you can take nylon rope and fray it out to catch them i have done it but a little bg works much better. gar have pretty poor eye sight so if you can see them throw a little bg right in front of them or any little baitfish they will eat it.i also catch alot of gars at night with cut bait i supend it on a cork to try and keep catfish away from it but gar have excellent noses they will track it down.
