Just the facts.... From the Idaho IDFG FAQ. Their answer is a quote from the Big Game reg pamphlet. Page 100 in the 2020 2nd edition. )Not had your coffee yet? A bit tissy to start the day... relax.
Last I recall any electronic devise attached to a firearm or archery for hunting big game purpose is not legal in MT. If not the case. Good to hear. Now, ill certainly look it up as you've not quoted regs that state otherwise. Thanks for the heads up it may be legal in MT.
(There is an old answer out there from 2006 that says it is illegal. The header on the FAQ page warns patrons to search for the newest info. )
Why is it legal to have a tritium powered scope on a rifle but not on an archery sight on a bow?
Illegal to use..
Rifle & Shotgun... "With any electronic device attached to, or incorporated
on, the firearm or scope; except scopes containing battery
powered or tritium lighted reticles are allowed."
Archery... "With any electronic or tritium-powered device attached
to an arrow, bolt or bow. Except disabled archery permit
holders may use a non magnifying sight with battery
powered or tritium lighted reticles.
The Idaho Fish and Game Commission support equipment regulations for archery and muzzleloader equipment that are consistent with the primitive nature of the weapons.
