Two very different answers to the same question-where are the fish? When you compare marine electronics sonar navigation options, one choice is a complete sonar system with its own display. The other is a castable bobber that uses your smart phone as the screen. Their listed prices span $59.99 to $252.00, so the decision depends on both budget and fishing style.
Quick Verdict
Choose the Humminbird 597ci 597 HD if you want a comprehensive unit with its own display and a full sonar package. Choose the HawkEye FISHPOD 5X if you want a portable fish finder that works with your phone and costs substantially less. Both models list a color display and a depth alarm, so the tie-breaker is how and where you fish.

Where Each Product Stands Out
- Humminbird 597ci 597 HD: The full-system pick. Its listed capabilities include chart plotting, side scanning, and expandable memory, giving it the navigation edge for boat-focused anglers.
- HawkEye FISHPOD 5X: The carry-everywhere pick. Bluetooth pairing, a depth indicator, and a 1-lb listed weight make it easy to bring along on shore, paddle gear, or ice trips.
Product Notes
Humminbird 597ci 597 HD Fish Finder sonar

Choose the Humminbird when you want a dedicated unit rather than a phone-based tool. It is listed as a system with transducer and includes a color display, depth alarm, temperature reading, expandable memory, plus chart plotting and side scanning. The trade-off is price and portability: it carries the higher listed price of the pair, and it is not the castable pocket-size style. If you fish mostly from a boat and want a full sonar unit ready each trip rather than a gadget you deploy from shore or a kayak, this is the stronger buy. The feature list points to a more complete navigation setup, not a quick-answer tool.
HawkEye FISHPOD 5X Bluetooth Wireless Castable Smart Phone Fish Finder

Choose the FISHPOD if you want sonar that travels with you. The listing describes a castable, pocket-size bobber that pairs over Bluetooth with your smart phone, which becomes the screen. A depth indicator and a 1-lb listed weight keep it practical for quick checks from a boat, kayak, paddle gear, shore, or an ice hole. It also lists a waterproof build, so damp conditions are less of a concern. The trade-off is scope: it is designed for quick fish-finding and depth work rather than the wider navigation role of the Humminbird. If you want a compact companion for your phone, this red castable model is the one to take.
Final Call by Use Case
- Boat trips with room for a full system: Humminbird 597ci 597 HD, the higher-priced full sonar system.
- Shore, kayak, paddleboard, or ice fishing: HawkEye FISHPOD 5X, the take-anywhere smart phone fish finder.
- When you are torn between the two: let your on-water routine and the price difference decide.
