    Sig 2400BDX Rangefinder $650

    Claimed range: Reflective-3400 yards, trees-1600 yards, deer-1300 yards


    I’ve wanted a rangefinder for a while and decided on this one primarily due to the claimed distances it was capable of measuring. My intent was to have a rangefinder that would work reliably at 2000 yards on steel targets.

    It came in the mail yesterday and I’ve been ranging everything I could in order to see just what it can do.

    Yesterday was terrible for testing. Dense fog through most of the day but I tested anyways. I could range trees out to about 350 yards but none in the dense haze of the fog. Not surprising later in the evening as weather cleared I was able to range to a house on a hill across the creek. I could also easily range any cars in the drive

    I was also able to range a brick silo at 1780 yards today.


    Trying out trees in clear weather I’m getting easy reads on trees at 1056 yards. It seems to read best against the trunk or heavy branches and I have a gap in good targets between 1k and 2k yards. It will not read the trees around the house pictured above. Hopefully I’ll find a spot to narrow down the limit. Also don’t what affect it will have when the trees bloom.


    It ranges pretty quickly and updates often. I was able to hold steady enough to range a car off hand at 2k yards. Sometimes this would lead to hitting other objects in between while ranging. In that case it display the most distant range measured when the button is released. I can see where this might cause an issue in certain situations but so far it’s given me the distance I wanted. It also helps when a range flashes up as I cross the target but then disappears before I can read it.

    Ranging modes are:

    AMR: Angle Modified Range, most likely to be used by bow hunters I suspect. Gives an adjusted range based on incline or decline angle in order to compensate for its effect on drop.

    LOS: Line of site, this is the true range and what I’ve been using for the most part.

    ABU: Applied Ballistics Ultralight: If you download the Sig BDX app you can set up a bullet profile and enter environmental factors. These will sync to the rangefinder and after ranging a target it will give windage and elevation holds. I believe these are limited to 800 yards but haven’t tested it.

    ABE: Applied Ballistics External, If you connect to a Kestral 5700 (possibly others) the Kestral will take the range and inclination data and use its environmental data to calculate windage and elevation holds. It really just save you the time of punching the numbers in yourself after ranging a target.

    Lastly there are two modes for ranging that work alongside the previous modes. “Last” and “Best”

    Booklet says “best” is for ranging a clear target in the open and “Last” is for ranging a target that may be partially obscured by brush. I have been using the “Best” mode. Haven’t had much opportunity to really test “Last”.

    Rangefinder has a 7X magnification which has been nice. I’ve looked through some with 4X and it can be hard to find the target. Glass is plenty clear for me.

    Uses a CR2 battery and with all my playing it still shows as full.


    Now I will complain about a couple of things.

    The case it comes with has a belt loop instead of a clip. I’d really prefer a clip. Personal preference I guess. Minor complaint though.

    Second, it doesn’t have a threaded tripod mount built in. They will sell you one for $75 though. Seems pretty expensive for a small aluminum ring with a 1/4” nut built in. Although it seems like a tripod won’t be all that necessary since it does read pretty fast.


    I’ll update after I use it more. So far I’m pretty happy with it. Does exactly what I wanted it to do. May end up springing for a Kestrel before it’s over with.

    I was hoping to do some testing with a little more daylight and possible try to range some cows at a good distance but the meeting at the RC club ran long. Still, I took the back roads home and did a couple tests. Both done at 8:15 this evening.

    Light transmission was actually pretty good but I had trouble getting my phone lined up in the low light. Did multiple readings of each target with matching results.

    I looked at the ABS but budget constraints held me to the BDX.

    Stopped for breakfast in West today and got just over 2700 yards in a white shed and 1600 on a cow. The cow was difficult and I had to hunt around the herd till I got a hit on a lighter colored one. Seems the black cows weren’t as easy to pick up.

    Cows at 1000-1200 yards in another pasture were easy with instant returns.

    Also got several easy reads on houses from 2000-2600 yards.

    Did you mount on a tripod? How did you hold it?

    The ones from last night I was testing sitting in my ‘94 Chevy pickup resting on the window. Not the smoothest idling truck.

    This morning for the cows I was doing the same but from a ‘15 Ford diesel. Somewhat resting on the door but still a bit wobbly. I could mostly keep a cow in the ring at 1200 yards.

    Yeah, when I used to spotlight coons I would always turn the motor off. Makes a huge difference looking through a scope, and sounds like a rangefinder too.

    I've seen the thing that clips to the window, to mount your scope / rangefinder on. I need to get one of those too.

    Appreciate the update.

    Couple more trials today. Both sitting in the truck resting my elbow on the arm rest.

    Ranging trees. Solid results, not hard to hit.

    When I shot this range the white calf was separated from the 2 cows. They moved in as I was getting my phone lines up for the pic. Calf is partially obscured by red targeting ring.

    That's good performance for a $650 unit.
