This what they look like. 
 
Flip the two tangs out and use a very long rubber band and attach it directly to the barrel. No cost at all and in my case works very well. Make sure the alignment is good the face of the chrono is perpendicular to the pellet trajectory and play around a bit how far back the chrono needs to sit under the barrel to get good repeatable shots. Use the feedback number you get each shot to fine tune.
