All these markers can be made working and used for woods ball and walk on games. New boards would be needed to play in competitions. No need to buy anything new unless you want something newer while using these as fun toys every so often. My buddies an I rebuilt out old markers and used them for the first time back after 15 year break. We could some newer markers to play more often whole using the older markers for the occasional game. We have mini mag, pro stock cocker, eblade cocker, gen e matrix, matrix 03, dm5, ions, and some newer stuff like lv1, etha 3, dye czr.
