1 Problem: Combro 625 is made from transparent dark or blue plastic. Because during the day the sun light outside is much more stronger then diode light inside (also in the shadows) -> measuring doesn't work (work only inside) .... to correct this problem you need to cover upper part with black tape.
2 Problem: Mechanically after 1 shot with 16J gun brake holder between the barrel and front part with computer and display via back kick of the gun (tested with e.g. Hatsan 55S)
Conclussion: Combro 625 is possible to use only for CO2 or PCP guns withot back kick. Is it possible to use it at home in the room not outside (outside only with black tape which cover diods from the sun light)
