Garmin ECHOMAP UHD2 93sv review
Quick answer
The Garmin ECHOMAP UHD2 93sv costs $1,299.99 and pairs a 9 inch diagonal screen, a 7.8 by 4.5 inch actual display, with a GT56 transducer. Garmin's own housing dimensions run 10.4 by 6.5 by 3.2 inches, which means the console cutout is bigger than most small boats already have cut.
The Garmin ECHOMAP UHD2 93sv is the largest screen in the standard UHD2 line, at $1,299.99, and the first model in that line to trade the GT54 transducer for the higher resolution GT56. Nine inches of diagonal glass sounds like a lot of chartplotter until the actual display dimensions are measured against a console cutout.
This review is built from Garmin's own published dimensions and sonar specifications for the 93sv, plus the recurring themes in verified owner reviews. The screen size math below comes directly from Garmin's listed measurements.

Nine inches is the diagonal, not the width
Garmin's own listing states the 93sv's overall unit dimensions as 10.4 by 6.5 by 3.2 inches, with a display size of 7.8 by 4.5 inches inside that 9 inch diagonal figure. That is the standard geometry of a 16 by 9 widescreen: the diagonal measurement is always larger than either the width or the height taken alone, and a console cutout has to clear the full unit housing, not just the visible glass. A buyer measuring an existing hole with a tape and expecting a 9 inch screen to mean a 9 inch wide opening will come up short.
Published dimensions across the UHD2 line
Screen size numbers get confusing fast once diagonal, display size and housing dimensions are all in play. Garmin publishes exact figures for the 93sv; the smaller screens follow the same widescreen ratio.
The 9 inch diagonal screen on the 93sv measures 7.8 by 4.5 inches of actual display, inside a 10.4 by 6.5 by 3.2 inch housing.
Published figure A published engineering, regulatory or manufacturer figure. It does not change because somebody disagrees with it.
| Measurement | Figure |
|---|---|
| Screen size, diagonal | 9.0 in |
| Display size, width x height | 7.8 in x 4.5 in |
| Overall unit dimensions | 10.4 in x 6.5 in x 3.2 in |
| Transducer included | GT56-TM |
Figures are Garmin's own published dimensions for the ECHOMAP UHD2 93sv, not a measurement taken from a physical unit.
What the 9 inches costs you
Price nearly triples the entry level Vivid 4cv, and the cutout required to flush mount a 10.4 by 6.5 inch housing does not exist on most small boat consoles built before this screen size became common. Owners upgrading from a 7 inch unit frequently report needing to enlarge or replace the console panel entirely, not just cut a slightly bigger hole, because the mounting flange and cable routing behind the glass both need more depth than a 7 inch install left available.
Budget pick and the step up most consoles cannot fit
Buyers who like everything about the 93sv except the price and the cutout should look at the ECHOMAP UHD2 73sv, which keeps the same cartography and a nearly identical feature set on a 7 inch screen for $300 less. Buyers chasing even more usable screen area, enough to run a live sonar view, side imaging and a chart at once without any of them feeling cramped, should look at the ECHOMAP Ultra 2 126sv, a 12 inch unit that will not fit most small boat consoles without a real refit, and is not a reasonable step up for anyone who has not already confirmed the space exists.
93sv against the size below and the size most people cannot fit
| Specification | Garmin ECHOMAP UHD2 93sv | Garmin ECHOMAP UHD2 73sv | Garmin ECHOMAP Ultra 2 126sv |
|---|---|---|---|
| Price | $1,299.99 | $999.99 | $2,899.99 |
| Screen size | 9 in | 7 in | 12 in |
| Transducer included | GT56 | GT54 | not published |
| Cartography | Garmin Navionics Plus US Inland | Garmin Navionics Plus US Inland | not published |
| Touchscreen | Yes | Yes | not published |
Every figure above is the manufacturer own published specification. Where a maker does not publish a figure the cell reads "not published" rather than carrying an estimate, because on ratings and currents an estimate that reads as a specification is a safety problem rather than a gap.
Who the 93sv actually fits
This is the right screen for a boat with a console already built around a 9 inch or larger cutout, or a bow mount install where the housing depth is not fighting rod lockers and wiring behind the panel. It is the wrong screen for anyone retrofitting a small boat built around a 5 or 7 inch factory hole, where the 73sv delivers nearly the same feature set without a console rebuild.
How we chose
We did not test this equipment in person and we never claim to. Picks are researched from manufacturer specification sheets, published engineering and regulatory figures, and the recurring themes in verified owner reviews. Every pick is matched to a real thrust rating, a real published amp draw, a real capacity or a real conductor size rather than to a price bracket, and it is placed in the tier where its published capability actually belongs. We rejected the unbranded flood that dominates several of these search results, because a lithium pack whose management board is the only thing between a cell fault and a fire, a breaker protecting a battery cable, a life jacket and a bracket holding a two thousand dollar motor to the bow at highway speed are all parts whose failure has a consequence nobody can walk away from. Where a figure is convention rather than a published standard we label it that way, and where a manufacturer does not publish a figure we leave it out instead of estimating it.

Frequently asked questions
How big is the actual screen on the ECHOMAP UHD2 93sv?
Garmin's published listing states a display size of 7.8 by 4.5 inches inside the 9 inch diagonal measurement. The 9 inch figure describes the corner to corner distance across the glass, not the width or height on their own, which is standard for any widescreen display and not unique to this unit.
What size cutout does the 93sv need?
Garmin's overall unit dimensions are 10.4 by 6.5 by 3.2 inches, which sets the minimum housing depth and footprint a console needs behind the panel. The visible cutout itself is close to but slightly smaller than those housing dimensions, and buyers should confirm the exact cutout template from Garmin's installation instructions before cutting a console panel.
What is the difference between the GT54 and GT56 transducers?
Garmin markets the GT56 as its ultra high definition transducer, included with the 93sv, versus the GT54 included with the smaller 63sv and 73sv. Garmin's published listings describe the difference qualitatively as sharper ClearVu and SideVu imaging, without stating a specific resolution number that would let buyers compare the two transducers on a single measurable spec.
Can the ECHOMAP UHD2 93sv run LiveScope?
Yes. Like the 73sv, the 93sv is built with a port and processing capacity intended for Garmin LiveScope, sold separately as the GLS 10 black box and a compatible transducer. The larger screen makes a live sonar view genuinely usable alongside a chart and traditional sonar, which is one reason some buyers choose the 93sv specifically to run LiveScope.
Is the ECHOMAP UHD2 93sv worth the price over the 73sv?
It depends on console space and whether the GT56 transducer's sharper imaging matters more than $300. Buyers with the room for a 9 inch cutout and a use for the larger screen, such as running live sonar alongside a chart, get real value from the 93sv. Buyers without a 9 inch cutout already available get most of the same feature set from the 73sv for less.
Does the 93sv include Garmin Navionics+ charts?
Yes, the version reviewed here ships with Garmin Navionics+ US Inland cartography preloaded, covering lakes and rivers rather than coastal tidal water. Garmin also sells other ECHOMAP UHD2 93 series configurations with different cartography regions, so buyers should confirm which chart region ships with the specific listing they are purchasing.

Researched, not professional advice. This page is compiled from published engineering and regulatory figures, manufacturer specifications and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are boating convention rather than published standards, and they are labelled that way wherever they appear. Marine electrical work is not house wiring. Use tinned, finely stranded marine cable, size it for voltage drop and for the ABYC E-11 ampacity table rather than one or the other, and put overcurrent protection within seven inches of the battery positive terminal, because everything between the post and the fuse is unprotected. A lithium battery needs a charger with a lithium profile. Never load a boat past its capacity plate, and remember that canoes and kayaks carry no federal capacity plate at all, so their stated capacity is the manufacturer own figure. Wear the life jacket, and treat early season water as the hazard it is: cold water immersion takes your breath and then your hands long before it takes your core.
