For people with vision impairment accurately reading a standard spirit level to determine levels when building or constructing can be challenging. Inaccuracy in determining the appropriate level can result in tasks being assembled or constructed wrongly which can be costly and lead to lower productivity.
A spirit level is available that emits a range of audible signals depending on the level, with no signal when completely level. The spirit level is battery operated (Vision Australia 2005 - 2006).
