Learning how to use your camera system is easy. Learning how to use the locator will take time.
Learning how to use a video pipe inspection system is easy. You just plug it in, turn it on and push it down the drain. So now you're looking at a broken pipe or a root obstruction. But, if you don't know where it is, you don't know where to dig. Now comes the tough part - locating.
Some camera systems have footage counters so you know approximately how much push rod you've got in the line. And if the line is straight as an arrow, that might help a little. But if the pipe drops down 10 feet, makes a 90 to the right, goes 20 feet, and then makes another 90 to the left before it heads toward the septic tank, you could end up digging up some unhappy customer's rose garden when you should have dug near the willow tree.
