FAQ: Garmin Echomap Ultra 102sv With Gt56uhd-tm

  • The built-in sonar of the ECHOMAP units you’re considering is sufficient for your depth range, so using a black box for deeper capabilities is unnecessary.
  • The ECHOMAP Ultra 102sv has a built-in sonar and side scan, which is adequate for most fishing needs, especially in the specified depth range.
  • For speeds and depths as mentioned, the GT56 transducer is excellent, but for higher speeds, an in-hull or thru-hull transducer could be advantageous.
  • If you often go offshore, it’s recommended to have a unit capable of radar and AIS.
  • ECHOMAP units are more suited for lake and bass boats, whereas offshore boats might benefit from units with more comprehensive features like radar, weather, etc.
  • Units like the GPSMAP 943xsv or 1243xsv offer full MFD capability (radar, weather, etc.) at a lower price than the 86xx xsv series.
  • The GPSMap 8616xsv has a faster processor and better sonar capabilities, but it might be overkill for your needs if you don’t require advanced features like 1KW dual channel sonar.
  • The ECHOMAP Ultra units should suffice for most fishing and navigation requirements, especially in shallower waters.
  • It’s important to consider future-proofing your setup. Don’t compromise on technology, as better electronics can add value to your boat.
  • The choice of transducers is critical, especially if you fish both inshore and offshore. A combination of UHD GT56 for shallow waters and a B175L or M for deeper waters can be effective.
  • The type of boat and its intended use play a significant role in deciding the appropriate electronics. For offshore capable boats, more advanced systems are recommended.
  • The ECHOMAP Ultra 102sv is a good fit for shallow water activities like freediving.
  • However, for an offshore capable boat, even if used occasionally for offshore trips, it’s advisable to consider units capable of integrating radar and other advanced features.
Yes, having a dedicated screen for side scanning can be beneficial, especially for locating diveable bottoms in shallow waters. The ECHOMAP Ultra 102sv with the GT56UHD-TM Transducer is capable of providing detailed side-view images, making it a good choice for this purpose.
  • The Ultra models (102 or 106) offer a higher resolution (1280×800) compared to the 1022’s 1024×600, which can be significant for Livescope use.
  • Ultra models are touchscreen, while the 1022 is not. This could be a crucial factor depending on your preference for interface interaction.
  • The Ultra can take screenshots and record on an SD card, a feature that may not be available on the 1022.
  • If you plan to integrate with other Garmin units in the future, the Ultra models would be a better choice as the GPSMAP 1022 will only network with other GPSMAP units.
  • The 1022 can record screen video to your phone, a feature that might appeal to some users.
  • However, it only displays video output and cannot run a transducer like the Ultra models.
  • The 1022 is wider, which might be a consideration if you plan to use it in a mobile Livescope system.
  • It can network with other GPS map units but not with the Ultra or ECHOMAP UHD models.
  • The resolution difference in Livescope between the 93 UHD and 106 Ultra is not substantial.
  • The 106 has better resolution and processing speed than the 93 UHD, but it also consumes more battery and is heavier, which might be a drawback for ice fishing.
  • The 1022 is user-friendly with its dials, making it a viable option for Livescope if networking with other units is not required.
  • It’s also important to note that the 1022 has a video output, which can be useful for connecting to a TV, especially for ice fishing in an ice castle.
  • For Livescope use, the difference between these models isn’t significant, except in portable ice fishing situations where the 93 might be more suitable due to its lighter weight.
  • The 93 UHD models might offer better value, especially with potential fire sale pricing and compatibility with Livescope.
  • Ultimately, the choice depends on specific needs like resolution, portability, battery consumption, and the desire to network with other units.


The Garmin ECHOMAP Ultra 102sv is a high-end marine chartplotter/sonar combo and sonar system designed for serious anglers and maritime enthusiasts. It features a high-resolution WXGA, IPS touchscreen, sonar capabilities like CHIRP traditional sonar, ClearVü, and SideVü scanning, GPS and navigation with a 10 Hz receiver, and compatibility with NMEA 2000 and NMEA 0183.
