TheStack Radar Golf Launch Monitor - Portable Speed & Wedge Trainer

In this review of the TheStack Radar, the bottom line is simple: this compact golf launch monitor is ideal for players who want reliable speed metrics and a practical wedge-training workflow. It measures swing speed and ball speed, estimates carry distance and smash factor, and pairs seamlessly with TheStack App so data flows straight to your phone. For coaches and committed practice-focused players who use speed training and gamified wedge sessions, the Radar delivers clear, actionable numbers without the complexity of a full launch monitor suite.

Key Features

• Accurate speed readings: Measures both swing speed and ball speed so players can track changes in tempo and power during practice.
• Estimated carry and smash factor: Calculates an approximate carry distance and smash factor to help evaluate contact quality and distance control.
• Bluetooth app pairing: Connects directly to TheStack App on iOS and Android for automatic data transfer and session tracking.
• Stack Wedging integration: Includes a full-featured wedging app with gamified drills and a 1-month free trial on iOS for focused wedge practice.
• Bundled putting guidance: Offers access to Stack Putting on iOS to add guided putting practice and tendencies analysis to your routine.

Who It's For

TheStack Radar is best for golfers who prioritize speed training, range wedge work, and simple on-course checks of swing and ball speeds. Players who already use TheStack training system or want a lightweight device to track measurable progress will appreciate the automatic Bluetooth syncing and the gamified wedging mode.

This is less appropriate for golfers who need a full-featured launch monitor with advanced shot-shape, apex height, or spin data; those users should look at higher-end systems. Also, anyone who wants wedging features on Android should note that Stack Wedging is iOS only at this time.
