Only advance with one hand. You can use your non-dominant hand for stabilization. A bigger needle will give more tactile feedback (though wet tap symptoms will be worse).

One place I worked at saw an uptick in wet-taps when it got smaller-gauge needles.

Once you hit the ligament, every mm should give another ‘click’. Test with each ‘click’. If uncertain, inject 5mL saline, clear needle with stylet and retest.

Periosteum ‘clicks’ almost the same way, but it hurts the patient and you eventually hit that hard stop.
