The Core Difference: GPS vs Screen Size
Everything else between these two fish finders is relatively minor. The real decision comes down to one question:
Do you need GPS and waypoint marking?
The Garmin Striker 4 has a built-in GPS. The Lowrance HOOK2 4x does not.
If you want to mark fishing spots, record productive locations, and navigate back to specific waypoints — the Garmin Striker 4 is your fish finder. It’s worth the extra $40.
If GPS doesn’t matter to you and you want the biggest screen for the lowest price — the Lowrance HOOK2 4x gives you a larger display for $40 less.
That’s the decision in plain English. Everything below is detail.
Garmin Striker 4 — Full Review
Price: ~$139
The Garmin Striker 4 is the fish finder we recommend to most beginners — and the GPS is the primary reason why.
Key Features:
- Built-in GPS with waypoint mapping
- CHIRP sonar for cleaner, more detailed returns
- 3.5 inch color display
- Dual-beam transducer — 77/200kHz
- Flasher mode for ice fishing
- Portable kit available separately
The GPS changes how you fish. Mark a brush pile where you caught bass last weekend. Mark the edge of a weed flat where crappie were stacked. Mark the creek channel where catfish hold in summer. Come back next trip and find those exact spots in seconds — even on a featureless lake where everything looks the same from the surface.
For anglers who fish the same bodies of water repeatedly, waypoint marking has a compounding effect. Every trip adds more data. After a full season you have a map of every productive location on your home water — information that takes most anglers years to accumulate by memory alone.
CHIRP sonar (Compressed High Intensity Radar Pulse) sends a continuous sweep of frequencies rather than a single pulse. The result is a cleaner, more detailed sonar image that separates fish from structure more clearly than traditional single-frequency sonar. At this price point, CHIRP is a genuine advantage.
The 3.5 inch screen is the Striker 4’s weakest point compared to the HOOK2 4x. It’s smaller than the Lowrance display and can be harder to read in bright sunlight. Garmin addressed this with the Striker 4cv (a newer version with a slightly better display) but at the base Striker 4 price, screen size is the trade-off you make for GPS.
Ice fishing bonus: The Striker 4 includes a flasher mode — a circular display format used for ice fishing that shows fish approaching your bait in real time. If you ice fish at all, this is a meaningful bonus that the Lowrance HOOK2 4x doesn’t offer.
Bottom line: The better fish finder for most anglers. The GPS alone justifies the $40 price difference if you fish the same waters more than once.
Lowrance HOOK2 4x — Full Review
Price: ~$99
The Lowrance HOOK2 4x is the fish finder for anglers who want the most display for the least money — and don’t need GPS.
Key Features:
- 4 inch color display — larger than Garmin Striker 4
- Wide Angle CHIRP sonar
- Auto-tuning sonar — adjusts settings automatically
- Simple 3-button operation
- No GPS
The 4 inch screen is genuinely better than the Garmin’s 3.5 inch display for casual reading — easier to see fish arches, bottom composition, and depth. For anglers who just want to know where the fish are without navigating menus or managing waypoints, the larger screen makes daily use more pleasant.
Auto-tuning sonar is a legitimate advantage for beginners. The HOOK2 4x automatically adjusts sensitivity and frequency settings based on conditions — you don’t need to understand sonar theory to get a clean image. Power it on and it works. The Garmin Striker 4 requires more manual adjustment to get the best image in varying conditions.
Wide angle sonar covers more bottom area per pass than the Garmin’s dual-beam transducer. Useful for quickly scanning unfamiliar water to find fish-holding structure before settling in to fish.
The absence of GPS is the real limitation. You can still find fish with the HOOK2 4x — you just can’t mark where you found them with precision. On small ponds or familiar water with obvious landmarks, GPS matters less. On large lakes or featureless reservoirs, the inability to mark waypoints is a genuine handicap.
Bottom line: The right choice for budget-focused anglers fishing small, familiar water who want the simplest possible fish finder experience.
Side-by-Side: Which Situations Favor Each Unit
Choose the Garmin Striker 4 if:
- You fish large lakes or reservoirs where GPS navigation is useful
- You want to mark and return to productive fishing spots
- You ice fish (flasher mode is a real advantage)
- You’re willing to spend $40 more for meaningfully better long-term value
- You fish the same bodies of water repeatedly and want to build a waypoint library
Choose the Lowrance HOOK2 4x if:
- You fish small ponds or familiar water where GPS isn’t necessary
- Screen size matters more to you than GPS features
- You want the simplest possible setup with minimal menu navigation
- Budget is the primary concern and $99 is your ceiling
- You fish from a kayak or small boat where a compact, simple unit is preferable
What About the Garmin Striker 4cv?
The Striker 4cv is an upgraded version of the Striker 4 that adds ClearVü scanning sonar — a forward-looking sonar that produces a near-photographic image of structure beneath the boat.
Price: ~$179
If your budget stretches to $179, the Striker 4cv is worth serious consideration. ClearVü sonar is a meaningful upgrade that shows structure detail the standard Striker 4 simply can’t match. For anglers targeting bass around complex structure — laydowns, rock piles, bridge pilings — the ClearVü image changes how you fish those spots.
Our Verdict
For most anglers: Garmin Striker 4.
The GPS and waypoint mapping deliver value that compounds over time. Every productive spot you mark becomes permanent knowledge about your home water. The $40 price difference pays for itself the first time you return to a marked brush pile and catch fish instead of spending 30 minutes trying to relocate it by memory.
For pure budget buyers: Lowrance HOOK2 4x.
If $99 is your hard ceiling and GPS genuinely doesn’t matter for your fishing, the HOOK2 4x is a capable fish finder that won’t disappoint. The larger screen and auto-tuning sonar make it the most user-friendly option at this price.

Frequently Asked Questions
Is the Garmin Striker 4 worth the extra $40 over the Lowrance HOOK2 4x? For most anglers, yes. The built-in GPS and waypoint marking alone justify the price difference if you fish the same bodies of water more than once per season.
Can I use these fish finders on a kayak? Both work excellently on kayaks. The Lowrance HOOK2 4x is slightly more popular among kayak anglers due to its simpler operation and lower price. Both can be powered by a small 12V battery easily stored in a kayak hatch.
Do these fish finders work in saltwater? Both are rated for saltwater use. The transducers are sealed and corrosion resistant. Rinse with fresh water after saltwater exposure to extend the life of the transducer cable connections.
Which fish finder is easier to install? The Lowrance HOOK2 4x is marginally easier due to its auto-tuning sonar — no sensitivity adjustment required. Both units install in roughly the same time: 30-60 minutes for a basic transom mount installation.
What’s the difference between CHIRP and regular sonar? Traditional sonar fires a single frequency pulse. CHIRP sends a continuous sweep of multiple frequencies simultaneously, producing a more detailed, easier-to-read image with better target separation — distinguishing individual fish from structure more clearly.
