How Do I Upgrade?

  • ReefMaster 2 installs "side by side" with ReefMaster v1, with a new 14 day trial period. ReefMaster 2 can be downloaded here.
  • If you have an existing ReefMaster v1 installation, please ensure that this is updated to the latest version (1.8.41 or later) before installing ReefMaster 2.
  • Existing ReefMaster v1 users can upgrade to ReefMaster 2 for US$50 (+ VAT, where applicable). Any existing additional modules are retained across the upgrade process, and ReefMaster 1 can continue to be used in parallel if required.
  • The upgrade to ReefMaster 2 can be purchased via an in-app Upgrade button, if an existing ReefMaster v1 key is present.
  • For new users, the price of ReefMaster 2 is now US$199 + VAT.
  • The ReefMaster LITE edition has been discontinued, and ReefMaster 2 loses the PRO designation to become simply “ReefMaster”.

 What is the ReefMaster Upgrade Policy?

  • All minor version upgrades, X.x to X.x+1, are free.
  • Major-version upgrades are not free, but upgrade costs are significantly less than the cost of a new license.
  • Major-version upgrades are planned to happen every few years, with a large number of minor-version updates in between. Minor-version updates (over 30 during the lifetime of the ReefMaster v1 release cycle) can contain bug fixes as well as significant functional upgrades.
  • Planned updates as part of the ReefMaster 2 release cycle include; GeoTiff support (import and export), XTF file format support, automatic edge (bottom) detection in sonar files, vegetation mapping and more.
