It purchased at the same time as compact level for equipment. It is 100 points if a magnet is attached with this size, but I think that this is a good product. Since there is work which is troublesome with a magnet, I think that it will not get in the way even if putting it in a waist bag of a small and lightweight safe belt (such as a place where there are many packers and iron powder). I think that COSPA is good, but it may be unsuitable for exact horizontal leveling. I think that it is recommended for sub-divisions.
