Unlike static maps where you get what you get, Angling Technologies service is dynamic. Anglers can choose what they want to see and create any combination of map data that might help them understand the water better. Currently they have contours for over 6500 bodies of water nationwide and that number is constantly growing.
You can view contours on a large number of maps over the top of Bing, Google, or USDA imagery. The choice of imagery is important as imagery is captured at different points in time. Developing the most current is critical.
Angling Technologies provides a great value too. It’s only $15 a year and anglers get access to any new features or map information added during the year.
