All of the new models share some common features such as:

According to the company, the FLIR ThermoSight Pro PTS233 has a suggested retail price of $2,199. This unit is currently shipping and available for sale. The other two units, the FLIR ThermoSight Pro PTS533 and the FLIR ThermoSight Pro PTS733, are expected to ship in the fourth quarter of 2017. The company did not advise a suggested retail price for these units. While the prices may be out of the range of the casual hunter, they are well within the reach of many serious hobbyists and pro hunters.
