Privacy Notice

AV Assistant requests and retains your unit, ID, address, and contact information.  Your location, check location, and your test location are used to provide you with a localized map and location-based data (aids to navigation) from the U.S. Coast Guard Light List and Local Notice to Mariners.  Your photos are used to document observed discrepancies with aids to navigation. Your voice recordings are saved to assist you in documenting observed discrepancies. This information is compiled into a report that is sent only to the email address(es) you provide. No data is transmitted to the developer other than what Apple provides in crash data reports and app services.


  • An iPhone or iPad running iOS 11 or later is required to run AV Assistant.
  • To use AVA for USCG or USCG Auxiliary aids verification, you must have GPS. iPhones and iPads with WiFi+cellular have GPS. WiFi-only iPads lack the GPS hardware, so you must add this capability through a plug-in or Bluetooth GPS module.
  • If you are buying a device for AVA, the cheapest recommended option is an iPad Standard (9.7″) with 128GB and WiFi/Cellular for $559. It is not necessary to install a SIM card or activate cellular service to use the GPS. An iPad Mini or Air is only slightly more.
  • Alternatively, you can get a WiFi-only iPad and buy the external GPS to use with it. A bit more cumbersome but you get WAAS GPS, which is a little more accurate.
