HOW TO CLEAN YOUR CATCH WITH ROCK-IT:
1. Attach a 10-foot nylone rope (1200 lb. test strength minimum) securely to the snap swivel furnished with your Rock-It. You may want to vary the length of rope, depending on the design f your hull and the horsepower of your motor. Once you find the length that works best for you rig, just leave the rope permanently attached to the swivel and you're set!
2. Fill Rock-It no more than half ful of fish at a time - it's so quick and easy there's plenty of time to run a second batch!
3. Attach swivel to nose cone of Rock-It. Fasten other end of rope to port (left) side of boat transom, approximately a foot above water line. IMPORTANT NOTE: Ideal height will vary with hull pattern and motor horsepower - some adjustment may be necessary to get the optimum rocking action out of your Rock-It.
4. Make sure you lock the safte catch on the trap door!
5. start boat moving forward. Motors of 10HP or less should be moving at moderate speed.
6. Now it's time to put our Rock-it overboard on the port (left) side and play out the rope. Be careful not to get your fingers or any tackle caught in rope. Don't throw Rock-it overboard - gently place it in water with the nost cone facing in the same direction as the boat is moving.
7. If speed is too slow, Rock-It will sink. Increase speed until Rock-It rides on the surface of the water. Your Rock-It will work most effectively if it rides just in front of the port side wake of your boat on a sort of downhill plane of water. This helps it rotate. As you look backward, your Rock-It should be riding just to the right and in front (outside) of your wake.
8. Adjust your speed so that Rock-it  makes the maximum vigorous vertical agitation (rocking up and down - where do you think we got the name, anyway?). NOTE: Rotation does not need to be fast. Just steady. This is the part where you can adjust the length of rope you use to find the optimum length that works with your boat.
9. If you over-scale by pulling your Rock-it too long, it will not damage the skin or flesh of your catch, but it may cause damage to the head and fins. We suggest you try 100 yards at a time and check off and on until you find the optimum distance for your boat.
10. It will take LESS DISTANCE to clean soft-scaled fish like crappie, and more distance for hard-scaled fish like bream and bluegill. That's why it's a good idea to check after every 100 yards. You can also use your Rock-It to "de-slime" catfish - but a much shorter run is required for this than for normal scaling.
