APEX PRO The highest performance pro race mast. This is our lightest SDM mast with the fastest reflex response for ultimate performance. The Apex taper has smaller diameter mid-sections with increased wall thickness for increased reliability. Alternating texture patterns in the boom area increases friction for less slippage. This eliminates the need to overtighten the boom, decreasing stresses on the mast. / ULTIMATE PERFORMANCE / INTEGRATED FERRULE / 7 MEASURED OFFSET ACCURACY / SLIPLOK PREVENTS BOOM FROM SLIDING MODEL SIZE DIAMETER IMCS WEIGHT APEX PRO 400 APEX SDM 19 1.42 APEX PRO 430 APEX SDM 21 1.55 APEX PRO 460 APEX SDM 25 1.66 APEX PRO 490 APEX SDM 29 1.9
