How to investigate an object in front of the player

I am trying to use transform.forward to detect the front object but there is a problem. Since transform.forward can only check the GameObject’s position on the Z axis (blue axis) of the transform, the object cannot be detected when it is higher or lower than the blue arrow. So, is there any ways to detect the front side of the player exactly? I hope you can help me, thanks!

 public void DetectThings() {
     RaycastHit hit;
 
     if (Physics.Raycast (playerTrans.position, playerTrans.forward, out hit, InvestigateDistance)) {
         if (hit.collider.tag == "Portable") {
             Transform PICKUpTrans = playerTrans.gameObject.GetComponent<PlayerController> ().PickUpPos;
             GameObject GOTit = Instantiate (hit.transform.gameObject, PICKUpTrans.position, PICKUpTrans.rotation);
             GOTit.transform.parent = playerTrans;
             Destroy (hit.transform.gameObject);
         }
     }
 }
