Garmin Striker Vivid 4cv vs 5cv: which fishfinder is the smarter buy?

Display

Winner: Product B

The Striker 5cv wins the display battle because it has a larger 5-inch screen versus the 4-inch display on the Vivid 4cv. In practice, that extra inch matters more than it sounds: split-screen sonar views are easier to read, fish arches are less cramped, and the whole interface feels less fiddly when you’re peering at it in bright daylight or from a small boat. The Vivid 4cv does have Garmin’s Vivid colour palettes, which can improve target separation and make returns easier to interpret, but the smaller screen is still the limiting factor. If you’re plotting carp at range, checking drop-offs for pike, or scanning over a mark for bass, the 5cv is simply more comfortable to use.

Performance

Winner: Product B

Both units are Garmin fishfinders and both are designed to be straightforward rather than intimidating, but the 5cv has the stronger feature set. It includes CHIRP Traditional and ClearVu scanning sonar plus built-in Quickdraw Contours mapping software, while the 4cv offers Vivid scanning sonar colour palettes and the same general Garmin ease of use. For anglers on UK waters, Quickdraw is a genuine advantage: you can build your own contour maps on club lakes, gravel pits, reservoirs and unfamiliar stretches of river, which is brilliant for finding shelves, holes and isolated features. The 4cv is perfectly capable for basic fish finding, but the 5cv is the better tool if you want to understand a venue rather than just look for fish.

Build quality and design

Winner: Tie

Garmin’s Striker range has a strong reputation for being rugged and practical, and neither of these units feels like a compromise in terms of build quality. Both are compact, boat-friendly designs aimed at straightforward installation and reliable day-to-day use. The 4cv is the more compact unit, so it suits cramped setups, small inflatables, kayaks or a minimalist bank/boat arrangement. The 5cv is larger, but that extra size is part of the point: it gives you a better interface and more readable data. On pure build quality, there is no meaningful loser here; the difference is design intent rather than durability.

Battery life

Winner: Tie

Neither product listing provides a battery specification here, and in real-world use battery life is usually driven more by your power source, screen brightness and sonar use than by the model name alone. Because the 5cv has the larger screen, it may draw a little more power in identical conditions, but that’s not enough to call a decisive winner from the information available. If you’re running a small battery on a kayak or portable setup, the 4cv’s smaller screen could be a slight advantage, but not a game-changer. For most anglers, battery life is essentially a tie.

Price and value for money

Winner: Product A

This is where the decision becomes much clearer. The Vivid 4cv is £206.48, while the 5cv is £440.41, a huge difference of £233.93. That price gap is hard to ignore because both are Garmin units with solid reviews: the 4cv has 4.6/5 from 3,035 reviews, while the 5cv has 4.5/5 from 1,088 reviews. If you want a reliable sonar unit for finding fish without paying for mapping and a bigger screen, the 4cv is far better value. You’re getting most of the core fishing benefit for less than half the price.

Game library/features

Winner: Product B

Fishfinders don’t have a game library, so the meaningful comparison here is feature depth. The 5cv wins because it has GPS and built-in Quickdraw Contours mapping software, which are proper angling features rather than nice extras. GPS is useful for saving waypoints, returning to productive marks, and building a repeatable approach on lakes, rivers and coastal marks. Quickdraw is particularly valuable for UK anglers who fish pressured carp waters, mark-rich pike venues or shifting sea bass ground where the bottom changes and local knowledge matters. The 4cv’s Vivid colour palettes are useful and user-friendly, but they do not match the practical advantage of GPS mapping.

Overall user experience

Winner: Product B for serious anglers, Product A for simplicity

The 4cv is the easier, cheaper, less intimidating option. It is ideal if you want a clean, no-nonsense fishfinder that helps you see fish and structure without spending a fortune. The 5cv is the better overall fishing tool because the bigger screen, GPS and Quickdraw mapping make it more versatile and informative, especially on waters you don’t know well. If you fish regularly and want to build a proper picture of the venue, the 5cv feels like a more complete angling companion. If you just want to turn up, switch on and start fishing, the 4cv is the more sensible buy.

Overall summary: Product B is the better fishfinder and the one to buy if you want the most capable, future-proof option. Product A is the better value and the smarter choice for anglers who mainly want dependable sonar at a much lower price. For most serious UK anglers, the 5cv wins on usefulness; for budget-conscious buyers, the 4cv wins on value.
