The Proaim Skater Dolly is only good as long as you drive straight. If you're trying to do curves with it, it becomes pretty much unprecise. I have tested it and I can not recommend it.
The best one I have seen on IBC 2011 was one from Konova (there were more manufactures, but Konova performed best). I don't know if it was just a very good sample, but it was able to drive in circles around a center spot without drifting to the side.
BTW: The accessory arm solution for mounting the camera is good. If you need more stability, you should buy a small weight for a dumbbell and simply add it to the centre where the accessory arm is located (make sure it's not too big, else it will block the wheels).
guys,there is many ways to get height, just need to think outside the box a little bit..how about a moveable portable flat surface with adjustable height ...you got options ..it wont be the most stable option *between large dolly,slider,or crane, but with careful movement it will be very close ..
Ditto on any flat surface, even vertical walls, round steel poles, street signs, car roof/hood etc, so quick and easy to get a steady motion effect and fits in the suitcase for travel.
@PixCanFly Yeah, I get that :) But what if you want a creep / side at eye level? I dunno, I've only got a standard dolly at the moment and in all honestly I can't see myself using a skater dolly that much, so I'm surprised to see sammy say he uses it the most. It makes me wonder if I'm missing some obvious here!
I find my self using a skater dolly the most out of the slider and jib that I own ..I like that its compact and nearly works on every flat surface ..The one you posted here looks great
