At present, we have different types of high sensitivity geophone sensors with sensitivity up to 600.00V/m/s. Meantime, low frequency geophone 2Hz with sensitivity 260.00V/m/s is the most popular geophone.
In addition, geophone 5Hz is a new trend of oil and gas seismic investigation, and the single 5Hz geophone is increasingly applied to replace multi-geophone strings.
