Answer 1 - The main requirement is a location on sand, near a beach. Clay, shale, sandy loam and other ground matter are not able to facilitate use of sand spear. If a neighbour uses a sand spear less than 6 metres, it is likely that you, too, will be able to use a sand spear, although sand spears can vary in depth, quality and quantity between nearby sites.
