To slingbow fish with the Hammer XT handle what you need is a Archery Accessory Adapter $10.00 and a Rail Adapter $12.00 to hold it. (Those are both clickable links that will take you to that page.)
You can use either the LT Slingbow Head or the XT Slingbow Head.
The next part we DO NOT carry but I'll include a link to where to get those as well! What you need is a reel, reel seat, and a power rod. We recommend RPM Bowfishing. Here is a link to their complete kit listed in their online store. The reel seat will screw right into the Archery Accessory Adapter that we sell.
