When fishing with spinnerbaits, it's important to vary your retrieval speed and depth to entice fish. You can retrieve the spinnerbait at a steady pace or experiment with pauses and jerks to imitate injured baitfish. Casting near cover, such as weeds or submerged structures, can also lure fish by mimicking prey hiding spots. Another effective technique is "slow-rolling" your spinnerbait, where you retrieve it just above the bottom at a slow speed. This can be particularly effective in triggering strikes from bottom-dwelling fish. Remember to keep an eye on your line for any sudden movements or twitches, as this could indicate a fish has taken interest in your spinnerbait.
