advanced fish finders use sonar technology. Thank this, you will get all important information including depth, temperature, bottom composition and the presence of fish.
Most of the causes that make your screen unclear are water smears and spots. This may come from rain, waves, splashes, and even playing fish. Leave water drying on your screen can produce ugly water spots. After a period, they will reduce your screen clarity, and the minerals in the water set into the lens make it become difficult to remove.
Things Need To Avoid
Abrasives: The first rule you have to remember is that do not use an abrasive glass cleaner when cleaning the glass with anti-reflective coatings. The abrasives possibly eliminate all the coating. In addition, if the coating is removed, you will begin to scratch the glass itself. So never clean screen with this in a dry or liquid form. Besides this, do not use paper towels contain fibers to dry the screen because they can make the surface scratch.
Ammonia or Alcohol Based Cleaners: These kinds of cleaners literally remove anti-reflective coatings as a solvent. Although they could clean the water spots from the screen, over time, after the coating is removed, other ambient light will be harmful to your eyes when you look at the screen. Moreover, the screen easily clouds up, and eventually cannot use.
Rain-X: You may think about using Rain-X to clean your fish finder screen, but do not use this. It is made with polymer substances which will exactly adhere to, and remove the anti-reflective coating, and then the screen will no longer be anti-reflective. If you use this, you will not be able to look at the screen during the day.
