Compare documented controls and setup details. Then record what actually reaches your own patch.
Six exact manufacturer records. One browser-local catch-can worksheet. Clear conditions, with no invented field tests.
Separate width and range controls are worth investigating for a rectangular patch. The published area is a maximum claim, not a result measured in your yard.
Pressure conditions not confirmed. Not our test.
Height adjustment is a setup choice, not a measured coverage advantage. Use the current model instructions and provide stable footing for the tripod.
Pressure conditions not confirmed. Not our test.
The two sides of width adjustment can be considered separately when planning a strip. Start with a short observed run rather than relying on the coverage number.
Pressure conditions not confirmed. Not our test.
A circular or part-circle pattern raises different boundary questions than a rectangular pattern. Its larger area claim does not establish better application or water savings.
Pressure conditions not confirmed. Not our test.
Maximum coverage, adjustment controls and your actual setup tell different stories. Keep them separate and it becomes easier to make a considered choice.
Read a coverage claim carefully ↗Record depths from one shared run. See the average and range, then scale that observed rate to a target you choose.
Open the worksheet ↗No account. No automatic watering schedule. Your readings stay in the browser.
Same rate assumed. An average does not describe every spot.
A boundary sketch helps you ask better questions than a coverage number can answer.
The useful distinction is what you can adjust and where the spray needs to stop.
A maximum area is a source claim with conditions. Keep it separate from a yard measurement.
Unknown pressure belongs in the record as unknown. It should never become a guessed specification.
