I've always appreciated the time and effort that Crosman put into their targets. I have an early Targlite which is huge and works better than anything else, love the light bulb which allows to see where the shot hit.
This is the later, smaller Targlite which includes the return line. This is the only example that I can recall having ever seen unused in the box, complete with everything. As a matter of course, these get destroyed in use. Pretty unique example. Priced pretty reasonable, imo.
