good find- i've seen this kind of thing before -just using i truck with pressure plates - no dynamite-and even though the trucks i've seen are good sized they look like they are acceptable to drive on roads road-and no big problem if they arent
dont know what the date of the article is but i dont think they are the only ones using one just truck at a time
2. ONE SMALL LIGHTWEIGHT SEISMIC TRUCK: Our energy source truck is smaller and lighter than many other seismic trucks you may have seen. It is a short lightweight highway-legal truck with only one rear axle. This is not a giant truck with monster tires. Its small size means it has surprisingly low impact on the land. Ask to see pictures.
Also we only use one small truck rather than a convoy of several trucks.
3. HIGH FREQUENCY ENERGY SOURCE ON THE TRUCK: It’s not only that our truck is smaller than other seismic trucks. The energy source that is on the truck is also better. It transmits a higher percentage of its energy in high-frequency sound waves than previous generations of energy sources that are still used by many seismic contractors. We also have newer geophones that are better able to receive and record the reflections from these higher frequency transmissions.
Higher frequency waves mean higher resolution images.
All energy is created with the truck.
We do not drill shot holes and we do not use dynamite.
