How the rig works
The lip forces the lure down to a depth set by lip size, line diameter and retrieve speed. Deflecting it off rock, wood or weed creates the erratic change of direction that triggers most strikes.
Smallmouth Bass behaviour
Crayfish, gobies and small baitfish. Feeds hard in current seams and around rock.
Cool, clear lakes and rocky rivers with current. Prefers gravel, boulder and rock flats over weed.
When to fish it
Clear water, 55–75°F (13–24°C), moving water or wind-blown rock banks.
Smallmouth Bass tips
- Match crayfish and goby colours — browns, greens and translucent patterns.
- Lighter line gets more bites in clear water; a fluorocarbon leader helps disguise braid.
- Fish current breaks: the slack pocket behind a boulder holds fish.
