Those will go through much tougher ground than a vibrating plough, but they're also much slower and you can see the trench when it's done. With the plough, we'd typically go through the gravel berm along the road and you'd have a hard time telling that it had just buried the cable even if you were looking for it!
Our fiber ISP, Ting, used those in our neighborhood to lay new lines. It was interesting to watch. For the most part, the only place where you could see any disturbance was when they had to pop up for a junction box.
Generally looking at around $200,000 for one of those. They work great in certain areas. If you’re doing urban work like we are they’re not so great because there’s a utility every 10 feet.
