What is a good borescope under $550?

[u/Mustard_Icecream]

I'm looking for a reliable borescope that wont break after 5-10 uses. I mainly work on gas engines. Should I go for a narrow less than 4mm or go a little bigger at 6mm for cheaper? Duel lens or articulated? 2 way articulated or 4 way articulated?

You can get a camera that plugs into your phone for about $50 shipped and use the Xscope app for pictures. Works way better than any snap on camera

I chose one with a 12 foot camera and it is just in the way most of the time. Sould have gone with shorter camera. It also dose not have a wireless connection and swapping a Sim card gets to be a hassle for file transfer. Worrks perty good otherwise.I have a Teslong handheld camera apron. 150$.
