Key Features and Specs to Evaluate

  • Transducer – Select CHIRP broadband or traditional sonar. Optimal frequencies range from 80 to 200 kHz depending on target species and depth.
  • Display – Consider size, resolution, brightness and ease of use. Touchscreen offers convenience but drains battery.
  • Sonar Coverage – Wider beam angles show more fish but with less target separation. Narrow beams provide focused scanning.
  • Depth Capability – Deeper range required for open offshore waters. Shallow students fine for small inland lakes.
  • Power Output – Measured in watts. Higher output gives better performance but eats battery life.
  • Connectivity – Bluetooth, WiFi, GPS and networking allow interfacing with apps and chart plotters.
  • Mapping – Built-in maps that store waypoints and tracking data help you locate fish hot spots.
  • Upgrades/Add-Ons – Look for capacity to expand via added accessories like transducers or software updates.

Proper Fish Finder Installation

For wired fish finders, follow these tips for easy hassle-free installation:

  • Transducer Mounting – In-hull shoots through boat floor. Transom mount attaches externally. Trolling mounts to motor.
  • Display Mounting – Ensure viewer accessibility and protection from weather.
  • Cable Routing – Run wires neatly along gunwales secured with cable clips to prevent tangled snags.
  • Power Connection – Use marine battery, or wire to electrical system with 80 amp in-line fuse.
  • Transducer and System Testing – Ensure unobstructed transducer view and interference-free operation before first voyage.

Portable wireless finders simply require attaching the transducer float and powering on the handheld display.

Mastering Use of Your Fish Finder

It takes practice to hone your fish finder reading skills. Follow these tips:

  • Learn Sonar Interpretation – Structure, bottom contour, bait balls, fish arches – understand what you’re seeing.
  • Use Waypoints – Drop waypoints at productive areas you want to return to later.
  • Adjust Settings – Alter sensitivity, noise rejection and frequency for clearer views as conditions change.
  • Watch Your Speed – Excess speed causes scattered disjointed readings. For clarity go slow – under 4mph.
  • Identify False Signals – Waves, boat wakes, structure can show as false fish. Learn to discriminate real targets.
  • Update Software – Regularly install new software and maps to enhance performance and tracking.

Patience and repeated use develops fish finder proficiency. It’s a game of pattern recognition and interpretation.

Caring For Your Fish Finder

Protect your investment with proper care and storage:

  • Clean Transducer – Avoid fouling with anti-fouling treatments. Gently clean face with fine sandpaper.
  • Fresh Batteries – For portable finders, install fresh alkaline or lithium batteries before each trip.
  • Protect Wiring – Weatherproof wires and connections to avoid corrosion.
  • Gently Clean Display – Use microfiber cloth to gently wipe screen. Avoid harsh cleaners.
  • Store Properly Off-Season – Detach transducer and electronics, clean and store in cool, dry place during winter.

Routine maintenance preserves performance and longevity season after season.


Can fish finders work at high speed for trolling?

Higher speeds scatter sonar beams, but select CHIRP broadband models can effectively scan up to 8-10 mph for trolling speeds. Reduce speed for optimal resolution.

What’s the maximum depth capacity of most fish finders?

Entry-level portable finders reach around 100 feet. Advanced fish finders with higher power and wider frequencies can scan from 1000-1500+ feet deep.

Are expensive professional fish finders worth the investment?

For casual anglers, affordable entry models should suffice. Devoted serious fishing enthusiasts find premium features and enhanced performance worthwhile.

How long does a quality fish finder typically last?

With proper care, expect around 5 years from mid-range models, and over 10 years lifespan for high-end finders.

Can you use fish finders fishing from shore?

Yes, many portable wireless castable fish finder models allow fishing from shore, docks and bridges. Just ensure adequate depth and distance from shore.
