What is the primary purpose of the Split-Shot Rig?

The primary purpose of the Split-Shot Rig is to control the desired depth and feel of the bait. This rig incorporates small weights, known as split shots, that can be pinched onto the line at various intervals. By adjusting the placement and number of these weights, an angler can fine-tune how deep the bait is presented in the water column, allowing it to mimic natural movement and location of prey effectively. This adaptability is essential for catching various species in differing water conditions and achieving the best results based on where fish are located.

The other options do not accurately define the specific functionality of the Split-Shot Rig. It is not limited to deep waters; rather, it can be used at various depths depending on the angler's needs. Additionally, it is beneficial for a range of species, not just warm-water ones. Finally, the rig is versatile and can be used with various types of hooks, not strictly fixed hooks, which limits the utility of the rig.
