In Cheshire v. State, 568 So. 2d 908, 913 (Fla. 1990), the court stated: Cheshire alleges that the trial court improperly qualified a man named Allen Miller as an expert in blood-spatter evidence. It appears Miller's qualifications consisted of a single forty-hour course, three prior qualifications as an expert and his own field experience. While we agree that these qualifications are open to reasonable question, we nevertheless believe that the trial court did not abuse its discretion in allowing this expert testimony. Any deficiencies in an expert's qualifications, experience and testimony may be aired on cross-examination, provided there is some reasonable basis to qualify the expert. We believe such a basis existed on this record. Id.
