Release Notes:

Read me first! 

  • This is a major software update, therefore the update process may take longer than previous versions – please be patient.
  • After Flex NX is updated, reboot manually before attempting to update a satellite antenna.
  • Please ensure that satellite antennas are powered off before attempting to update Flex NX.

 New Product Release:  

  • We have released the new Flex LT system (https://www.geophysical.com/products/flex-lt)! Flex LT and Flex NX share the same software environment, so future Flex System Updates will update both systems with a single update package.  

New Features 

  • New collection mode: 2D Remote Control (for Flex NX and wirelessly connected satellite antennas only). This is an enhanced version of Screen Mirroring that broadcasts the full Flex NX 2D Collection Screen to a Wi-Fi enabled mobile device, providing access to the complete left flyout menus (Gain, Display, and Depth), Start/Stop Scan, Screengrab, Fast Forward, and Delete. Note: Target Tagging is not available in 2D Remote Control. 

 For guidance on using 2D Remote Control please refer to the latest Flex NX Quick Start Guide (https://www.geophysical.com/support/flexnxsupport).  

Use this feature with Flex NX, or with a paired and active NX15 or NX25 satellite antenna. Try 2D Remote Control using a tablet for a larger viewing screen, or a smart phone for a lighter and more portable display. Flex NX must remain powered on when using 2D Remote Control. However, as long as you are within 65 feet (20 meters) of Flex NX you can scan with a satellite antenna and mobile device without bringing Flex NX with you. This is especially useful when scanning on scaffolding or ladders, or in other dangerous, elevated, or confined situations. Additionally, use this feature to capture full UI screengrabs with your mobile device. 

  • Tap to Hide. During data collection, simply tap the Flex NX or Flex LT screen once to hide the on-screen menus and controls (Top Navigation Menu, Left Flyout Menu, and lower Control Bar). Tap the screen again to bring back the menus. This feature is also available in when using 2D Remote Control on a mobile device. 

 Feature Improvements 

  • Display Gain: Auto Gain. Implemented an auto gain feature and improved performance of Gain Slider and Gain Regions. 
  • Flex Mode: Voxel export [Flex NX only]. When transferring projects containing Flex Mode scans, Flex NX now transfers a Flex Mode .BIN file containing a voxel model.  
  • Flex Mode: Improved Depth and Gain [Flex NX only]. Increased depth range of Flex Mode from 30cm (12in) to 68cm (27in), and improved depth-based gain for Flex Mode. 
  • Project Transfer: .FSN file. Enabled export of .FSN file to optimize the import of Flex NX data into GSSI Fusion. Simply transfer the .FSN file to a USB drive or mobile device, then upload the .FSN file to GSSI Fusion. This will create a new GSSI Fusion project with the organizational structure from Flex NX, including Project Results organized by Area of Interest.

 Miscellaneous Improvements 

  • Improvements to system stability added on 02/27/2025
  • Improved aspect ratio persistence when zooming data with Width Scaling applied. 
  • Adjusting dielectric during collection no longer affects Display Gain. 
  • Improved text string translations for various languages. 

 File Compatibility Notice 

  • This software update is not backwards compatible with Flex Mode scans collected using Nexus Software Version 1.582 (the previously released software version). As a result, Flex Mode scans from software version 1.582 cannot be opened in Playback Mode. We expect this to be temporary, and we hope to provide a fix in the near future.
