Big Crazy Golf Swing Speed Trainer Adjustable - Tempo and Power

In this review the Big Crazy Golf Swing Speed Trainer Adjustable is evaluated as a practical, club-connected training aid for golfers seeking more swing speed without changing their setup. The bottom line: this trainer is best for players who want to practice tempo and add clubhead speed using their existing drivers, because it attaches to compatible Callaway-style adapters and offers three removable weights to progress training over time. It is a straightforward tool that prioritizes muscle memory and warm-up work rather than replacing full swing instruction.

Key Features

• Adjustable weight system: Three included weights (155g, 190g, 235g) let golfers increase load gradually to build strength and speed during repeated practice swings.
• Club compatibility: Designed to work with a wide range of Callaway-style drivers from the 815 generation forward, allowing training with a familiar club setup.
• Quick removable design: The training head is removable and replaceable with simple operations so it can be swapped on and off before practice or warm-up.
• Non-slip rubber sleeve: A rubber sleeve increases friction against the trainer surface and protects finishes while making the unit easier to screw on and off.
• Warm-up and practice focus: Recommended short sessions of 10-15 minutes, three times a week, to help improve swing speed and muscle memory without lengthy workouts.

Who It's For

The trainer suits mid-handicap to low-handicap golfers who want a compact, progressive training aid to add swing speed and tempo practice to their routine, and who already own compatible driver models or shafts. It is particularly useful for players who prefer training with their familiar club head and shaft rather than a generic weighted bat.

Players who should look elsewhere include those with incompatible driver models such as RAZR or RAZR TOUR drivers, or golfers who need a full coaching program rather than a weighted swing attachment. Also, anyone uncomfortable with attaching hardware to a valuable shaft should weigh the risk, as a small number of customers reported issues when used improperly.
