Here is an easy way to see if your dog will like lure coursing.
Battery powers drill
bolt, washer, nut
spool of braided fishing line. I think my fishing line was 80 lb test.
Place bolt through hole in fishing line spool secure with nut.
Attach to battery powered drill.
Attach fishing line swivel. This provides an easy way to hook up the plastic bag lure and keeps the line from getting tangled.
Attach plastic bag.
Hold line with leather glove to keep tension on line when winding. This step works well for keeping the line going on the spool properly.
