A Fishing Glossary

Plain-English definitions for the gear and technique terms you'll meet across our guides. No jargon left unexplained.

Abrasion resistance
A line's ability to withstand scraping against rocks, wood, and fish teeth without weakening or breaking.
Backing
Thin line spooled onto a reel beneath the main line to fill the arbor and provide reserve capacity on long runs.
Braid
A line woven from multiple synthetic fibers, prized for near-zero stretch, thin diameter, and high strength.
Bullet weight
A cone-shaped sliding sinker used to rig soft plastics so they slip through cover cleanly.
Chum
Bait scattered in the water to attract fish to an area; regulated or prohibited in some places.
Drag
The reel mechanism that lets line slip under tension so a running fish doesn't snap the line.
Drop-shot
A finesse rig with the weight below the hook, suspending a bait just off the bottom.
FG knot
A slim, strong knot for joining braided line to a fluorocarbon or mono leader; passes easily through rod guides.
Fluorocarbon
A dense line material with a refractive index close to water, making it hard for fish to see; it also sinks and resists abrasion.
Jighead
A weighted hook, often paired with a soft plastic, used for bottom-contact and finesse presentations.
Leader
A length of line tied between the main line and the lure to add stealth, abrasion resistance, or shock strength.
Line memory
A line's tendency to hold the coiled shape of the spool, causing tangles; worst in stiff or cold line.
Monofilament
A single-strand nylon line that stretches and floats; forgiving, inexpensive, and easy to tie.
Ned rig
A finesse technique using a small soft-plastic stick bait on a light mushroom jighead.
Polarization
A lens filter that blocks horizontally reflected light, cutting surface glare so you can see into the water.
Pound test
The rated breaking strength of a line, expressed in pounds; higher test means thicker, stronger line.
Rotomolded
A one-piece molding process used for premium coolers, producing thick, seamless, highly insulated walls.
Shock strength
A line's ability to absorb sudden force, such as a hard strike or a headshake, without breaking.
Spinnerbait
A lure with spinning metal blades that flash and vibrate to draw reaction strikes while covering water.
Split shot
A small round sinker pinched onto the line for quick, adjustable weight changes.
Swivel
A small connector that rotates freely to prevent line twist, often used with spinning lures or leaders.
Terminal tackle
The hardware at the business end of your line — hooks, weights, swivels, snaps, and beads.
Topwater
Lures fished on the surface, producing visual strikes; best in low light and calm conditions.
UPF
Ultraviolet Protection Factor — how much UV a fabric blocks. UPF 50+ blocks roughly 98 percent of UV.
