When it comes to marine electronics sonar navigation, the big question is often whether you need a dedicated boat sonar or a handheld unit you can take anywhere. The Garmin Fishfinder 160C is a marine boat echo sounder, while the Portable Fish Depth Finder is a compact handheld. Both exist to help you find fish and understand the bottom terrain, but they clearly serve different workflows.
Quick Verdict
If you want a sonar that comes from Garmin and carries a clear product identity, the Garmin Fishfinder 160C is the one to put on your boat. If you want a battery-operated handheld with a fish alarm that you can bring along on a kayak, the Portable Fish Depth Finder is the better match.

Where Each Wins
The Garmin Fishfinder 160C shines as a dedicated boat sonar. It comes with a manufacturer part number and a listed country of origin, so you know exactly which unit you're getting. That kind of specificity is helpful when you're sourcing a sonar for a boat.
The Portable Fish Depth Finder counters with a 2-inch display, a maximum depth rating of 328 feet, and five sensitivity levels. The battery-save mode extends runtime, and the neck strap adds convenience. Those features make it a handy companion for kayak and small-boat anglers.
Product Notes
Garmin Fishfinder 160C
The Garmin Fishfinder 160C is a boat sonar designed for boat electronics and navigation. It carries a Garmin manufacturer part number and a country of origin spec, which gives it a straightforward identity for anyone looking for a specific sonar model. This unit is sold as new open-box, so you're getting a new product that may have had its box opened. The practical limitation of this listing is the 'new other' condition: it's not a factory-sealed package, so if you prefer an untouched retail box, that's a consideration. If you're okay with open-box status and want a dedicated boat sonar from Garmin, this is a clean choice.
Portable Fish Depth Finder
The Portable Fish Depth Finder is a handheld unit with a 2-inch display, a 328-foot maximum depth reading, and a fish alarm that alerts you when fish or schools of fish are nearby. It runs on battery power, offers five sensitivity levels, and has a battery-save mode to extend operating time. The neck strap and one-handed design make it practical for kayak or boat use. The limitation is the small 2-inch screen, which means you won't get the large sonar view of a bigger display. For a portable depth finder, that compactness is often the point, but anglers who want a wide screen may find it limiting.
Final Choice
If you want a dedicated boat sonar from Garmin and the $175 price fits your budget, choose the Garmin Fishfinder 160C. If you'd rather spend $85.99 and want a handheld that you can use on a kayak or boat, the Portable Fish Depth Finder is the one to take with you.
