Ingcaciso yeMveliso

Iincakuba zePDC ezinde zisebenza njenge-close-bit stabilizer kunye ne-reamer egcina umngxuma kwi-trail ethe tye kwaye ijikeleza kakuhle eludongeni ngokutyibilikayo.
IMpuma Ekude iphinda ivelise i-PDC yokuvula umngxuma kwi-HDD / Akukho-Dig isicelo, nceda uqhagamshelane nathi ukuze ufumane ulwazi oluthe kratya.
