The stainless steel probes are available in 3 sizes: 7-, 9-, and 12-inch.
The Air2HP is a hand-held aerifier that is ideal for hard to reach places such as around tree roots, sand bunkers, flower beds or where ever else you may need to spot treat. It accomplishes the same job as the Air2G2, however, it only uses a single probe and an external air supply is required for use (there is a port on the Air2G2 compressor that the Air2HP can be connected to). Pressurized air is injected into the soil at a diameter of 3 feet and up to 40 inches deep with the Air2HP.
The Air2G2 is an easily operated, self-propelled aerifier that uses only three probes to inject pressurized air directly into the ground. By doing this, it is fracturing the compaction layer of soil without causing any damage or disruption to the surface of the soil. This machine can be used in any weather (rain or shine) and it does not require any post aerification cleanup, meaning the turf can be played on immediately, saving you time and money!
