FLIR V Guide?
Neither, get a Pulsar Helion XQ38F
Because of ITAR regulations, none of the FLIR thermals available in the UK can refresh the image faster than 9 times per second (9Hz) - that makes moving the device or watching moving targets produce a very jerky image. You need at least 25Hz refresh rate to get smooth video
Guide thermals are just vastly over priced for what they are.
