anyone here use jigging spoons in cold water ? if so please educate me
on how to use them.

I have several articles on this on my site. Basically, find fish on a
depthfinder, get directly over them, drop a spoon to the bottom on a tight line
and jig it up and down. Or drop it to their level if they are suspended. I
think it works better in clear water. Keep a tight line as the spoon falls,
that is when the bass will hit. Be ready to set the hook.

Try different ways of jigging, move it a few inches up and down, a couple of
feet each jig, pop it up fast then try a slow raise and drop. Vary until the
fish tell you what they want. And try different size spoons, usually it helps
to "match the hatch" and use a spoon about the length of the baitfish the bass
are feeding on.
