The best equipment to develop extra strength in one's arms among the options provided is Paddle and Mitts.

Here's why:

1. Pull Buoys: These are used in swimming for leg training. They are placed between the thighs to immobilize the legs and help increase upper body strength. However, they are not primarily used for arm strength development.

2. Paddle and Mitts: These are used in swimming to increase water resistance, which makes the arms work harder to move in the water. This increased resistance helps to build arm strength, making Paddle and Mitts the best choice for developing arm strength among the options provided.

3. Weighted Dive Rings: These are used for diving training and underwater games, not specifically for arm strength development.

4. Floats and Kickboards: These are used in swimming primarily to support the swimmer's weight in the water, allowing them to focus on their kick technique. They are not used for arm strength development.
