I thing is for sure, better keep it out of the rain. LOL I remember when cams came out on bows, I bought the first one that had four cams. Everybody laughed. Look at them now and I have the latest Mathews. I think air guns are the same. Mechanically I don't think you can improve much more, however electronically can improve a great deal more. Springers will improve more too but no big leaps in technology. That's my 50 cents. P
