Questions and Answers for Cressi Spare / Replacement Gun Pump for Cressi SL / Star & SL Speargun:
Can this be used for a Scuba Pro Magnum 70 Spear gun ?
If not do you know where i can get one that does ?

No the Cressi pump will not work. Since Scubapro has not made this gun for 15 years, it might be time to buy a new one.
Even if you can get the Scubapro pump, the internal seals are going to need to be replaced and your search will start all over again for those parts.
