If you want the most safty oriented crossbow on the market get your Dad a Tenpoint ,, if you want to get him the simplest on the market get him an Excaliber one thing you should do is buy from a manufacture that makes only crossbows,, Tenpoint and Excaliber are the best on the market you pay more for them but when it comes to crossbows you get what you pay for... and no matter which you get have a Tenpoint Accudraw or Accudraw 50 put on it the best cocking aid on the market. dont think any will argue that..
