Why We Recommended It
Great Depths turns your iPhone or iPad into a powerful digital depth finder, and it’s currently free for a limited time (originally $0.99). Unlike other boating apps that charge hefty subscriptions, Great Depths covers the entire US coastline, the Great Lakes, Lake Champlain, and many more inland waterways with NOAA RNC nautical charts — all without ads. The app automatically adjusts depth readouts based on real-time tide and lake levels, so you always know exactly how much water is under your hull. Whether you’re cruising from port to port or exploring a new anchorage, the built-in mileage calculator lets you measure distances between any two points instantly. All chart packages sync across your iOS devices and are stored locally, meaning you never have to rely on spotty cell service. If you need a dependable, lightweight tool for safe navigation, this is the perfect time to grab Great Depths for free. Don’t miss out on the chance to add this essential marine companion to your iPhone or iPad.
