Many ways to retrieve a spinner bait.
1 – You can cast it out and just reel it back in.
2 – Kind of hard to burn a 3/8 oz or wake one I use a 1/2 oz for either of those tequnics.
3 – You can cast it out and reel a few feet and then stop it and let it flutter a few feet, reel in again and do the same thing.
4 – You can also do what is called slow rolling, which is make a long cast let it sink to the depth you want and then reel it in just slow enough that you feel the blades turning.
5 – Cast it out and let it sink to the bottom, give it a good rip to get the blades turning then keep it in contact with the bottom.
6 – You can also use the tip of your rod to give the blades a little extra action by twitching your rod tip every so often, this will make the blades flash for a instant, or you can do it for the whole retrieve.
Good luck and have fun.
