Onuris, Check the Indiana Criminal Code agian. I copied and pasted it below. You may not use a spotlight in or out of a vehicle. I have had some concerns here with the new high powered LED's and I think some people may find themselvs in hot water over game laws like this. (The second sentence here is the killer) I would not walk out of the woods after Deer hunting with a 300+ lumen light here in Indaiana if I had a gun with me. There was not much of an issue when hunters had a Minimag with them but something like a TK35 on turbo?
Spotlighting: It is illegal to shine a spotlight, searchlight or other artificial light for the purpose of taking, attempting to take or assisting another person to take a deer, or to shine such a light while in possession of a firearm, bow or crossbow.
It also is illegal for a person to deliberately cast a spotlight or other artificial light from a motor vehicle if in possession of a loaded firearm, bow and arrow or crossbow.
I had a lengthy conversation with my DNR friends again about this just this past weekend. I live on 147 acres of mostly wooded land. If on my own property, outside of my vehicle, guns unloaded, cased and/or locked inside my vehicle, except my carry handgun, they would not cite me. If in my vehicle spotlighting, no firearms other than carry handgun, they would not cite me. Now if I was on my quad with a loaded rifle, and a spotlight, would be in trouble. Is perfectly legal to spotlight and shoot coyotes any time I want to on my own property. Just not from a vehicle. We do it quite often off shooting bench, bait them in with rabbits and electronic calls. Sometimes on foot as well. In fact were shooting them with one of my DNR friends and another who is a county Sheriff's deputy a few weekends ago. Favorite rig is my Don Geraci custom .22-250- Nesika action, Jewell trigger, Kreiger barrel, McMillan Tooley MBR stock, US Optics SN-3 3.2-17X scope. Have an Olight SR90 mounted on a tabletop tripod to spot them with, as is way too bulky to mount on gun.
Basically, it boils down to intent of the law, situation, opportunity, and zoning. For example, using the Indiana Code that you posted-
It also is illegal for a person to deliberately cast a spotlight or other artificial light from a motor vehicle if in possession of a loaded firearm, bow and arrow or crossbow.
I have an Indiana lifetime carry permit. If I was in town, carrying my .45, and was shining my light on street signs to find my way somewhere, am I breaking the law? No, because it only applies to land that is zoned for hunting, eg. state land, agriculture, etc. And no reasonable person would believe that my intent was to spotlight deer in the middle of town.
Back on topic of OP. Perhaps consider a ThruNight Catapult. May be able to find one used in your price range.
