The GoBible Traveler's interactive on-screen menu allows the user to easily scroll through the Old and New Testaments and select the book and chapter where the user wants to begin play. Additionally, the user has the option of following the GoBible Traveler's "Bible-in-a-Year" plan for listening to the entire Bible in 365 days. Lastly, the GoBible Traveler can support 36 Bookmarks so the user can mark their favorite chapters or where they left off listening. The GoBible Traveler is operated with one AAA battery that can power the device for over 20 hours depending on backlight timer use, which is adjustable.
