Use live bait/cut bait. I use a single hook, with a piece of bluegill on it...toss it right by them and they go to it each time...it may be harder during breeding but they will take it eventually. There is no set time to catch a gar, its all different times of the day, even at night. In the summer/fall I like to use a stickbait, bleeding shad, thing is you got to really give it to them to get a good hook set. Three places on a gar to get a hook set, tip of the nose, throat/corner of mouth of lower jaw...if you really really hit into one hard you can go thru his top jaw but even that is iffy at best. You can use a bobber or deadline or sight fish for them, I do all three depending on the gar, if one doesnt work I do the next and so on.
