When your scanner can acquire a target at no more than 20m, your range is very limited and requires you to do multiple setups for longer distances. At longer distances, repeatedly setting up the scanner and targets becomes a very time consuming burden.
Acquiring targets at longer distances is key to saving time, yet your typical scanner goes no further than 20m.
The longer the distance, the more setups a typical scanner needs, possibly making a simple job an all day event.
Speed is key to optimizing productivity and helps avoid disturbing sensitive environments, which most typical scanners fail to deliver.
