The LUCKY Portable Fish Finder FFC1108 and the GARMIN Fishfinder Depth Finder 80 both locate fish and read depth, but they're built for different kinds of fishing. Here's the head-to-head.
Quick verdict
Pick the LUCKY FFC1108 when you want a fishfinder you can carry with you. Pick the GARMIN 80 when you want a Garmin sonar designed for boat fishing.

Product notes
LUCKY Portable Fish Finder FFC1108

The LUCKY is a portable/handheld fish finder with a 2-inch LCD screen that includes a backlight, and its transducer sends a 45-degree, 200kHz beam down to 328 feet. That combination makes it easy to check depth from a kayak, a dock, or an ice-fishing setup. The unit runs on four AAA alkaline batteries; the battery life is 8 hours. The main limitation is that those batteries are not included, so have them ready before your first trip. It's a portable tool by design, which means you get sonar in a small handheld package.
GARMIN Fishfinder Depth Finder 80

The GARMIN 80 is the more boat-oriented option. It's a marine boat sonar, has sonar sensors, and comes in a durable plastic housing. One practical feature is the dual measurement system: it reads in both Decimal and Imperial units, which is helpful if you switch between unit types. The clear limitation is condition-this unit is Used, so it's not a New in Box purchase like the LUCKY. If you're comfortable with a pre-owned Garmin and want a marine sonar for a boat, this model is the one that points in that direction.
Final choice by use case
- Kayak or ice fishing: LUCKY FFC1108. The handheld design fits spots where you don't have a console.
- Boat anglers who want Garmin: GARMIN 80 at USD 65.00.
- Lower price: LUCKY FFC1108 at USD 39.45.
