What do you think - A Bluetooth Trackable Nock?

greghopper, I do recall people ASKING about the legality of using walkie-talkies and other radios. IIRC, the answer right from the start was that they were legal to use WHILE hunting, but not as a tool in actually locating game or moving game to drive it to other hunters. OK for contacting fellow hunters to change locations, come in for lunch, join in a blood trailing or retrieval, etc., and certainly to call for help if needed in dealing with accident or injury.

Re the other electronic devices, I recall when the bow-mounted rangefinders came out and were banned here in IN. It was OK to carry a hand-held unit and use it to range the deer if you had the time, and certainly to range the surrounding landmarks before a shot opportunity arose, as long as they weren't actually attached to the bow. Not sure if that has ever changed. The handheld ones always seemed to me a better idea anyway.

There was some controversy in some states when lighted pins came along, because the most popular types used an LED instead of an incandescent bulb, making them technically illegal as the LED is an electronic device rather san simply an electric bulb. I think most of the states where that was an issue later exempted the LED's from being banned. I do recall hunting one year in ND using a Trophy Ridge sight with a chemical light tube (bobber light) in a hole in the sight housing.....it sorta worked, but the light was so dim that it was ineffective until almost full dark, so I never used it in the field. The ND law had specified no "electric devices" attached to the bow, which made even the lowly incandescent bulbs illegal, but not the chemical light-stick "bobber lights"

Most governing agencies seem pretty eager to regulate, and tend to do so whether there is any chance at effective enforcement or not, which leaves us often with the result being another rule that only affects the law-abiding, and allows those who ignore the regulations free run to do so with little or no risk. Good intentions do not necessarily make good laws, but they keep trying.

I think in the case of the heat-seekers, I would have probably bought one and had it in the truck in case it was needed after a failed blood-trailing attempt, except that a friend's brother had bought one just before they were banned and we got the chance to give it a good tryout. It located every warm rock in his back yard, and the warmer side of all the trees, and would locate his large lazy dog if we got real close. We decided the conditions required for it be truly effective would be rare in the daytime and brief after dark, and that it wasn't worth the money. I suspect that assessment might be different now with some of the newer infrared devices, and I see there's even an app now for smartphones that will further complicate detection of their use, so there will likely be many more in use soon, legal or not.

I was tempted to take one of the earlier devices with me, unarmed, into standing corn, to see if I could effectively use it to locate deer. Never found the time to waste half a day satisfying my curiosity, though. Always kinda figured the final approach and shot would require plenty of stealth and skill to qualify as a legitimate hunting technique in my eyes.
