Answer 4 quick questions to see whether Blue Tees Series 4 Ultra or Blue Tees Captain Air better matches how you play, what features you value, and how you want to own your rangefinder.
This is the central difference between these two Blue Tees approaches.
Both are 6x-class devices but the display and targeting philosophies differ.
Pick features that change decisions on your actual rounds.
The Series 4 Ultra still has an active official product page, while Captain Air is the newer connected direction.
Series 4 Ultra fits golfers who want a premium standalone 6x OLED laser centered on Auto-Depth Filter, Active Track, adjustable visibility and slope control rather than connected GPS being the main feature.
Captain Air fits golfers who want a 6x connected GPS rangefinder with front/center/back distances, Find My, club suggestions, True Distance and direct integration with the Blue Tees GAME ecosystem.
