The Howard Hunter is really a Damon Howatt Hunter with Jack's logo on it. Now there is nothing slouch about a Damon Howatt Hunter, they are awsom bows in their own right. However, they do not have Jack;s limb design, and the glass and core ,aminations are not spine matched.
Jack's customers had been bugging him about coming out with a 62" model. He did not want to retool sna rejig for 62" so he bought about 50 Damon Howatts unfinished and did them with his logo. VOILA!! The JACK HOWARD HUNTER. He told me that he regretted doing it because it was not his design. However, I think he got the idea for the JET riser from that experience. Compare the riser design of thr Howatt to the JET. Notice any similarity?
As far as the TargetMaster Supreme, if Jack had not sent me pictures, and told me all about them, I woul say they do not really exist. Been looking for onw for years, never found a trace, or anyone else that has. Still looking.
