Deep Blue Marine Quick Clip w/Suction Cup Mount [QC-1]Quick Clip with Suction Cup Mount Whether trolling artificial or live bait, flat line clips are an important accessory to have on your boat. By reducing the angle at which your line enters the water, you can troll closer to the boat or keep your lure underwater more easily. Simply go from your rod tip to the release clip on your transom or engine cover, and then your lure or bait. Fewer tangles when turning and better presentation mean more fish.
