Summary
What this review covers
This review looks at the blue flag color, 100-pack count, 15-inch wire staff format, and role in temporary lawn and sprinkler mapping.
Pros
The upside
- Blue flags create a clear visual cue around sprinkler heads, gauge cups, lawn edges, and station paths.
- The 100-pack gives a generous supply for repeated output checks through the watering season.
- Fifteen-inch wire staffs press into lawn soil, bed edges, and patch-repair areas.
Cons
The tradeoffs
- Flags should be gathered before mowing, edging, or aeration work.
- Short written notes still need a card, label, or notebook entry beside the marker routine.
Who it is for
Fit and feel
What to know:

Breakdown

Blue flags for sprinkler mapping
Swanson Tool Co FBL15100 Blue Marking Flags give sprinkler checks a visible marker that can stand near a head, gauge cup, dry edge, or station path. The pack includes 100 flags with 15 inch wire staffs.
The blue color is useful when the garden record needs a separate visual cue for one station, one side of the lawn, or one group of output readings.
Useful during timed watering checks
Sprinkler output checks work well when each checked spot stays easy to find. Place a flag beside a gauge cup, beside a head, or at the edge of the watered pattern, then write the station name and reading on a card or notebook page.
The flag holds the place while the note holds the detail.
A simple refill for repeated checks
A 100-pack suits a season of setup notes, new seed watering, body-height checks, rotor adjustments, and lawn-edge mapping. Keep extra flags in a dry caddy near catch cups, weatherproof cards, and marker pens.
Pull the flags after the route has been recorded so the lawn is clear for mowing and regular garden work.
Good use
Choose these flags for named sprinkler stations, catch-cup spots, lawn repair edges, hose-route notes, and temporary mapping around backyard watering work.
