The “Hunter Express SL” is the top model of the Firm Horton. She is designed to reach a speed of 300 fps (91 m/s) with lighter arrows. However, this compound crossbow is still using a very conventional chordsystem, a dacron string and a plastics-mantled steel cable. Because of the lighter arrows, the spare energy is directly carried into the chordsystem and the bow. Nevetheless, the “Hunter Express SL” is as a tradition of all Horton crossbows very handy and user-friendly (e.g. height adjustable Diopterrail). Shot with normal 31g or 32g arrows, you will hardly experience problems with the long-life cycle.
