They look like this.

Mine is a lighter grey, the early ones were black and red.





Before I would go to BNC I would go to 1/4 phone plug. It's far easier for mounting nice flexable wire of any size to and easier to service. Also if you're fitting your ground lead on the plug I think you'll find the BNC a tight squeeze.

This is the way my Heathkit has been set up since I got it 15 years ago.
1/4" phono plug and a banana plug for the ground.

I like the seperate ground cause I can change from a probe to a alligator clip any time I want to without any changes to the uniprobe.

I bought my Uniprobe to use with my Knight-Kit VTVM. I seemed like it would more convenient than the two simple probes that came with the kit. I used the separate ground lead that came with the meter.
