Boasting the same lake database and features as LakeVü HD, LakeVü HD Ultra enhances the fishing experience by providing more robust features designed specifically for a chartplotter or multi-function device. Granting more detailed access for everything above and below the waterline, LakeVü HD Ultra is Garmin’s best inland water cartography to date and can be purchased and used as an accessory with the new GPSMAP 547 and 741, new echoMAP series and newly-announced GPSMAP 8000 Glass Helm series. Gaining a whole new perspective on freshwater navigation, LakeVü HD Ultra features patented Garmin Auto Guidance technology. By adding a LakeVü HD Ultra card to a compatible Garmin chartplotter, the user can enter the desired location and Auto Guidance instantly searches through relevant maps to create a safe path designed for the dimensions of the boat. Auto Guidance will then provide a visual path that allows the user to travel to the destination while avoiding shallow water and other charted obstructions. When Auto Guidance is coupled with a Garmin autopilot system, the autopilot can engage to follow the determined route and will automatically keep the vessel on course. Water level can also be adjusted with the new Dynamic Lake Level feature. With Dynamic Lake Level, the mariner can adjust the water level of the lake depending on the surplus or lack of rain that the area received. By adjusting, the data is modified on the chartplotter to match the current conditions. Contours and spot sounding values will adjust and the shoreline will depict the current topography of the lake.
