The old Unispotter slide hammer is no longer being sold but we have a couple of service kits if anyone needs them. These kits are normally sell for $9 but we have a couple that we can sell for $5 each. This is for the slide hammer that was sold with the 4500 starter kit. The parts and link are shown below but if you call and ask for it we will give you the discount price. Only two available so even if you don't need it now it can pay to plan ahead.
