There is no piecing one together....All you need is the unit and a tripod. Only item you could consider is a battery pack as they suck batteries. I use the Bolt jump box I keep in all my rigs. I see folks buying aiming devices and such but I don’t get it as I just aim it within a couple feet of the target with it about 4-8” to the side of the muzzle and the muzzle about 1-3” in front of the unit and it works without a hitch.
What did you think you needed? Just wondering..,
