What the AI looks for in Fish Finders & Depth Finders

Sonar types
Traditional CHIRP for depth and arches, down imaging for structure detail, side imaging to search wide, forward-facing for live targeting Each sonar type answers a different question, and features are priced by which ones are included.
Transducer included and mount
Check that the included transducer supports every advertised sonar mode and mounts on your transom, trolling motor or kayak Many units advertise features that need a different or extra transducer.
Screen size
Around 5 inches is the minimum for split-screen; 7 inches or larger if you will run side imaging next to maps Split views on small screens become unreadable.
Mapping
Decide whether you need built-in lake and coastal charts or GPS waypoints only Mapping is the main jump from a fish finder to a combo chartplotter.

Brands that matter

  • Garmin: Striker for value, ECHOMAP and LiveScope for higher tiers.
  • Humminbird: Helix and Solix, known for strong side imaging and lake maps.
  • Lowrance: Elite and HDS lines in the Navico ecosystem.
  • Deeper: Castable sonar for shore and dock anglers using a phone.

What to avoid

  • Assuming the included transducer supports every advertised sonar mode
  • Buying a small unit when you need split-screen side imaging
  • Mixing transducer brands; connectors are proprietary

Questions

Fish finder or combo?

A combo adds a GPS chartplotter with maps. If you fish unfamiliar or large water, the mapping is worth it.
