# Launch monitors > Canonical: https://pinflag.io/answers/launch-monitors Range numbers, finally on the course where the decisions happen. **Which launch monitors work with PinFlag?** Trackman, Garmin and Rapsodo files import directly. Every other monitor, SkyTrak and Foresight included, imports through a mapped CSV: you tell PinFlag which column is the club and which is the carry, set the units, and the session comes in, up to 5,000 shots at a time.

Those patterns then stand behind every predictive strokes gained number on the course and every dot in Shot Cloud. Outliers are flagged for you to judge rather than silently deleted, so the pattern is yours in every sense.

A launch monitor makes the pattern yours and moves the label to Measured, and on-course shots you log build your pattern too.

Per-club carries from your imported sessions make a twenty-yard hole between two clubs visible at once, which is invisible on a range where every ball is a fresh attempt at the same target. The free launch monitor analyzer on pinflag.io reads a session export in the browser and flags gaps with what each pattern costs in strokes.

A Trackman session export imports as it is, becomes a per-club Measured pattern, and from then on prices every target you aim at on the course with your real carries and spread.
