Surgeons, plumbers, mechanics – they all need an inside view of hard-to-reach places where their eyeballs can’t reach. You’ve probably seen endoscopic cameras on TV, the ones that look like skinny snakes with light bulbs for eyes. But instead of feeding on mice, these cameras feed images back to their users. And they offer a view behind whatever is blocking the view of what you need to work on.

These cameras have come a long way in recent years. For proof, just look at this new arrival to the Cult of Mac Store. It’s a sleek, slithering camera fitted with an HD camera, waterproof sealing, LED lights, even WiFi. And right now, you can get a WiFi HD Waterproof Endoscopic Camera for just $32.99.

Whether you’ve got a clogged drain or engine trouble, it pays to see exactly where and what the problem is. And after all, eyeballs are limited when it comes to pipes and deep chambers where no light can reach. This handy endoscopic camera creates a way through, with an 8-way adjustable LED and a waterproof 2 megapixel camera. You can slip it between the cracks to get at whatever you need a view on, and get a realtime feed right back to whatever device you’re using via WiFi.
