A quality needle or Probe also pays for itself in ease of insertion.
A quality probe, such as the IBP, helps in fast insertions and reduces coagulation pattern. But it also requires greater precision in placing the tip of the probe in the right place to achieve our purpose. The smaller the tip exposed, the greater should be the precision of your insertions.
The day that someone is able to invent a probe that can be inserted by itself, I'll be the first to applaud!
