HANDLE COMPATIBILITY
Per Penn: Slammer III and Spinfisher SSVi 6th gen series complete handles are interchangeable!
15-SLA3500 = 15-SSVi3500, 15-SSVi2500LL (NOTE: DOES NOT FIT SSVi2500)
15-SLA5500 = 15-SSVi5500
15-SLA7500 = 15-SSVi7500
15-SLA9500 = 15-SSVi9500
This only applies to the reel models listed.
COMPATIBILITY: If your reel model is not listed, it is likely NOT compatible.
Spinfisher V is not compatible, only VI of the SS reels, and some of them are NOT compatible in the SSVi, we will make note of them as we find them
