Curious if anyone has any experience using the full capabilities of Sig’s BDX system and, if so, thoughts on effectiveness and value (capability vs cost).
After watching some videos* and reading a little bit, it appears that the Sig Kilo BDX rangefinders and binoculars communicate with the Sig Sierra3 and Sierra6 BDX scopes via bluetooth to provide show an LED pinpoint on the vertical reticle for where to hold for drop as well as an indication for windage (I assume you have to input wind info in advance). The scope also has LEDs at each end of the horizontal reticle to let you know if you’re holding the scope level (as opposed to moving the eye from the reticle to an external level). The system seems to account for elevation/environmental conditions to adjust for bullet trajectory (not sure if all or just more expensive versions) and will alert you if your target is beyond some preset distance (i.e., for self-determined ethical max range).
This all seems wonderful - if it really works. So, again, curious if anyone out there has actually used an Sig BDX system to full capability and, if so, did it work to expectation, was it overly cumbersome to employ, etc?
I bought both, but my scope is the next one up from the one you mentioned. I have only tried the binoculars and have not installed the scope yet. I picked up both on sale at two different websites (they are related to each other Scopelist and Eurooptics.) The binoculars are absolutely awesome. The clarity of the glass and large field of view. Not to mention it’s rangefinder is great. I do highly recommend. Also as far as calculating the distance without doing manual math number crunching, you might want to look into Huskemaw scopes.
I don’t have one yet, but it is on the top of my list of scopes to buy. Good luck.
My brother owns an Sig Sierra 3 BDX scope and range finder combo. I mounted the scope for him about a month ago and I was really unimpressed by its clarity. I like the idea, but I didn’t like the scope.
I’ve never shot it, I don’t think he has either, but we played around with it. It worked great in the backyard. It’s a pretty cool idea but I’d like to see it in better glass.
Turns out, this scope is illegal to hunt with in a lot of states. I just called my local field office in Utah and they confirmed the BDX scope is illegal as of this year. “New this year: No electronics may be attached, except for illuminated reticles.”
Apparently it is legal in all 50 states as long as it doesn’t have “laser!”
If that is the case, then ATN’s entry in this field would be illegal in some states. They recently came out with a new binocular that does exact same thing as the Sig Sauer bins. (I ordered it b/c I have an ATN scope with laser rangefinder, but i never received it b/c it was stolen from FedEx ground before being delivered) However, the ATN scope comes with a laser rangefinder.
Respectfully, your source is inaccurate, at least for Utah. That search result pulled up an article from 2021, when it was probably legal in all 50 states. Not this year. I noticed it on page 46 of the Utah Big Game Field Regulations where it states “New this year: No electronics may be attached except for illuminated reticles…”
I called the DWR directly and asked them. They were very quick to say the BDX is unlawful.
Also, the Utah code under R657-5-8 states: "(1) A rifle used to hunt big game must: (a) fire centerfire cartridges and expanding bullets; and (b) have no attachment capable of electronic function, other than illuminated reticles. (R657-5: Taking big game)
I checked with my gundealer, and she said they are also illegal in CA as well.
But why? Is it b/c they think it is another added advantage for the hunters?
I mean, hunters already have an advantage using firearms to begin with. You can shoot your prey without even being seen!
I have several of these scopes / range finder combos. They work well, the only thing is when you jump an elk or a deer, you need to remember to have everything turned on and synced. I have to send a email every year to CPW, here in Colorado to make sure that are still legal to use. As of right now , as long as the ballistic calculation takes place in the range finder and not the scope, it is legal to use in Colorado. Unfortunately, I believe that we will eventually follow Utah’s example and outlaw them.
My wife took her cow elk last year at 629 yards with the system. One shot and dropped it right there. I don’t think she would have been as confident to take that long of a shot with out using the BDX system.
The glass is ok on the scopes. You probably could get better glass for the money.
But why? Is it b/c it gives the hunter another advantage?
I suppose it was a good thing my ATN binoculars were stolen, otherwise I wouldn’t have been able to use it in conjunction with my ATN scope.
Wow. Seems like something that helps assure a clean kill would be welcomed.
