With the Scrubbis Indicator Plate you can see when it's time to scrub away fouling on your boat hull. By having an indicator plate under the water where you have your boat you will get the same fouling on the plate as on your boat hull. Tie the indicator plate on your boat or on the jetty where you store the boat. By regularly check the indicator plate, you can see how much fouling there is on your boat hull. You can then easily determine when it is time to clean the hull with Scrubbis.
