Handlining is an awesome way to keep the bait in the strike zone. If you only have 1 handline it is also compatible with other trolling methods like 3-way, snap weights, lead core… if you have another angler in the boat.
If you are fishing waters that allow multiple baits I would recommend starting out with 5′ and 10′ leaders. You can go longer but it is just easier to start with a shorter leader. Connect the 5′ leader on the 2nd or 3rd clevis up from the weight and the 10′ a couple up from that. If you are picking up debris, move them up. Dive depth rough estimate for a shallow diving lure is 1.5″ per foot of leader so on a 5′ leader the bait will run about 8″ below the point where it attaches to the clevis.
The 1.25 lb weight that comes with set is a good all around weight to start with. With this weight, the cable will be at about a 45 degree angle for trolling speeds between 1.5 and 2.5 MPH. That’s a good starting point.
Learning to handline is fairly easy. While trolling, let the leader(s) out and lower the weight till it contacts bottom. That’s it, your fishing. You can choose to drag the weight, keep it just off the bottom, or walk it along by pulling forward and letting it back. Walking usually produces better but not always. Don’t be afraid to experiment.
Things to remember:
Never wrap the cable around any body parts that you do not want removed.
Keep the cable away from the propeller. Pay attention to this when making turns.
If trolling using a bow mount, leave your main motor in gear so the prop does not turn.
