Both valid solutions, but depending on the use of the pole we can recommend one or the other solution, of course the final choice will be up to you.
home use we recommend locking by hand (locking time only 4 seconds and lower cost of the pole).
For a Pole Course we recommend both solutions, an instant step because as soon as indicated to the students all will perform it; but also the passage by hand has advantages such as the negligible time for locking (4 seconds) but above all a considerable saving on the estimate for the purchase of many poles (money saved that can be used for good advertising).
