bobber stop for gar?

what are yall using as bobber stops for gar fishing? i have been trying a few different things but would like some ideas..needs to be something that can go through the eyes on my rod freely and reel onto the spool as well while maintaining the ability to be moved, so i can change the depth..pics would be awesome..thanks

got the bobber stop figured out, i just needed to add a small plastic bead on top of the bobber..i can take a picture if anyone else is curious what i came up with, not too sure why it took so long to get it right..

Now that you've got it figured out, I use a uni knot on the main line with a bead below it... Lol
