OK I’ve got both the tripods set up at the lowest height to ensure that the stability is at max for both of them. I’ll use the BTX for this first part of test as they’re angled and I can get close to the ground compared to a straight 15X Bino.
The ground is flat enough here that I am not leveling by extending or shortening legs, I’m just moving the tripod around until it’s flat enough to glass. That’s as close as I’ll be able to get it to an objective head-to-head.
Looking at cattle at estimated 1 mile
The SLIK is at 17” to top of the Pan Head. In winds gusting to 10mph, no noticeable shake
The Outdoorsmans is 19” to top of Pan Head. Same winds, no shake (as I’d expect from a 14 oz heavier tripod)
Now I’ll go to max heights.
SLIK goes to approx 50” (w/ center column extended) to top of Pan Head. This is max for that tripod.
Glassing those cattle for a few minutes and allowing the wind gusts to hit max, which I’m estimating are above 10mph now, there is noticeable shake but I can still see the animals just fine. More of a nuisance than affecting performance.
The Outdoorsman went to 59” for comfortable standing glassing, but there were still about 6 inches left in the column that I could’ve extended it.
So even with nine more inches up in the air, it was still more stable than the SLIK, but only by a margin. It wasn’t as big of a difference as I thought it would be. Now these are not high winds and I would expect that difference to be greater the higher the wind got.
Next I repeated the same test with the 15X, but they are just not big enough to pick up a lot of wind, nor is the magnification high enough to notice a big difference. (BTX ARE 35X). Pretty much the same results I got a few weeks ago—the BTX is worse due to all that surface area, you’d think the weight would offset it but it doesn’t.
I finished up with some video through the PhoneSkope
to compare vibrations.
I’ll review it at home and see if there’s enough difference in the estimated 10-15 mph winds to warrant making a video.
