Let me preface all this by saying, "I am partnered with Freefall Data Systems as a dealer and will financially benefit if you purchase this from me."
Now lets get into the truth. ITS A GAME CHANGER for me. The FDS ColorAlti G2 is both an audible altimeter that you're used to and as close to a Heads Up Display for altitude that we have on the current skydiving market. Similar to how some audibles like FDS SonoAlti G2V can keep you constantly altitude aware by speaking the altitude the ColorAlti G2 gives you a constant indication of your given altitude based on an LED light in your field of view. It retails for $379 and is available through my website's store here: ClarkeAirSports.Squaresite.com.
