This.I had send it on two of my rifles, but I sold them and went back to bubble levels. It is a neat gizmo, but it sticks out too far from the rail and if you forget to turn it off, it can burn through batteries pretty quickly unless the gun is perfectly stationary in a safe.
The final determining factor for me was to plug-in small degrees of cant into a ballistics calculator for shots at various ranges. When I discovered that bubble levels are accurate to well under 0.5°, and that that amount of cant doesn’t make very big of difference within 2000 yards, I decided that the electronic levels were not worth the hassle, space, and expense.
0.5 degrees of cant- the minimum amount TRASOL allows you to input - changes the windage by < 0.2 MRAD at 2000 yards with a 338LM. IIRC, when I checked my bubbles against a digital level, their resolution was on the order of 0.1 or 0.2 degrees, which has a negligible effect on wind dial

LmHello, just wandering what level are you guys using.
Hello, just wandering what level are you guys using.
The turret caps are not a reliable measure of the crosshairs. If you check the crosshairs on a distant Plumb line, you square the scope, and then level the Spuhr out to correspond to the vertical crosshairs, as checked by a plumb line. After all, you had to zero that send it level. So you’ve just compensated in the way you set it up and the reference that you’re using, the top of the scope cap, could be off. If I were truly interested in perfect level, I would never do that. I would use a plumb line and make the levels correspond to the crosshairs as the ultimate reference with the plumb lineDid someone say vertical? Sendit vertical is the way to go! Notice the Spuhr bubble is off? Verified w 2 Sendits and a bubble level on top of scope turret. View attachment 8025619
thats what i did with my method, doesn’t matter if gun isn’t 100% level, all that matters is crosshairs tracks with direction of gravityIf I had the set up that you have pictured above, I would have first leveled the spur bubble and locked the bipod. I would have then rotated the scope in the mount until it was level on a plumb line, so that the Spuhr bubble corresponded to perfectly vertical crosshairs based on the plumb-line reference, and I would have ignored the top of the scope cap. Then I would’ve locked it down and checked it. Then I would’ve put on the send it, and re-leveled the send-it to correspond to the spur bubble AND the crosshairs on a plumb line. I think that you are building in errors based on assumptions. I would not do it that way if I were concerned with perfect level.
my inner ear must be off then, sometimes it works, then sometimes depending on terrain (research gravity hills) is way off. a bubble level is so cheap and easy to set up i wouldn’t ever be caught without oneDid you ever try hanging the Sendit vertically?
That’s how I mount mine as I agree that horizontally it sticks out a good ways.
And I agree that the level in my inner ear works pretty dang well.
I use 2 Sendit levels and a torpedo level on the rifle in a vise before I even mount scopes. I then mount my scope, cking the crosshairs against a plumb line w the use of level then verifying it w a tracking test. 2 out 3 Spuhr bubble have been slightly off. I mainly run EraTac adjustable mounts now on my LR rifles and use the same mounting process.The turret caps are not a reliable measure of the crosshairs.

I have the perverse impulse to rebuild the arduino compass/level I made and add audio output to it. Make it do Morty's "oooh's" and "ahhh's" close to level then "Lambs to the cosmic slaughter" and "Reality is poison" for Left and Right tilt.Once I bought a level, I realized how unlevel the world was.![]()
This is the way.shine light through scope backwards, turn your diopter way out, lowest magnification, match crosshairs shadow to plumb line, make sure bubble is center, done.
100% perfect every time

How does the average Joe obtain similar results when mounting a new scope?Quite a while back, I had a couple of rifles put together by Charley Robertson. Here's his take on mounting a scope: https://scorehi.com/precision-scope-mounting/
I’ve had very good luck with a wedge style optic leveller. Cheap, fast, and super effective.How does the average Joe obtain similar results when mounting a new scope?

There can definitely be that aspect of optical illusion.I looked and looked on the internet, and I can’t find any study or information on how well the human brain can visually determine level, but I KNOW it’s not two degrees. This is stupid. If you hang a picture that isn’t level anyone can easily see if it’s off by two degrees. If your balance was off by two degrees it would seriously effect your ability to participate in sports. Part of determining visual level is your brain comparing your sight picture with your body’s natural balance. There was a YouTube with a European comparing his eye’s level to a digital one, and he was less than half a degree off every time. This tracks with my experience. For me it’s a training aid, and the only reason I would stop to check it would be shooting off a slope to another slope where it could create a optical illusion.
