The Pieps IProbe II is a next generation avalanche probe! Its particularly suitable for beginners in the avalanche rescue area as well as for courses and is available in two lengths. Whats special about this drop sensor is that a sensor is activated as soon as its assembled. Its placed on the tip and transmits a signal to the LED light as soon as you hit an obstacle while youre probing. Theres also an acoustic signal. For all those who are having trouble with probing and knowing whether they have found a buried person are therefore provided with more time and its safer for the buried person as well! Another advantage of this technology is the fact that, in this case, the electronic probe transmits a signal to a close by beacon by Pieps which is IProbe-compatible which deactivates the search in progress so that your comrades can keep searching for other buried people by following the next closest signal. The probe has contrasting colors and a scale for easier orientation in addition to that. Theres a strap on the handle that allows for connecting the segments. Due to the transmitters reach of 50 cm the searching area is increased by this length electronically. If its defective, the probe also works mechanically, just as any other probe. It can work for around 150 hours with an AA battery.
