Pulsar Helion XP38 has been discontinued. Please visit the Helion 2 XP50 HELION XP 38 thermal imaging monoculars are based on IR sensor (uncooled microbolometer) technology, and are represented by a number of models featuring various frame rates, magnifications and lens diameters. These monoculars are designed for use both at night and in the daylight. They are also able to be used in inclement weather conditions (fog, smog, rain) and to see through obstacles hindering detection of targets (branches, tall grass, thick bushes etc.). Unlike image intensifier tube based night vision devices, Helion thermal imaging monoculars do not require an external source of light and are not affected by bright light exposure. These monoculars have a wide range of applications including hunting, observation & terrain orientation, search & rescue operations and more.
