Does ERT-300 have the power switch so it can be turned off?

    I heard Mini-STT doesn't have one, that's why it consumes battery quick. Wonder how this is handled in ERT-300.

    You put the ERT-300 on the racket then press the yellow button on the ERT-300 to turn it on then it will show you the Dynamic Tension then it goes into sleep mode.

    I have been using it for over 6 months and haven't had to replace the battery.

    Mini-STT claims its batteries can last for 2 years. I suspect both ERT-300 and Mini-STT don't have an explicit power button, ie, use the similar circuit design.

    I have both. Both automatically power down in a matter of seconds. Both have long battery life and easy battery replacement.

    I have the Mini-STT. It never powers off. It does not consume the battery, unless you use it daily.

    L4L, you are right the head size & tension display still appear, but the lbs kp & ms switch off automatically. Nonetheless, it appears to go dormant and the "start" switch needs to be pressed to reactivate and take another reading.

    Wonderful that I got replies from both camps! Thank you. Can you please share some opinions about the products, ERT-300 and Mini STT? Are they more or less the same or one is more superior than the other?

    I am debating what to get. So your input would be greatly appreciated!

    If you have an iPhone, iPad or 4th gen iTouch. Racquet Tune is a better alternative.

    I don't have an iPhone, yet. Is that because something you don't like about Mini-STT?

    For me I didn't like the Mini-STT because you had to make the vibration yourself (leaving more room for error IMO) instead of the ERT-300 which makes its own vibration (for me it's much more consistent than the Mini-STT IMO).

    The Mini-STT always was about 2-3 lbs off when I used it.

    The Mini-STT is definitely cheaper than the ERT-300 but I think the ERT-300 is a much better tool.

    Yes, I am concerned about that part that the user has to create the vibration. On the other hand, it may be more durable because it has fewer mechanical parts?

    That could be true,however I have not seen that happened to my ERT-300(which I bought used then used it for about the last 6 months and I have never found a problem).

    I spoke to a Mini-STT reseller, who suggested to use a spone to create the vibration. Do you think that would work? Yes, I am really concerned if I can make the vibration consistent enough.

    I think you mean spoon (spone) right?
    I don't see how a spoon will help make it more consistent.
    If you're going to get the Mini-STT it's recommendable to always to have the same exact item and hit in exactly the same spot in order to diminish any inconsistencies IMO.

    EDIT: And always make sure with either machine to place it on the same exact position on the racket (for me I try to do it on the center cross which for my 18/20 racket is #10).
    If not then you will start seeing changes in the reading.

    Yes spoon it is. I was so so excited to be able to get some expert insight! Likely I will go for the Mini-STT as it is cheaper. I will take measurement as soon as a racquet is strung so the baseline is establised. Then I will use it to learn how much the tension is off after games. After I know the tension depreciation behaviours of the strings / tension, I probably don't need it as often.

    Not really, I don't have an iPhone, but I do have an iPad. RT cost wise is a better alternative at a couple of dollars.

    Do you find RT and Mini-STT agree to each other most of the time? Thanks.

    They come out pretty close. Though you have to get a few readings on both to get a good reading.
