What would you do without a camera???
I don't own a camera. A few years back I toyed with the idea of purchasing one, but opted to purchase electronic leak detection equipment and it hasn't disappointed. With slab leaks {for those of us who live where basements are few and far between} it is an easy sell to locate a slab leak. If fact, there is no selling involved, it sells itself. People don't have to be talked into locating and repairing a slab leak.
But I don't think that it is as easy to sell a camera inspection. Once the stoppage is cleared, people are like, "thanks, if it backs up again, we'll call you to inspect it with the camera." In my opinion, a camera is a more difficult add-on to sell. I have had drain line stoppages where I was highly recommending a camera inspection and they didn't want to do it. I would say something like, "We should investigate this sewer line and locate the bad spot so it can be dug up and repaired." And they were not interested. Just my observation. Maybe others are skillful at selling camera inspections, but I wasn't.
So I could never justify spending $10,000 on that tool. I could not see a meaningful ROI {return on investment} whereas getting into elec. leak detection has been a real winner.
A friend of mine bought the mini or micro camera for $5,000 and he was dis-appointed. He wasn't selling sewer repairs and also, the push cable was not that stiff. Even though it had like 100' of push cable, he had trouble sending the head down sewer lines that far, because the push cable would tend to kink on him at around 50' or so and he was un-happy with that camera.
So I wisely stayed away from purchasing a camera.
