FLIR\’s range of handheld thermal imaging cameras for maritime safety and security purposes starts with the very budget sensitive Scout TK and runs from there through its more capable Ocean Scout 280, Ocean Scout 320 and very high resolution Ocean Scout 640 siblings. For security purposes we sell the FLIR LS-R and FLIR LS-X hardened models. For extended use with low operator fatigue we recommend the binocular-style BHM Series.
