Can you use a See All Open Sight (http://seeallopensight.com/index.html) during a Muzzleloader Only or Archery Only season?

Answer:

Based on a review of the website, it does appear the sight is legal for muzzleloader and archery only hunts in Idaho. 

If the sight created a magnified view of the animal, or contained any electronic or tritium powered light source – there would be limitations on their use in Idaho.
