AWD-40PS is a variant of seismic source of the “weight drop” type. The hammer is equipped with an inclined platform, allowing it to be installed at an angle of 45 degrees, and a special stop, adding stability in an upright position, what allows to perform survey on shear waves.
The source AWD-40PS is mounted on a compact lightweight frame equipped with reliable wheel blocks. The delivery package of the source includes one hammer: 20, 33 or 40 kg.

The total weight of the source without battery pack is less than 120 kg. The energy of a single impact reaches 1000 J.
The source can be mounted on a trailer, trunk of a pickup, a four-wheeler or a compact wheel pair (tow bar — four-square).
