A tide display device comprises a storage mechanism that stores tide information by surf spot. The transmission line allows near-field communications with another transmitter or receiver or transceiver system. The regulatable drive includes at least one first and at least one second flow path, which connect a fluid storage space to the coupling region, and it has a device which can be varied in its position by means of at least one actuator and which varies at least one passage orifice of at least one of the flow paths. By combining both types of reticles in a single reticle assembly, the shortcomings of each are minimized compared to a single reticle type by which the entire pattern is defined. The light diffusing applicator comprises at least one optical waveguide, a first termination coupled to a first end of the at least one optical waveguide, the first termination to couple to a light source and a light diffusing tip coupled to a second end of the at least one optical waveguide. The data is accessed using a security restriction defined by the custom data type.
