    I wanted to get advice on getting a thermal imager for upcoming trips. I cannot afford most thermal imagers. I wanted to ask if anyone has experience with the Seek Thermal Imager Pro for the iPhone. If I cannot afford a regular thermal imager, is it worth getting that?

    Also, has anyone ever rented out an old thermal imager that they don’t use anymore?

    Just trying to think of feasible ways to get one ahead of my upcoming trips.
