Inoshandiswawo kufambisa magetsi kubva kumapango ekushandisa kuenda kuzvivakwa. Inopa kuchengetedzeka kwakanyanya uye kuvimbika, inomira nemamiriro ekunze akaomarara, ultraviolet mwaranzi, uye kushushikana kwemagetsi. Zviri nyore kuisa nekuchengetedza, nemitengo yakaderera yekushandisa, inowanzoshandiswa pakugovera magetsi munzvimbo dzemumaguta nekumaruwa.
