Field notes

The Carbon Express Maxima Sable RZ is a dual-spine hunting shaft with a.244-inch inside diameter and the Red Zone construction that stiffens the ends and leaves the flex in the centre, so it takes a CX Launchpad.244 nock.

It is offered in three spines, 350 at 8.4, 400 at 7.5 and 500 at 6.5 grains per inch, each with its own outside diameter, sorted to +/-.002-inch straightness and +/-1-grain weight.

It uses a spine-specific CX insert and takes a 19/64 field point rather than the micro-shaft 8-32, so match the point and insert to the shaft.
