An automatic sensor inserter is disclosed for placing a transcutaneous sensor into the skin of a living body. According to aspects of the invention, characteristics of the insertion such as sensor insertion speed may be varied by a user. In some embodiments, insertion speed may be varied by changing an amount of drive spring compression. The amount of spring compression may be selected from a continuous range of settings and/or it may be selected from a finite number of discrete settings. Methods associated with the use of the automatic inserter are also covered.
