    To those Guys who have Sman4's Testo's and Digi-Cools. If a Tech could only buy one set, which one would you recommend???

    DC's of course.

    I only own one brand (have an older one for a back-up)... I think you can guess which brand...

    Why DC's? It seems that the other digital gauges are pretty comparable. From what I read, Fieldpiece has good tech support, not sure about Testo and, I've read that Digi-Cool can be hard to get a hold of. I'm also interested in specifications. Can one particular gauge do something that another one can't? Do you find a certain capability of one gauge important? To be honest, I'm leaning toward Digi-Cool's but, I want to make an educated purchase.

    Honestly, I have only owned DC's. The previous one, a 1200 that was upgraded to 1250, served me for over 6 years. It has been dropped off the roof onto concrete (I defy ANY other unit to stand up to that), left in the rain, drowned, sunburned, frozen, literally run over by the van tire, and probably other things I do not remember.

    I doubt any other unit will stand up to half that.

    Doug and Brenda Lockhart (on the forum here) run DC, it is a family business. The ONLY folks who have customer service issues with them, as far as I can tell from reading posts, are whiners.

    The SMAN 4 has the most capabilities. It can receive wireless input form other fieldpiece tools to help determine target superheat. It also has a built in vacuum gauge ( would not use a vacuum gauge on a manifold myself )

    The Testo 570 has data logging and can also has a vacuum gauge built in. ( never used one myself )

    The didgi-cool can be mounted on any set of gauges ( with swivel adapters ) and has an analog bar graph that can help troubleshoot TXV and leaks ( like a vibrating needle on analog gauges ). Digi cool is most known for durability.

    Digi-Cool, you won't be disappointed. The Sman4 is tempting bc of the wireless feature, but IMO its still not solid technology. Its in its infancy. Fieldpiece has excellent customer service. Digicool has excellent customer service as well.

    I have the 570's and the Sman4, I use the Sman's almost all of the time. If I had bought them before I got the Testo's I probably would not have bought the Testo. Just my preference. BTW the way FP brags about the way it is easy to change the refrigerant settings is a PAIN. I think they should be numerical.
    I just use too many different refrigerants.

    say what! ?
    the testo 570 can print, read
    subcooling and superheat and ODT, you bet evacuation, weighin refrigerant, measure amp draw,read vacuum,perform tightness test on timer, and print all this out on one ticket size:form.

    the only thing Sman4does the 570 does not is calculate target superheat.

    the SMAN4 is good for what it can do, what if you want a fully functioning gage manifold, then the 570 is a better choice. I have said this several times and at the risk of sounding redundant, I will repeat: I own two AK900s, SMAN 4 and SMAN3.

    I also own Testo 557 and 579 and no but keep the ladies of each they are all fine pieces of equipment. in this case it is too which is on, however to say that s m A n 4 has more capabilities then Testo 570 is just plain wrong.

    I thought the Sman4 could also print through fieldpieces PC software ( maybe I'm thinking of the HG3).
    The AMP draw is a feature I forgot about though. I had no idea it could weight in refrigerant.

    Uncle also thought the testo could weigh in refrigerant. Are you sure it can do this or are you just able to fill in the blanks on on the printer ticket?

    Crap. I mean you have to enter the numbers and they will print.
    The only Testo that weighs refer is the 560.
    It hookes up to a testo scale with data cable.

    But what I like about the 570 is the 552 slaves to the 570 and shos the miron level on the 570 screen! !!!!!!

    I thought the Testo could also cook breakfast.
