When you shop for marine electronics sonar navigation, the first question isn't which brand is best; it's where do you fish. A kayak or shoreline session calls for a unit you can carry, while a boat with a console can handle a dedicated echo sounder. That's exactly the fork in the road between these two fish finders.
Quick Verdict
Two very different sonar tools are on the table. The Portable Handheld Fish Finder is the grab-and-go solution for kayak, dock, and ice fishing, while the Garmin Fishfinder 160C is a marine echo sounder designed for a permanent boat installation. Your boat situation will decide which one is worth the price.

Product Notes
Portable Handheld Fish Finder

If you fish from a kayak, a dock, or through the ice, this handheld unit keeps the sonar with you. The LCD display with LED backlight is readable in dim conditions, and the transducer reports depth and fish size. The 4-5 hour battery life covers a typical outing, and the neck strap lets you keep it close while paddling. The yellow casing and compact build make it easy to spot in a tackle bag. The catch is that it's built as a portable, self-contained device rather than a permanent mount. That's the trade-off for its compact size and mobility.
Garmin Fishfinder 160C

For boat owners who want a dedicated sonar on the console, the Garmin Fishfinder 160C is a marine echo sounder with the Garmin name and a specific manufacturer part number. It's listed in new other condition, making it a straightforward choice for a fixed installation. If you're ready to wire a sounder into your boat's dash, this Garmin gives you a clean path to do that. The limitation is that it's meant to be a boat unit; if you mostly fish from shore or a kayak, the mounting and power requirements of a marine sounder don't fit your setup as easily. This is a tool for the boat-centric angler.
Final Choice by Use Case
If you fish from a kayak, dock, or the shoreline, the Portable Handheld Fish Finder at $77.91 is the match: its LCD backlit display and 4-5 hour battery give you sonar without a permanent mount. If you have a boat and want a Garmin marine echo sounder built into your electronics rig, the Garmin Fishfinder 160C at $175.00 is the unit for that job. The $97.09 difference simply reflects how each unit solves a different part of the fishing puzzle.
