    Comments about Gamma ERT 300 Tennis Computer:

    First, it's possible the one I used was defective, since it did not register dynamic tension as predicted by their conversion charts. Second, it was used to measure relatively low tension (45lbs) and gave readings in the mid 20's. It does not indicate tenths of a pound, that decreases accuracy e.g. a reading of 25 could be anywhere from 25.0 to 25.9.
    It was easy to use and looked well constructed.
    Was able to return it to Holabird with no trouble.
