What's with the heated regulator though?
The regulator is heated because the 100m shoots are in- / outdoors where there is no heating, so very cold in jan/feb/mar.
The HW100 regulator performs very bad under 10 deg C, so that is why I built in a heating element, powered by an external battery to tackle that issue. It works very well, clearly better groups under 10 degr C.
