Choosing marine electronics sonar navigation gear is less about finding one universal screen and more about deciding which role matters most on your boat: a lower-priced legacy sonar/GPS unit, a feature-specific fishfinder-chartplotter, or a Garmin MFD identified by a particular model number. All four options are used, but their listed prices and stated equipment details point to very different buying cases.
Quick take
- Pick the Raymarine E70534 Element 9HV when CHIRP sonar, personal sonar mapping, charting options, keypad control, and NMEA2000 networking are priorities.
- Choose the Lowrance LCX-19C Legacy Marine Sonar And GPS Chartplotter for the lowest listed price and a legacy Lowrance sonar/GPS chartplotter.
- Consider either Garmin GPSMAP 4212 or Garmin GPSMAP 4210 when the exact Garmin model designation matters and the stated tested-working condition is appealing.
- The listed range runs from USD 160.00 to USD 799.99, so decide early whether expanded stated features or the lower initial price is the stronger fit.

| Lowrance LCX-19C Legacy Marine Sonar And GPS Chartplotter | Lowrance | Used | USD 160.00 | |
| Garmin GPSMap 4212 MFD w/ Sun Cover Boat Marine GPS Chartplotter Tested Working | Garmin | Used | USD 799.99 | |
| Garmin GPSMap 4210 MFD w/ Sun Cover Boat Marine GPS Chartplotter Tested Working | Garmin | Used | USD 799.99 |
Decision matrix
Choose by primary need:
- Sonar and charting tools: Raymarine Element 9 HV is the clearest match, with CHIRP sonar, GPS chartplotting, Navionics and C-MAP support, RealBathy, Navionics SonarCharts Live, and NMEA2000 named in its description.
- Lowest listed price: Lowrance LCX-19C is the clear choice at USD 160.00. Its title positions it as a legacy marine sonar and GPS chartplotter.
- A specific Garmin MFD reference: The Garmin pair share a listed price, used condition, sun-cover wording in their titles, and tested-working wording. The practical split is the 4212 versus 4210 model and manufacturer-part-number designation.
- Accessory expectations: Both Garmin descriptions explicitly exclude cables, cards, and mounts. That constraint should be part of choosing either Garmin model.
Product notes
Raymarine E70534 Element 9HV Boat Marine FishFinder CHIRP Sonar GPS Chartplotter
The Element 9 HV is the most feature-specific choice in this group. Its description names CHIRP sonar, GPS chartplotting, Navionics and C-MAP regional charting options, user-programmable keys, dedicated keypad controls, NMEA2000 networking, RealBathy personal sonar mapping, and Navionics SonarCharts Live. That combination makes the Raymarine the strongest fit for a boater focused on stated sonar mapping and onboard network integration rather than a basic legacy unit. The limitation is that E70534 is used, and its listed price sits much nearer the Garmin MFD pair than the Lowrance LCX-19C. Choose it for the stated sonar-and-charting tool set.
Lowrance LCX-19C Legacy Marine Sonar And GPS Chartplotter
The Lowrance LCX-19C makes sense when a legacy Lowrance sonar and GPS chartplotter is the target and keeping the listed price low is the leading concern. At USD 160.00, it occupies a distinctly different price position from the other three units. The description characterizes the LCX-19C as a marine navigation and chartplotting device with sonar and GPS functionality, while its title clearly identifies the legacy model. Its important limitation is condition: it is used, and cosmetic wear is specifically described. This is the straightforward selection for the shopper who wants the LCX-19C model and accepts a used unit with visible age-related wear.
Garmin GPSMap 4212 MFD w/ Sun Cover Boat Marine GPS Chartplotter Tested Working
Choose the Garmin GPSMAP 4212 when the GPSMAP 4212 model number and manufacturer part number 4212 are the identifiers you want. The title includes a sun cover and tested-working wording, while the description calls it pre-owned, in good shape, and subject to normal wear from use, age, and storage. It is a focused MFD choice rather than the feature-led Raymarine route. The major constraint is clearly stated: cables, cards, and mounts are not included. That makes the 4212 best suited to a buyer selecting this exact Garmin model designation and accounting for the excluded accessories.
Garmin GPSMap 4210 MFD w/ Sun Cover Boat Marine GPS Chartplotter Tested Working
The Garmin GPSMAP 4210 is the parallel choice for shoppers seeking manufacturer part number 4210 rather than 4212. Like its companion model, its title includes a sun cover and tested-working wording, and the description says it is pre-owned, in good shape, with normal wear from use, age, and storage. The 4210 also lists Taiwan as its country of origin. Its limitation mirrors the 4212: no cables, cards, or mounts are included. Pick this Garmin when the 4210 designation is your preferred reference; otherwise, the listed information does not establish a feature advantage over the 4212.
Final recommendation by use case
For the broadest stated mix of sonar, charting, mapping, controls, and networking, choose the Raymarine Element 9 HV. For the lowest listed-price route to a legacy marine sonar and GPS chartplotter, choose the Lowrance LCX-19C. Select the Garmin GPSMAP 4212 or GPSMAP 4210 when that exact model designation is the deciding factor, with the shared exclusion of cables, cards, and mounts built into the decision.
