(Discussion of the transfer of the telescope in the backpack from the Astroforum)
xxx: for example telescope 1 - 18 kg VS telescope 2 - 20 kg Both without a machine can take only yyy.
Damn, guys, how are you, curious, pulling the baby on your hands? Or do you also pick them "appropriate-transferable"?
The ergonomics are better :)
WOW: This is an illusion – unlike a telescope, the grandmother hangs entirely on the shoulder belt, often straining the neck. This is a breakout of the back... The backpack hangs a significant part of the weight on the thighs, through the belt, there is a little left on the back, and the breakout is much less - no grandmother will cling to the man as a good machine backpack will do!
