Thank you then for being the first person on this thread to bring relevant context to the discussion.I have tons of experience with thermals, weekly actually, for the last 13 years being a fireman, but I really appreciate you developing a ten page story based on one statement I made regarding some guys I ran into. The thermals we use aren’t built for long distance as they have no magnification, but I’m very familiar using thermals around homes and animals in all weather and light conditions. I whole heartedly disagree with your statement where there is little time when a thermal is beneficial. And antlers/ tails are connected to an animal, therefore they are warmer than a large portion of hunting season temps which means visible to a thermal. Maybe not the main beam tips but close to the head the body heat conducts up the antlers. I’d agree they aren’t visible in summer months or hot days, but that’s just not the case here in Idaho during most of hunting season.
And the thermal I looked through hunting was mid day, I was glassing a hillside with my Swarovski EL 12x50’s and found a bedded doe with the guys thermal I hadn’t seen with my cheap binos. I NEVER said you can see through an object like you wrongfully stated, but there’s gaps in brush you can still see a heat signature through yet it’s hard to make out an animal with binos under the same situation. Heck you can’t see heat through a clear glass window with a thermal, so I’d definitely not say you can see through objects, that’s ludicrous.

I respect that there is a lot to digest in the previous 3 pages, so I won't hold it against you that you probably missed some of my previous content on the subject. I had said almost exactly what you had pointed out... that thermals can't see through glass or water, let alone obstacles (a common misconception by those who have not used thermals extensively).
I won't dispute that some portion of an animal can be seen through a bush, but it is important to emphasize that any heat signature being collected by the thermal is reading something that is 100% in plain view... even if that something is only a tiny portion of a deer that is visible through a bush. The language that IDFG used in their survey was essentially that a thermal is a device that allows the user to see things that CAN'T be seen with the "naked eye". This is a misleading characterization of the capabilities of a thermal device... folks who haven't used a Thermal in context, generally perceive it is able to see things that are truly hidden (kind of like comic book level XRay vision).
I also agree that it is theoretically possible to see the heat from an antler... but practically speaking, those kind of details are impossible to see beyond just a couple hundred yards (at least with the thermal devices commercially available to hunters... perhaps some large military grade device would have more resolution... but cost and weight would limit its usefulness. )
I will also reiterate, that the primary benefit to the thermal (when conditions warrant its use) is that it cuts time off of glassing. You could have, and probably would have eventually seen the bedded doe in your example. The more experienced the hunter is with glassing... the quicker they are at finding game with their binos or spotter... and as such the less effective the thermal is. It might have taken you an extra 30 seconds to find that doe without the help of the thermal... maybe it would have take you an extra minute, or 5 minutes, etc. In my experience, 95% of animals or objects I first identify with the thermal would have been seen and found within a couple minutes using standard optics. As such, it is a useful tool... but one that is not as useful as the inexperienced would assume. Out of 30 plus game animals harvested with my rifles and gear over the past couple years... at most 3 or 4 were found with the thermal (and only one... my 2022 Wolf I harvested) was in a location and manner that it was not realistic that I would have ever seen it without the thermal... so in my opinion, making the use of thermals illegal in Idaho will have an insignificant impact on harvest rates.
I will also add that there are some weird anomalies that anyone who regularly uses thermals will likely have noted... for example, I have found a thermal more useful in finding deer, but for Elk and Bears... I almost categorically find them quicker with my binos in almost conditions... it may have to do with how easily elk and bears stand out in their natural environment... for bears, it also probably has to do with the fact that I see most bears in the afternoon when thermal conditions are the worst. Likewise, most archery hunters will find a thermal almost useless... I wouldn't bother taking mine if I were hunting the rut...
My whole point with this thread is not to dispute that tools like thermals don't offer some advantages... but I do want to educate those who haven't used them to help them understand their comparative usefulness. The perception amongst most proponents of banning thermals is that they are MORE useful than they actually are. To put it in perspective... here are the common tools that I carry in the field... all of the following are MORE important to me than a thermal...
Knife
Headlamp
In reach
Range finder
Binos
spotter
Suppressor
Rifle
Tripods
Phone skope adapter
Phone/maps
Walki talki
Load capable backpack
Spare ammo
Rear rest
To help put in context how I rank its importance...
I would however trade having the thermal for my sit pad, backup tripod, a 10x rifle scope vs an 18x rifle scope, a 1000 yard rangefinder instead of a 4k range finder, a standing height tripod vs a kneeling height tripod. A rifle bipod vs a rifle mounted tripod. Backup dyneema shelter. Big spotter vs a small spotter.
Again the point here is that the rules as written are not acceptable... but they could be if a robust study and analysis yields data that proves that limiting these particular tech tools is the best way to get the intended benefit... and if the rules are written correctly so they are not redundant or lack enforceability. But I think it is far more likely that a study will actually show that restrictions on thermals, NV, game cameras, etc will yield very little benefit compared to the benefits that could be seen limiting archery equipment, range finders, bottle necked cartridges, and putting more resources towards conservation.
