Take all the paper out of the equation. Maps of all the arms of the lakes with markers for each beach. Watch your blue locator dot move as you do in your boat. Never be confused about where you are again or how far from fuel. Look for hieroglyphs, rope swings, and hikes to waterfalls on the map and get there without being confused. The app has social media, and help documentation right in the menu. You can star your favorite spots to remember them later! All listings of marinas have contact information so you can give them a call.
