Vision 175 produced by Horton - Archery History

1 Teater All rights reservedCrossbow Report: Vision 175byHortonby Jon Teater of Archery EvolutionArchery Evolutionreceived the new Vision 175 produced by Horton . The Vision went through a standardandregimented performance test. The focus of these types of tests is to determine, for a specified product, the performance , the goal is to provide those archers that enjoy shooting and/or hunting with appropriate objective information, as well as some subjective commentary, for aiding in the purchase process. With that said, this evaluation is by no means conclusive; some tests could not be performed due to limitation in resources, time, or budget.

2 Each archer should assess what is important to him or her and interpret the resultswithinthe context of thisarticle. As always, we recommend that anyone who is considering a crossbow, shoot as many different makes/models as possible to determine what best suits their individual needs and desires. Due to thelack of testing methods/procedures available publicallyfor crossbows, Archery Evolution has developed testing guidelines to help better understand the products that we will be evaluating. These methodsarepublished and available online. Production Information and Testing:Introduction: Horton , one of the oldest crossbow manufacturers, is keen on providingproducts that boast innovation.

3 The Vision 175is developed on a similar platform as itsbig brother, the reCon 175, but without some of the tactical features. The crossbowhas some unique technologiesand featuresthat will draw interest from a visualandshooting perspective. The Vision 175wasprovided to Archery Evolution as a package, which includesa multitude of components thatwereexamined thoroughly forany imperfections. The crossbow was received with the following items:cocking aid, Mult-A Range 4X32 Scope with lighted reticle and rings (allen-key style hex wrench included), scope cleaning cloth, quiver (the quiver mounting bracket was pre-installed), quantity three(3) Lighting Strike MX Arrows (fletched, nocks and inserts installed and field point included), manual and service string.

4 Additionally, the stirrup, which isnot installed, but provided in the package,requiresone bolt for installation;anallen-key style hexwrench is providedto torque down the mentioned hardware.

5 The review focusedon string/cables, eccentrics,limb and limb pockets, rail, prod, stock, butt plate, trigger housing, trigger and trigger guard. The review revealed minor tooling markson the eccentric, specifically in the inlet that houses the string post and in the inlaid cutouts ofthe cams. Additionally, the cams did not have any noticeable sharp edges or burrs. A small void in film dipping was noted on the butt plate. Overall, this product was up to par as compared with competitors, and the mentioned imperfections were determined to have no affecton performance.

6 Thereafter, the product goes through a 100-150 shot cycling to verify functionality. Some minor testing was done, butthe focus is to detect any issues or concerns with the productbefore starting theactual performance testing. Theprimary issue noted was string serving separation. The high load andacute string angle created by the Frontal String Technology at full-draw is the distinguished cause of the separation. No other items were discovered during this portion of evaluation. The crossbow is next evaluated on the five (5) criteria outlined below:Detailed Test ResultsDynamic Efficiency:The dynamic efficiencyportion of the testutilizes a Revere Load-Cell controlled by a winch device; the load-cell connects tothe crossbow with a cocking aid.
