We also use the RedBob bell targets and came up with a modification to make a hood that can house a small lighting unit that we have found very handy.
The first prototype was made for us locally and has proven to be a very good idea.
When he was shown what we had done Bob also liked this idea and has added the self illuminated type to his range.
You are welcome to come over to see us at RMTC and take a look at our set-up and the bell target mods etc.
We also have these bell targets set-up at 10 meters on our permanent range to make an interesting change from paper punching now and again.
