Read the yard.
Keep good notes.
Small-yard planning, source checks and measurements you can understand. No invented tests or water-saving percentages.
Choose by yard shape, not the biggest area claim
A boundary sketch helps you ask better questions than a coverage number can answer.
Oscillating and circular patterns: compare the controls
The useful distinction is what you can adjust and where the spray needs to stop.
What an “up to” coverage number leaves out
A maximum area is a source claim with conditions. Keep it separate from a yard measurement.
Keep pressure and setup in your measurement notes
Unknown pressure belongs in the record as unknown. It should never become a guessed specification.
Make a useful catch-can record
Measure water depth at several positions during the same run, then keep the conditions with the numbers.
Plan a short check for a narrow rectangular patch
Define the edges first, adjust deliberately and observe before recording a full test.
An estimated runtime is not a watering schedule
The target depth is your input. Local conditions decide whether that target is appropriate.
Keep a seasonal care record for a portable sprinkler
Good maintenance notes start with the exact manual, the parts you inspect and the changes you observe.
