This camera is well worth the value. We purchased the Vevor 300' for a water line inspection. The line was 4" PVC material and had clean potable water inside. We had a flow issue and could not locate the block. We had to down pressure our main to inspect it but it was well worth that. With the added roller wheel included with the camera system we were able to push with ease the camera into the pipe until we found our problem. We were also able to locate the line inside the main with our locating equipment and trace out where we needed to dig up the problem. The picture below is a photo taken with a cell phone of the actual screen in the field.
