The ECHOMAP UHD2 is an upgrade from the previous ECHOMAP UHD series. Here are the key improvements introduced by Garmin in the UHD2 SV series:

  • Enhanced Screen Resolution: The UHD2 models boast almost double the screen resolution of the previous UHD models. They have a resolution of 1024 x 600 pixels compared to the 800 x 480 pixels of the older models, resulting in crisper and clearer images.
  • Faster Processor: The UHD2 features an upgraded, faster processor, which enhances overall performance. This includes quicker loading of maps, smoother scrolling, faster response to input, and improved clarity in sonar imaging.
  • New Firmware with Advanced Features: The UHD2 runs on new firmware based heavily on the GPSMAP units, giving it a more high-end feel and additional features. One highlighted feature is the ability to save presets for various settings, allowing quick adjustments based on water conditions or fishing methods.
  • Garmin Navionics Plus Mapping: The UHD2 comes with the new Garmin Navionics+ maps as opposed to LakeVu and BlueChart maps in UHD series. Navionincs+ offers more detailed mapping and a true Navionics experience.
  • Wireless Networking Capabilities: The UHD2 screens can wirelessly share data such as sonar readings, waypoints, charts, and user data with other UHD2 screens. However, it’s important to note that LiveScope data cannot be shared wirelessly and still requires a wired connection.
  • Improved Gimbal Mount: The UHD2 features a new gimbal bracket with a more secure locking mechanism, similar to the one found in the Garmin Ultra Series. This design enhancement addresses issues with the previous model where screens could pop out if not properly secured.
  • Power Cable Change: There’s a notable change in the power cables. The UHD2 uses a two-pin design compared to the four-pin design of the previous UHD models. This means users upgrading to UHD2 will need to rewire and use the new power cable provided with the unit.

Is it worth upgrading from UHD to UHD2? It depends on how much value you place on enhancements like improved screen resolution, faster performance, and advanced mapping capabilities. If these features align with your requirements, then an upgrade could be beneficial.


What is the difference between ECHOMAP 93SV vs 94SV?

The primary difference between the ECHOMAP 93SV and 94SV lies in their mapping content – Navionics+ inland mapping for the 93SV model and Navionics+ coastal mapping for the 94SV model. This distinction makes each model more tailored to specific environments – freshwater inland waters for the 93SV and coastal, marine waters for the 94SV. Otherwise, they share similar sonar, display, and connectivity features.

What are the mounting options for the ECHOMAP UHD2 9 SV display unit?

For the Garmin ECHOMAP UHD2 9 SV, there are several mounting options available, with the notable exception that the swivel base is not compatible with this model. Here are the primary options for mounting the display unit:

What is the best battery for Garmin ECHOMAP UHD2 93SV?

Choosing the best battery for the fish finder involves considering several factors based on its power requirements. The ECHOMAP UHD2 93SV requires a power input of 9 to 18 volts DC, with a typical current draw of 1.72 amps and a maximum current draw of 3.5 amps at 12 volts DC. Given these specifications, here are the key considerations for selecting an appropriate battery:

  • Voltage Compatibility: The battery must provide a stable voltage within the 9 to 18 Vdc range. Most marine electronics are designed to operate optimally with a 12-volt system, making a 12-volt battery a standard choice.
  • Ampere-hour (Ah) Rating: The Ah rating indicates how much current a battery can supply over a period of time. For the Garmin ECHOMAP UHD2 93sv, a battery with a higher Ah rating will last longer. Considering its maximum draw of 3.5 amps, a battery with a higher Ah rating (e.g., 20Ah or more) would ensure prolonged use, especially important for longer trips or extended usage.
  • Battery Type: Deep-cycle marine batteries are typically recommended for marine electronics due to their ability to be discharged and recharged many times. 
  • Size and Weight: Consider the physical space available and the weight you can accommodate on your boat. Lithium batteries, for instance, offer a significant weight advantage over traditional lead-acid batteries.
  • Durability and Resistance: Look for batteries designed for marine use, as they need to withstand harsh conditions like moisture, vibration, and temperature fluctuations.
  • Brand and Warranty: Choose a reputable brand and check the warranty and after-sales service, as these can be indicators of the battery’s quality and reliability.
