I thought I was going to have to make a video for Youtube on how to use a disgorger, but I found this on another site.

Disgorgers are great for unhooking gills and other small-mouthed fish. They're all I use.
Lindy sells one:

Wacker Baits also sell them, and you might be able to find them at Cabela's, Bass Pro and FishUSA.
You can also make your own. A small stick with a notch on the end will work, too.
