Sharpen your observation skills with the HELIOSHERE© Solar Timepiece field kit to connect with the seasonal variations in solar time. Your local solar time is displayed as a pattern of light on the transparent dial-face of the HELIOSPHERE© sundial.
Engage with some basic principles of navigation and time as the app walks you through the set up to align your timepiece with True North and your latitude.
