Extremely Accurate Sprinkler Calibration System Measuring Rain Gauge Pro-Pack Tool for Outdoor Green Lawns 8 Cups

worked pretty good

I love the flagged and numbered water cups. In addition, the extra spikes they give you make a handy way of marking your holes if you are doing measurements on multiple days. Keep ‘me flush to the ground and you won’t even know they are there. My biggest complaint is that it can be a bit hard to read the measurement. Would be nice if the lines were colored in black or something. I also gave a 4 on accuracy mainly because I’ve had a couple of suspect measurements. Could be just the way my sprinklers work or maybe the post interferes or something. Not sure. In any case, the important thing is consistency between runs and I’m almost done tuning my lawn watering for which this product overall was great.

A great way to test your sprinkler system. Have used it to measure output so I can set watering times correctly. Have now started using them to measure coverage within a specific zone to adjust heads and replace nozzles with diminished output due to mineral build up in the nozzles. Very glad I bought these.

Easy to use and I was able to identify watering zone needed changes based on their water output. My lawn now gets equal watering in all watering zones.

I finally made the time to use this and it is helping me greatly to assure my lawn is even even water distribution. Very accurate and handy.

Was able to correct several areas of my sprinkler system.

Works great!

Perfect
