Chapter 5: Navigation Equipment
Read the manuals for all navigation and communication equipment before using these systems.
Depth Finder (If Equipped)
Do NOT use the depth finder as a navigational aid to prevent collision,
grounding, boat damage or personal injury.
When your boat is moving, submerged objects will NOT be seen until they
are already under your boat.
Bottom depths may change too quickly to allow time for your boat to react.
If you suspect shallow water or submerged objects, run your boat at very
slow speeds.
