Choosing between two Garmin chartplotters for marine electronics sonar navigation comes down to a $70 price spread and a trade-off in condition. The Garmin GPSMAP 440S lists at USD 279.99 in used condition, while the Garmin GPSmap 545s lists at USD 349.99 as new-other. One comes with a suncover and mount; the other appears never to have been installed. Here is how to pick between them.
Quick verdict
If you want the lower listed price and need the mount, suncover, and power cord included, the Garmin GPSMAP 440S is the practical choice despite its used condition. If you prefer an uninstalled unit with cables still zip-tied and the fishfinder name in the title, the Garmin GPSmap 545s justifies the higher listed price.
Price and condition at a glance
| Product | Listed Price | Condition | Price Level | Highlights |
|---|---|---|---|---|
| Garmin GPSMAP 440S Marine Boat GPS Chartplotter With Suncover With Mount | USD 279.99 | Used | Suncover, mount, power cord included | |
| Garmin GPSmap 545s Marine Boat GPS Chartplotter Fishfinder | USD 349.99 | New other (see details) | Cables zip-tied, no box |
Where the GPSMAP 440S wins
The 440S is the lower-priced listing of the two, and it includes a suncover, a mount, and a power cord. The 545s, by contrast, is listed as unit and cables only. If you are equipping a boat that needs a ready-to-mount unit, those inclusions help offset the used condition. The unit has been cleaned, and the country of origin is the United States.
Where the GPSmap 545s wins
The 545s is listed as new-other, and it does not appear to have been installed, with cables still zip-tied to the unit. For buyers who want a unit that was never mounted, that is the stronger condition story. The title also explicitly adds fishfinder to the chartplotter designation, which may matter if you want sonar and GPS in one display. The trade-offs are the higher listed price and the lack of a box.
Product notes
Garmin GPSMAP 440S Marine Boat GPS Chartplotter With Suncover With Mount
This used Garmin chartplotter sits at the lower end of the pair's price spread. It includes a suncover, a mount, and a power cord, so the basic pieces needed to install and protect the unit are accounted for. It has been cleaned, and the manufacturer part number GPSmap 440S confirms it is a Garmin product. One thing to weigh: the title points to a chartplotter rather than a fishfinder, so if sonar display is a priority, the 545s title is more explicit about that capability.
Garmin GPSmap 545s Marine Boat GPS Chartplotter Fishfinder
The pricier option in this pairing is listed as new-other. It does not appear to have been installed, and the cables are still zip-tied to the unit, suggesting it stayed in its original packaging state apart from the missing box. A few cover scratches are noted, but the unit overall is in very good condition. If you want the fishfinder label in the product name and an uninstalled example, this is the one to buy. The downside: no box is included, and the $70 price spread over the 440S is the difference you will weigh.
Final choice by use case
- For a tighter boat-buying budget: choose the Garmin GPSMAP 440S with the included suncover, mount, and power cord.
- For an uninstalled unit with the fishfinder designation: choose the Garmin GPSmap 545s in new-other condition.
Both remain GPSmap-family chartplotters, so the decision is really about condition, included accessories, and whether the extra cost of the 545s is worth the differences.
