Here is Fish Razr on their Dredge Pulling Kit with 4lb Fish Weight:
Everything you need to pull a dredge from a cleat on a smaller boat. The kit is available either in a waterproof box or mesh carry bag. Inside the kit is a yo-yo with 50 ft of 900lb rated elastic shock cord. One end has a loop to go around a cleat, the other has a 1000lb cork screw dredge swivel. A 900lb connector cable with double 1000lb corkscrew swivels is supplied to attach the dredge to the provided 4lb fish weight. These kits are designed for lighter weight dredges – large dredges can pull a tremendous amount of drag. You will still need to be able to hand line in the dredge in a hurry when the fish of a lifetime peels off the dredge and piles on your lure.
