Reel size should match your target species and rod power. Smaller reels (1000-2500) work best for light freshwater fishing with panfish and trout. Medium reels (3000-4000) handle bass, walleye, and light saltwater. Larger reels (5000+) are designed for heavy saltwater, pike, and catfish. Check your rod's recommended reel weight range for optimal balance and performance.

Saltwater reels feature corrosion-resistant materials (stainless steel, anodized aluminum) and sealed drag systems to withstand harsh salt environments. Freshwater reels use standard materials and are lighter. Never use a freshwater reel in saltwater—salt will corrode internal components and cause failure. If you fish both, invest in dedicated reels for each environment or choose a quality saltwater reel that works in both.

Gear ratio (e.g., 5.1:1) indicates how many times the spool rotates per handle turn. Higher ratios (6.0+) retrieve line faster—ideal for topwater, crankbaits, and covering water quickly. Lower ratios (4.5-5.0) provide more power for heavy lures and deep presentations. Match your ratio to your fishing style: fast ratios for reaction baits, slower for power fishing and deep water.

Rinse your reel with fresh water after each use, especially in saltwater. Store in a cool, dry place and apply reel oil to moving parts monthly. Drag systems (friction-based) control line release under pressure. Set drag to 1/4 of your line's breaking strength for optimal performance. Check drag regularly—it should slip smoothly when pulled hard. Professional servicing every 1-2 years keeps your reel performing like new.
