Just to elaborate a little from the above post, IMO the fixed mounted rangefinder shown below could be a more effective crossbow hunting tool than the Sig BDX in it's current configuration.
Say you're hunting on a field edge or in a location where you have multiple potential shots available to you at various ranges. Let's compare what's required with a Sig BDX vs. the LE-032 fixed mount rangefinder beside a XB30.
Let's say a good buck comes into view quickly but he's on edge and looking your way at what you guess might be 45 yards.
With the Sig BDX, you've got to slowly bring up the BDX rangefinder while you wait for the buck to look away. Of course, he might just decide to move on or you might actually get lucky and he looks away while still standing in place. Assuming you get the rangefinder up to your eye and back down without spooking him, you've ranged him and the correct LED lights up to give you an aiming point so now you can once again hope that you don't get busted as you bring the crossbow up to shooting position and place the lit LED on the buck's vitals.
With the LE-032/XB30 combination, you skip the first step above and slowly bring the crossbow up to shooting position hopefully as he's looking away. You push the corded button next to your trigger guard (or wherever you have it mounted) while looking thru the scope and placing the 20 yd. crosshair on the buck's vitals. Now you see the accurate distance to the buck in you left eye and move the correct reticle up to the deer.
Which method you prefer is personal choice but I'd take the second approach every time because it's less movement involved.
But what I would really want is to have a more compact Sig BDX rangefinder mounted on the crossbow that looks similar to the LE-032. It would even be better if it looked like the ATN rangefinder and had the display in the scope. Now I get to have my cake and eat it too so to speak.
Once, I have the scope up in my eye, I push a button and the rangefinder not only shows me the distance using my left eye (or my right eye in the case of the ATN version), but it also lights the correct LED and No Other
so I'm good to squeeze the trigger once I place that dot on the animal's vitals.
