Freefall Data Systems LLC launched two brand new skydiving altimeters on December 18, 2017. SonoAlti an audible altimeter that can be set using Bluetooth® wireless technology. ColorAlti is a patent-pending reconception of the peripheral vision LED altimeter. It can also be set using a free app called FDS Altis that is available on Apple’s App Store or Google Play.
SonoAlti was conceived to remedy the classic problem many jumpers have of trying to set—or remember how to set—their audible altimeters. It has three different types of alarms (ascent, freefall, and canopy) and up to eight of each type can be set. The volume of each type of alarm can be set individually and the user can select from a sound bank of 64 different alarms. The unit is always on and has a rechargeable lithium polymer battery with a life of approximately 200 jumps or three months. Although it is not its primary function, SonoAlti also includes a speed tracker feature, which allows the user to get real-time feedback during a jump of vertical descent speed via beeps. In addition, SonoAlti tracks jump numbers as well as freefall and canopy time. Using the app, one can obtain information about the last recorded jump and view altitude and vertical speed graphs (up to seven minutes of data). These graphs can be saved as photos to the user’s mobile device.
For ColorAlti, Freefall Data Systems LLC took the idea of peripheral vision altitude awareness and started from scratch. Unlike Elemental Technologies’ now defunct Chroma, ColorAlti contains a color LED, enabling it to display up to 256 different colors. The altimeter can be used in two different modes: continuous and discrete. In continuous mode, the light on the altimeter gradually blends through the colors of the rainbow according to two altitudes and colors of the user’s choice. In discrete mode, the light abruptly shifts to user-defined colors at altitudes of the user’s choosing. Up to eight of these discrete alerts can be programmed for ascent, freefall, and canopy. The unit has a flexible yet rigid gooseneck housing that is able to stay in place even at very high freefall speeds.
