The Fishtechy Proof Ball makes it quick and easy to accurately measure length, girth, and weight of fish. Simply take a picture or video of your fish next to the Proof Ball, upload it to the free app and you'll get accurate measurements in seconds. This minimizes fish-handling time, reducing overall stress on fish you release. The app automatically identifies your fish and generates a private digital journal and map of all your catches. A Fishtechy Catchcard can be customized to display the length (fork or tail), weight, species, and more where it can then be shared in a public or friends-only feed. Removes guesswork from catch-and-release measurements Simple to use and provides accurate length, girth, and weight Minimizes fish-handling time to reduce stress Pairs with a free app and automatically IDs species Generates a private digital journal and map of catches Customize a Catchcard to share photos of your fish
