The camera is good; not sure I needed this length, since you can't really force it once it hits a snag about 60 feet in. The markings on the cable are very light and hard to see. The sonder is a drag. You have to practically be a sonar/radar technician to distinguish the sounds to locate the camera head, even right in front of you. Just a confusing setup. This unit is a sliver of the price of a pro setup, so having just the camera feature is well worth the price. If the sonder is an additional cost, adding it on is debatable. But if you have more than one house to video, it's a great value. You'll eventually need one of these; it's an ace in the pocket
