The SkyCaddie SkyPro swing analysis and training tool looks to take on the likes of Swingbyte, 3BaysGSA, and others. The SkyPro connects via Bluetooth to your iPhone (the SkyPro iPhone app is free) to provide 3D graphics of your swing, along with data on your clubhead speed, swing path, club rotation, face angle, swing plane, impact position, tempo and more. Features that sound intriguing include the ability to compare two swings, built-in alerts to help identify swing faults, and drills. We so hope that SkyCaddie has done a good job with the user interface (better than with their ClubSG portal). Just remember: as with any of these mobile swing tools, if you are expecting a TrackMan, please keep your expectations in check. Stay tuned for our detailed review.
