This new model comes with the ability to display the information needed by surfers (time and level of tide), and use a smartphone app to easily select one of approximately 3,300 surf locations worldwide.
The wide front and high-definition MIP (Memory in Pixel) LCD enhance the readability of the display on standard functions such as Tide Chart, Moon Data, tide times, and sunrise and sunset times. It provides important information about current conditions at a glance, which combined with a suite of training measurement functions (distance, speed, tempo, laps, pitch) provide a lot of support for new challenged surfers around the world.
In addition to powerful functions, these new models also incorporate advanced design, structure and materials. The bezels of these models are made of resin and metal to better withstand the impact of underwater rocks. The bezel surface has a thin-coated stainless steel finish and a honed finish that creates an elegant look.
