Garmin Striker Vivid 4cv review

ClearVu is Garmin's scanning sonar mode that renders bottom structure in near photographic detail, distinct from the traditional CHIRP arches the base Striker 4 draws. The Vivid 4cv pairs both modes with the vivid color palette Garmin introduced across the Vivid line, and ships with the GT20-TM transducer that reads both traditional CHIRP and ClearVu, where the plain Striker 4 ships with a transducer limited to traditional CHIRP only.

The Vivid 4cv also carries an internal GPS, so waypoints, a boat speed readout and Garmin Quickdraw Contours mapping come standard rather than as an upsell.

The 4cv is the cheapest way into ClearVu, but it is not the only way. The table below lines up every screen size Garmin sells with ClearVu against the price gap.

Four inches is workable for one sonar view at a time. Split it between CHIRP traditional on one side and ClearVu on the other, which is the whole reason to buy this unit, and each half is a little over 2 inches wide. Structure that would read clearly as a brush pile on a 7 inch split screen becomes a smudge you have to squint at on the 4cv.

Cone coverage makes the shallow water case more visible. A narrow CHIRP cone near 20 degrees, typical of an entry level 200 kHz beam, covers a circle about 3.5 feet across in 10 feet of water, using 2 times depth times the tangent of half the cone angle. That narrow a window is exactly why the ClearVu half of the split screen matters on a small boat in skinny water, and exactly why that half is cramped on a 4 inch panel.

Anyone who reads the section above and pictures a cramped screen should look one size up. The Striker Vivid 5cv adds a full inch of diagonal for about $150 more, and owners of both units consistently describe the jump from 4 to 5 inches as the one that made a split screen usable rather than merely possible. The Striker Vivid 7cv steps up further to 7 inches while keeping the same CHIRP and ClearVu sonar, with no side imaging added. Budget conscious buyers who do not need ClearVu at all can drop back to the plain Striker 4 and put the $60 difference toward a better mount instead.

The Vivid 4cv draws a small enough current that most trolling motor batteries or a dedicated 12 volt tap handle it without a second thought, and the GT20-TM mounts on a transom exactly like any other skimmer transducer. The full installation sequence, including where to drill and how to aim the transducer, is covered in the fish finder installation guide linked below rather than repeated here.

This is the right unit for a small boat or jon boat where console space is the actual binding constraint, not the budget, and where CHIRP traditional was already enough except for the one time a school of fish sat over cover the traditional view could not separate from the bottom. It is the wrong unit for anyone planning to add a second screen, a trolling motor integration, or GPS mapping deeper than basic Quickdraw Contours, all of which point toward an ECHOMAP instead.
