Decide where the boat belongs first
Holding the wrong spot very accurately is still holding the wrong spot. Pick the casting angle first and let Spot-Lock help you keep it. Spot-Lock holds a selected boat position using GPS and motor corrections. It does not choose the best casting angle. Before engaging it, identify the target, your casting distance and where the lure needs to travel. For an offshore pile, that usually means holding away from the pile with room for the bait to reach depth. For a current seam, it means positioning so the retrieve crosses the useful water instead of immediately sweeping out of it.
Let the boat settle before judging the cast
Approach slowly and engage the function with clear water around you. Momentum, wind and current can still move the hull while the motor corrects. Wait for that initial movement to settle, then cast. If the boat keeps swinging enough to pull the lure off its path, move to a position with better alignment or fish manually. Repeating a bad cast from an automatically held position does not improve it.
Hold upstream with a reason
In manageable current, a position above or beside a target can let a jig or plastic drift toward it. Leave room for the lure to sink before reaching the fish. Watch the line: if it bows far downstream, you may need a shorter cast, more weight or a different boat angle. Never use a productive seam as a reason to crowd a dam restriction, navigation lane or other hazard.
Separate boat position from beam direction
A motor-mounted live-sonar transducer can turn as the motor corrects. The boat can remain near its saved position while the target leaves the screen. Watch the motor's direction and reacquire the beam deliberately. A compatible independent aiming system solves a different problem from position holding; one keeps the boat near a point and the other manages where sonar looks.
Move when the angle stops working
Disengage before relocating, then approach the new position slowly. Use any position-adjustment feature only if it is supported by your navigation system and you understand its controls. Leave clearance for the full boat, not just the motor shaft. If holding becomes erratic, take manual control and move into open water before investigating calibration, power or GPS issues.
Put it into practice
- Choose casting distance before engaging Spot-Lock.
- Allow room for the hull to swing and the motor to correct.
- Reposition when drift pulls the lure away from the target.
