The tMA(+) thermal monocular adapter allows the tM 35, tM 35.2 and tM 35+ to be very easily converted from a hand-held device to a clip-on device. Together with your SWAROVSKI OPTIK rifle scope, the thermal imaging device creates a powerful combination that requires no sighting in and guarantees a 100% reliable point of impact – each and every time. The various tMA(+) thermal monocular adapters are compatible with all current SWAROVSKI OPTIK riflescopes, except the X5i series.
