Tone tubes, object targets construction

[Hwy1DG]

We have a great piece of land that has been approved by the city to eventually install a basket course. But until that happens I want to install a temp object course to get the community excited about the notion of a new course.

Can any one point me in the right direction on how to construct a "tone tube" or have any ideas on what some cheap and legit objects or targets are?

How about this?

I see you are from the Santa Cruz area, do you have any more information on the location/progress?

there have been stakes hammered into the ground with 5 gallon buckets glued on top at two courses that were in progress here locally

I have a few tone poles if you want them. I sent you a pm with my contact info.
