what does it mean when someone uses the phrase "clipped down bait"??
I'll tell you what I think it is, then if I'm wrong we will both have learned something.
If you follow the line down from the rod tip there is a spot on a clipped down rig where the hook length (snood) leaves the main line by using a blood knot? or a three way swivel. the main line continues down to the lead weight but just above this is a bit of plastic or metal shaped like a hook and the hook (fishing) is hooked onto this so the hook line is tight and the main line is slightly loose.
I think the idea is so the bait (on the hook) stays close in behind the lead and provides less wind resistance during casting. Upon impact with the water surface the lead stops momentarily but the hook length carries on thereby unhooking itself from the bit of plastic.
If the snood leaves the main line (by knot or swivel) just in front of the weight and is attached to a hook back up the line, this is called "Clipped up". I have no doupt someone far more experienced than I will clarify if I've got it wrong! Cheers, Tony O-P.
