It sounds like they don't have their own translation.

Which translation of the Bible does the Gideons International distribute?
Depending on the language, the most currently accepted translation in the language of the print. As a Gideon since 1994, I have distributed thousands of free New Testament versions and placed hundreds of hotel Bibles. Until recently, the New King James Bible (NKJV) was the most common version in English. It is acceptable to 55% of English speakers, the next highest is the NIV with 19%.

Gideons International, an organization that places Bibles in hotels and hospitals, at one stage used the NKJV translation along with the KJV, offering the KJV as the default translation and offering the NKJV when an organization asked for a Bible in newer English to be used. After HarperCollins' acquisition of Thomas Nelson, however, the Gideons have chosen to start using the English Standard Version (ESV) instead of the NKJV.[10][11]
