Mounting & clearance: You’ll need to ensure proper mounting so that it doesn’t interfere with scope or your field of view.
Calibration & alignment: For angle / cant features to be accurate, you’ll need good calibration in all expected mounting orientations.
Learning curve: With multiple features bundled in one device, expect a bit of user training to get the most out of it.
Power & durability: Battery life is strong (designed for ~600 two-minute stages) and the body is water resistant, but for long field use check charging logistics.
Integration with other tools: It can sync with other SG tools like timers and the “Drills app” for full match and training data logging.
Compared to the earlier SG Pulse (non-Pro), the Pro has:
An LCD + LED display (instead of just LED)
A numerical digital level / cosine (angle) indicator (not just color or LED cues)
On-device handling of DOPE card, muzzle tracking, zeroing (not only via app)
Support for stage timer (which the base model may lack)
So the Pro is more self-contained, with more on-device functionality to reduce reliance on a smartphone during a match.
