... ab Hasdrubale Carthaginienses, et speculatores omnia uisendi et Scipio...

In English word order as much as possible: speculatores (habuerunt) tempus visendi omnia et Scipio habuit (tempus) ad comparanda ea quae (erant) in rem; "habuit" agrees with Scipio, the nearer subject, "visendi" depends on "tempus."
