What is a typical trolling speed?

Most freshwater trolling falls between 1.5 and 3.5 mph (1.3–3.0 knots). Saltwater trolling for pelagics like tuna or wahoo can reach 6–12 knots. The right speed depends on the lure type and target species.

Does trolling speed affect lure depth?

Yes. Increasing speed causes diving lures to run shallower, while decreasing speed lets them dive deeper. Many manufacturers publish speed-vs-depth charts for their diving plugs. As a rough guide, a diving crankbait at 2 mph runs deeper than at 3 mph.

What is the difference between knots and mph?

1 knot equals approximately 1.1508 mph or 1.852 km/h. Marine GPS units display speed in knots, while many freshwater anglers use mph. This calculator lets you work in either unit.

Why does walleye trolling require such slow speeds?

Walleye often feed in cold water where slower presentations trigger more strikes. The typical range is 1.5–2.5 mph. Stick baits and spinners worked slowly stay in the strike zone longer and mimic sluggish baitfish.

Can I troll too fast?

Yes. Exceeding a lure's design speed ruins its action — spoons spin erratically, crankbaits blow out and rise toward the surface, and soft baits tumble unnaturally. Check the lure manufacturer's recommended speed range for best results.

How do currents affect my trolling speed?

GPS shows speed over ground, but current affects how the lure behaves. Trolling into a current at 2 mph GPS may feel like 1 mph to the lure. Trolling with the current at 2 mph GPS may produce too little action. Adjust speed based on lure behavior, not GPS alone.
