Not really a f150 issue but you may find this info useful.
endoscope ypc hd720p bought this scope awhile back and it worked ok at first. Now, I wanted to use it again to try and find a valley pan coolant leak and wouldn't you know it does not work anymore. Cable connections too loose. Doesn't seem to want to charge. Dead as hell.
Waste of money would not buy again. Bought a different one PCE-VE 50 BORESCope and it works perfect and uses AA batteries that I can replace.
Plus, it's not WiFi like the other piece of junk.
Just a heads-up for those looking for a camera for your truck

 

 

I have one that plugs in my android phone. I think it was $20 on amazon. 6 yrs ago. Ive taken it all over world for work too....pretty simple...works ok. didnt work on coworkers Honor phone recently when he tried it though. Bright light, takes pics and video.

 

Borescopes are now dirt cheap on amazon. I picked one up a few months ago that has two cameras, a 5" screen, video and still pictures to sd card and has an internal rechargeable battery all for around $30.

 

Same here. I have one I grabbed off Amazon that connects to a large screen. Pretty nice picture and has a long cord.

Then I grabbed another from AliExpress that has one of the articulating heads on it. It connects to a Smartphone or Tablet with USB-C. Used it to peek into the cylinders of my 91 Hwanda and was able to view the valves with the articulating head.

Cool.

 

Which one is better and what exactly is it?
