The innovative B&G H5000 instrument system is powered by a smart Central Processing Unit (CPU) with the ability to run three levels of software, Hercules, Hydra and Performance. Hercules is specifically designed for racing yachts, giving you additional features geared towards success on the race track, inshore and offshore. On top of the benefits of provided by Hydra, Hercules adds a whole tier of race functionality with the advantages of more accurate data and more race specific features, alongside web-browser integration for ease of set-up. By adding optional sensors, you can benefit from 3D Motion wind correction, offsetting the unavoidable discrepancy of induced wind errors caused by boat motion, for more accurate results. An integrated Polar table provides target boat speed, target wind angles and performance monitoring for a real racing advantage. Enjoy advanced calibration with heel/linearity correction of boat speed for supreme accuracy and increased sensitivity of boat speed data to real accelerations / decelerations with Dynamic Damping. Enhanced HV display control provides a 10Hz update and context switching, automatically changing the display setting between pre-start, upwind, reaching and downwind. Hercules also provides enhanced communication, Polar table configuration and Start Line information. It is effortless to set up and calibrate with the new H5000 web-browser interface, however complex the system. -Hydra spec plus: Hercules is packed with all the powerful features of the Hydra system, but adds unique functionality for serious racers. -HV Display Context Switching:Enhanced HV display control provides a 10Hz display update and context switching, automatically changing the display setting between pre-start, upwind, reaching and downwind.
