Whats the difference between a GOOD thermal imager and a GREAT thermal imager.On the hill deer demo, we started off with the Flir PS24 and PS32 and although we struggled against the back ground to identify species at distance, we knew they were large animals as we could detect several large heat blobs, but couldn't tell (although we knew already) that they would have been red deer. No video output on the Flir's meant we couldnt capture this so may run an iphone attachment soon to show how these entry level models differ to the Quantum and the Guide. Switching to the Pulsar Quantum HD38S and Guide IR518EB (currently with a grand off RRP) the difference was instantly obvious, the structure, size and shape of the animal was evident and you could clearly pick the hinds from the group.We had also taken along our range topping Thermoteknix Ti Cam 750LR, which blew the testers away! General opinion was, which is backed up by popularity, that the Quantum HD38S at £2899 offers a huge improvement in performance over units costing £1500 to £2300 and the detail, definition and general performance at 500m was not THAT far away from the TiCam considering the Ti Cam, which is remarkable considering the TiCam starts at around £23,000.
The Quantum HD38s, on a personal opinion, is truly mind blowing in terms of performance it will detect the red deer heat source at nearly 1km away, and let you see antlers on the stags to define the males at half that distance.On the moor at night foxing, the Quantum offers a truly advantageous perspective to spotting foxes at night.
