Yeah, that’s a big no-no and I highly encourage everyone to get get a rover pole with a tripod attachment for their base stations and a bipod for their rover. Don’t get me wrong, level tripods and a tribrach plus a mounting adapter are great, but for less cost you get an unmistakable, on-point, fixed height level in 30 seconds every time. Of course like anything else they need to be calibrated once every 6-months or so. I like the Seco yellow aluminum snap-lock poles. You can hunt around though and find better pricing.
