Choosing between two fish finders for marine electronics sonar navigation usually comes down to two questions: how much sonar detail do you want on the screen, and how much are you willing to spend? The Humminbird 597ci 597 HD Fish Finder sonar is the more feature-dense option; the Garmin Fishfinder 160C Marine Boat Echo Sounder Sonar Fish Finder is the more affordable route. Both are new-other units, so the real work is matching the feature set to the type of fishing you do.
Quick verdict
If you want a fuller picture of what is below the boat, the Humminbird 597ci 597 HD is the stronger pick. Its richer feature set makes it easier to read structure and hold your position. If you want to spend less and keep the setup straightforward, the Garmin Fishfinder 160C is a capable marine boat echo sounder sonar fish finder with a lower listed price.

Product notes
Humminbird 597ci 597 HD Fish Finder sonar

The Humminbird 597ci 597 HD is the more expensive of these two units, but it also gives you a longer list of reasons to choose it. The color display and chart plotting help you keep position and structure in view, while side scanning gives you a wider look at what is below the boat. Add a depth alarm, depth indicator, temperature reading, Fish ID, sonar recording, expandable memory, and a waterproof housing, and you have a complete system with transducer. The limitation is straightforward: you pay a higher price upfront, and the feature set is aimed at people who want a multi-function screen rather than a bare-bones echo sounder.
Garmin Fishfinder 160C Marine Boat Echo Sounder Sonar Fish Finder

The Garmin Fishfinder 160C is the pick when you want to keep the initial cost down. Its price is lower than the Humminbird's, and it is identified as a marine boat echo sounder sonar fish finder with the manufacturer part number FISHFINDER 160C. The Country of Origin is Taiwan, and the unit is a new-other product. That makes it a direct choice for a shopper who wants a sonar unit without a long feature menu. The limitation is that the feature details are not spelled out in the same way they are for the Humminbird; if you want chart plotting and side scanning called out, the Garmin's details are more compact and leave that comparison to you.
Final choice by use case
Choose the Humminbird 597ci 597 HD if you want the more feature-dense unit and are comfortable paying for it. It suits anglers who want a system with transducer and a fuller dashboard view.
Choose the Garmin Fishfinder 160C Marine Boat Echo Sounder Sonar Fish Finder if you prefer a simpler sonar unit with compact details and you are comfortable making the call based on the product type and part number.
