Ice Fishing Electronics

Understanding flashers, sonar, and underwater cameras to find and catch more fish.

Flashers vs. Sonar

The two main types of ice fishing electronics:

Flashers: Display real-time information on a circular dial. Excellent for jigging because they show fish and lure movement instantly. Industry standard for serious ice anglers.

LCD Sonar: Similar to open-water fish finders. Show a scrolling history which some find easier to interpret. Modern units rival flashers in speed.

Pro Tips

  • Flashers have a learning curve but excel for active jigging
  • Many anglers prefer flashers for their real-time response
  • Some units offer both flasher and sonar modes

Underwater Cameras

Cameras let you see exactly what's happening below the ice:

  • Identify species before you catch them
  • Watch fish reactions to your presentation
  • Learn structure and bottom composition
  • Great for entertainment and teaching kids

Cameras complement electronics but don't replace them - you can't watch a camera while actively jigging.

Battery Management

Cold weather drains batteries quickly:

  • Use lithium batteries designed for cold weather
  • Keep batteries inside your shelter when possible
  • Bring backup power for long trips
  • Let electronics adjust to cold slowly to prevent condensation

Important

  • Cold batteries provide less power - always bring backups
  • Store electronics at room temperature between trips
