The PKI 5225 Handheld Thermal Imaging System is a highly effective device for all-hour observation and is intended to carry out search and rescue operations, evidence searching, hidden burial detection, night patrolling, concealed observation and tracking, mass events securing, environment protection etc. The PKI 5225 System has a shock-proof plastic rubber coated shell with ribbed surface and is safe against external actions. It provides a high resolution binocular eyepiece and not required interorbital distance correction. The PKI 5225 Handheld Thermal Imaging System operates with two buttons and optical encoder. The objective is protected by metal lens hood which can be easily removed for fastening of 2x optical adapter (extender).
