Why is everybody against or at least not talking about air impacts. We all have a ready supply of air and as I mentioned earlier a HF air impact is actually cheaper than a torque multiplier. You have to add hose but honestly how much easier does anyone want it? The likelihood of a flat tire and a dead compressor is so small that everybody should be easily convinced to carry a big impact. Cuts changing a tire by at least 75% compared to the old armstrong technique. I just don't get it?
