Had an issue with a blocked pipe that got snaked out and then blocked up again. The camera on this unit is very good and I was able to send the camera snake down to see damage in the pipe. The camera does NOT self level so you have to pay attention to how it rolls in the pipe so you know which way is up and left and right. The video record and picture record is great and the removable micro SD car makes it easier to take the video to your PC and look at it on a large screen.
The 512mhz locator/detector is not as good as the video system. Following the directions it's more than likely not directly underneath where the locator believes it to be. The battery door is not very sturdy and can come undone and the batteries fall out while you are working.
Overall it's a handy system and very easy to get a visual assessment of areas you can't reach normally, but the locator system is a bit hit and miss.
