Detailed description
Detailed description
Designed for Garmin chartplotters, Navionics+ inland waterway charts for the UK and Ireland provide a comprehensive mapping solution for coastal and river navigation. They cover major lakes and rivers in detail, such as the Thames, Medway, Mersey, Avon and Tweed in the UK, as well as the Shannon in Ireland, including lakes such as Loch Ness and Lough Neagh.
Detailed navigation data
These charts integrate bathymetric contours with a precision of up to 0.5 metres (1 foot), enabling clear visualization of the seabed structure. This precision is useful for fishing and navigation in complex areas such as marshes, canals, harbors and marinas. Users can customize the display with up to 10 depth shading ranges by colour, facilitating quick identification of target depths. A shallow water shading function also allows setting a specific depth for a visual alert of areas to avoid.
Advanced features and updates
Auto Guidance+™ technology is integrated to calculate a suggested route from dock to dock. It takes into account boat parameters, chart data and frequently used routes, simplifying navigation in channels, tidal rivers and marina entrances. The charts include a one-year subscription to daily updates, accessible via the ActiveCaptain® app, ensuring access to the most recent information. The user interface is designed with vibrant colours and a Navionics®-style colour palette for easy reading and customization of views with various map layers.
Integrated mapping solution
This solution combines Garmin and Navionics content, offering unified mapping. Charts are typically supplied on an SD/Micro-SD card. For extended capabilities, an upgrade to Garmin Navionics Vision+™ mapping solutions is available, offering additional features such as high-resolution terrain shading, high-resolution satellite imagery, aerial photos, 3D views (Fisheye and MarinerEye), and dynamic lake level management.
