Caddie’s Call
For you if
- 4K UHD at ultra-short 0.496:1 throw ratio (100 inches from 3.6 feet)
- IP6X dustproof sealed engine handles garage environments
- Screen Fill auto-detects screen aspect ratio and fills edge-to-edge
- Lens shift for precise image positioning without digital keystoning
- 20,000-hour laser with no lamp replacements
- 3-year manufacturer warranty
Not for you if
- $2,499 is significantly more than 1080p alternatives at this throw ratio
- 16.7ms input lag at 4K 60Hz (higher than gaming-focused alternatives at 1080p)
- Fixed throw ratio (no zoom), requires precise ceiling mount placement
- No Golf Mode color calibration (unlike the AK700ST or LK936ST)
