The SURF RAKE's tine raking technology is effective at removing materials from the sand in an eco-friendly way. By dropping the moving conveyor belt's tines into the sad from the top, the machine can be adjusted to clean depending on the environment's conditions. For seaweed, the SURF RAKE can scoop the big chunks off the top to reveal pieces that mingle with the sand bellow, instead of trying to scoop it all onto a screen and clogging the machine. The machine can be adjusted to dig anywhere from skimming up to 6" into the sand--allowing for either a deep clean or a more sensitive approach to not disturb the eco-system that rests beneath the surface of the sand. To understand more about how the SURF RAKE works, you can reference the illustrated video below or watch the operation video to get an idea of how it works.
