Trail Chasers® Blue Survey Markers, 6" Ground Marking Flags (Whiskers) with Aluminum Stakes, 25 Pack for Survey & Construction

I use these to mark certain plants at a nature preserve. They stand out if you are looking for them, but they do not overwhelm the vista. They have been in the ground for over a year and have shown no aging. This is my 3rd set.

I use this to mark important points in our drip irrigation system. This color shows up but doesn’t leap out at you in our Sonoran Desert landscape.

I run a shooting competition called the Steel Challenge. I use these to mark where the targets go each month so I do not have to remeasure every month. They work great.

We use these for marking the corners of batters boxes. Work perfectly for this application.

I contacted Trail Chasers because I needed a custom package of multiple colors to mark firing lines and target positions on multiple bays at my outdoor shooting range. They got me what I needed and the markers are working great! They have survived the riding lawn mower and spring sun.

It's not very durable. Invest in a more expensive one that will last. We set some down in the beginning of the fall and the whiskers were totally gone by the end of the fall
