SonarInk

SonarInk app allows you to view your GPS/Fishfinder screen on an android tablet with a black & white e-ink screen type, like the popular e-readers with a screen visible under direct sunlight. SonarInk app is compatible with Simrad/Lowrance GPS/Fishfinders with a built-in WiFi connection, and runs on android tablets with e-ink screens.

Instructions: First connect your tablet to your GPS/Fishfinder WiFi, then attempt to run the app. Press the V# button repeatedly to select video frame refresh rate, varying from V0 (full video) to V5 (video snapshot every 5 sec). Pressing this button repeatedly cycles through all available choices. Press the camera button to take a full colour snapshot of your display and save it into the tablet's memory.

The ability to view a snapshot of the streaming screen video, every so many seconds, works perfectly for e-ink type of screens that have a long refresh rate and thus cannot display streaming video properly. On the other hand e-ink type of screens, unlike regular colour tablet screens, are perfectly visible under direct sunlight.

Notes: SonarInk app is currently compatible with Simrad / Lowrance GPS/Fishfinders that have built in WiFi screen repeater capabilities, and work with the Gofree app. For running on a e-ink screen equipped smartphone or tablet the system should support Android Version 4.2.2 (Jelly Bean) and above. The app has been tested successfully on the following e-ink tablets that run on android 4.2.2 (separate purchase required):
