Trying to add portable sonar without overhauling your boat? In tacklecurrent fish finders boat electronics, the choice often comes down to a pocket-size depth checker versus a full portable kit with a larger screen and transducer. That is exactly the tension here: one option keeps cost and size minimal, the other brings a bigger display and a rated 600 ft depth capability with included mounting hardware.
Quick verdict
If you want the lowest listed price and a super-compact unit for occasional depth checks from a kayak, canoe, or dock, the Portable Digital Fish Finder Sonar Depth Sounder at USD 24.99 is the straightforward pick. If you want a larger 4-inch grayscale LCD, 168x132 pixel resolution, and a complete portable system with transducer, cables, and manual included, the Eagle Cuda 168 Portable Fish Finder Sonar at USD 106.78 is the more capable setup - with a listed price spread of $81.79 between them.

Product notes
Portable Digital Fish Finder Sonar Depth Sounder NEW Open Box Excellent NEW Cond
This is the minimalist approach to portable sonar. The listing describes it as NEW Open Box in Excellent NEW Cond, with Color Black and Country of Origin China, and the attributes point to a very small 48 × 64 pixel display measuring 1.5 " X 1.8'. You get a Depth Indicator feature for Outdoor use and a listed 6 hr battery life, which suits quick checks from a small boat or bank fishing rather than all-day charting. A reason to choose it is the USD 24.99 listed price, the lowest in this comparison, paired with that ultra-compact form factor. A limitation is the small screen and lower resolution, plus the description does not detail a transducer, temperature reading, or fish ID functions that the competing kit lists explicitly.
Eagle Cuda 168 Portable Fish Finder Sonar w/ Transducer Manual
This is a turnkey portable system. The description states open box, never used, with original box, manual, portable base, transducer, cables, suction cup/mounting accessories, and an extra LEI transducer bracket - the exact item shown. The 4 in display at 168x132 pixels, grayscale screen, fish ID, water temperature reading, and 200 kHz Skimmer transducer give you more on-screen information, and the attributes list Maximum Depth 600 ft with Measurement System Decimal & Imperial and Power Source Batteries. A reason to choose it is that completeness: you are not sourcing a transducer or mount separately. A limitation is the higher USD 106.78 listed price and larger overall kit to transport and store, and the box shows shelf wear from storage even though the unit and accessories are described as unused.
Final choice by use case
- Choose the Portable Digital Fish Finder Sonar Depth Sounder if you fish occasionally from a kayak, canoe, or small boat and want the smallest, lowest-priced way to confirm depth. The USD 24.99 listing and 6 hr battery life make it easy to toss in a tackle bag for short outings.
- Choose the Eagle Cuda 168 Portable Fish Finder Sonar if you want a dedicated portable fish finder with a 4 in 168x132 pixel display, fish ID, temperature, and a 600 ft depth rating, plus the included 200 kHz Skimmer transducer and mounting accessories for flexible boat setups.
Both are listed as New other (see details) and for Outdoor use, so condition is comparable. Decide on screen size and kit completeness versus compact simplicity - and let the $81.79 listed price spread guide how much capability you need on the water.
