TruSwing, Arccos, or Zepp? A swing analyzer you quit is a paperweight.

A swing analyzer you quit is a paperweight. TruSwing versus Arccos versus Zepp — I compared them as something that stays on the club.

Swing analyzers sit between launch monitors and teaching pro observation — useful tools with specific limitations. Three consistent options: Garmin TruSwing, Arccos Caddie, and Zepp Golf 2.

Garmin TruSwing: Clips to any club shaft, connects via Bluetooth to Garmin device or smartphone. Captures swing plane, club path, tempo, backswing length, face angle, hand speed. True swing mechanics tool. Price: ~$250.

Arccos Caddie: Shot-tracking system with sensors in all 14 club grips. Automatically records every shot using GPS — no manual input. Delivers strokes-gained analysis, driving accuracy, approach proximity, putts per GIR. AI Caddie provides pre-shot club recommendations. Performance analytics tool, not swing mechanics. Price: ~$230 + ~$99/year.

Zepp Golf 2: Glove-mounted swing mechanics sensor. Captures club speed, swing plane, tempo, backswing length, hip rotation. Connects directly to any smartphone. Includes video comparison features and drill library. Price: ~$100.

Data accuracy: TruSwing wins on swing mechanics (shaft-mounted, actually measuring the club). Arccos wins on shot-tracking accuracy. Zepp’s glove mounting produces less precise plane readings.

The practical distinction: TruSwing and Zepp tell you how your swing is moving. Arccos tells you where your game is bleeding shots. Ideally: Arccos identifies the problem, a teacher diagnoses the cause, TruSwing or Zepp helps practice the fix.
