The biggest, and perhaps most important difference with the Race Plate Zoom Compass from Silva is the size of the baseplate. By making it significantly smaller it fits better in the user’s hand. It also has a smaller capsule which significantly reduces the risk of bubbles. Another difference is with the stencil holes. They are withdrawn from the baseplate and put in a separate “scale and stencil hole” plastic card that comes together with the compass. Everything to keep the compass as clean as possible. They changed the needle design to increase the map visibility and with a Jet needle, it means that it’s extremely fast and stable which is great when you need to make quick decisions during a race. The rubber feet beneath the compass means better map contact and minimum risk of slipping.
