    if you paid 500 plus for those mastercools, its no wonder you call'em junk. you paid entirely too much money for them lol

    they usually go for 320-350 @ at local supply house.

    but i wouldn't buy them even at 245, i have seen them for that little

    Just For Fun . . .

    I may be repeating your Mastercool digital manifold experience.

    As in a previous messsage in this thread I did the RMA thing and they sent me a new manifold after a month and after an address mix up at their end.

    When I tuned on the replacement manifold there were problems. Here is the word I got from Mastercool tech . . .

    "Alex
    Send it back it has a bad key pad along with bad connection wire."

    So here we go again. I'm asking them to test the manifold they send me the second time so I don't continue to be their testing department.

The next time I was on a emergeceny call late at night and the high side sensor failed and does not read any pressure. If I cannot hang them in the back of the van with my Digicools and I must "baby" them. then it is a piece of junk!!!! If I pay $500 plus for a set of gauges then I expect for them to be able to take abuse. This is a piece of equipment that is 99.9% of the time used outdoors. I am not into having a gadget that the only reason I bought it was to show off to my heating and air friends. I make a living with my mind and tools and if that tool does not live up to standards then it is a PIECE OF JUNK!!! Digicools have been hanging in the van for the last year and a half. Digicools are made to military specs. I have seen pics of digicools dropped 2 stories and run over by a truck and still worked. Mastercool service may reply quickly but I kept hearing that "oh sorry but we will ship them today" for three weeks after the unit had been there for 6 weeks. There is a reason Mastercool provides you a case for them, they expect you to use them under ideal conditions and once in a while, not hang on the rack like your other gauges. It will be the last time I buy a Mastercool anything!!!

    I do keep my Mastercools in the carrying case that was provided but that is true of all my tools that have cases it's just easier for me to stay organized that way. I use mine everyday and it sounds like I'm the only one out there that has any success with them and likes them. I paid about $300 and so far that has been money well spent.....good luck to the rest of you. I have checked them against my YJ analogs and they both get the same readings. Same with the micron coupling checked it against the CPS 200 I have and the readings do agree......I'm just a lucky guy I guess.

    I purchased a set of the Mastercools this spring and used them through the seasonn and did not expeince any problems. although I coved them when using them in the rain. They seem to have been a good purchase and accuracy is good. I have them hanging along with the analogs in the van with out problems. I want to move up to Digi-cools. But these have worked on a budget. From what OP have written I must be lucky with them.

    Mastercool Tester/User here as well... I just sent out for my sixth one because the previous 5 all had various issues. Vacuum readings, High Side not reading, Low Side not reading. This last one was good for a while, and now it will not even turn on. So, I'm getting my last one and will continue to trade them in until the warranty is up, and then wait for the new Yellow Jacket I heard about in September to come out. If I were me again, I would stay clear from this product. It is cheap though.

    Go here for a well thought of digital gauge set. The 1250 is what I'll be purchasing for our 2009 A/C season. http://digi-cool.com/

    You might also do a search here on HVAC-Talk as there are several threads on the subject of digital manifolds including the DigiCool.

    Hi . . . KLEINman . . .

    I just bought a pair of KLEIN offset snips and I really like them . . . good stuff.

    Are you an expert refrigerant leak finder? I'm looking for all the help and tips I can get as I have trouble finding leaks. It seems to be very time consuming.

    What is/are your favorite leak detectors?

    What techniques to you use to find leaks, even small ones, fast?

    Nice purchase, i will be getiing some soon too. As for checking leaks i am in no way an expert, but i would recommend either this leak detector, ive used this in work with really good results.http://www.keenzo.com/showproduct.as...1449775&ref=GB

    Or i just use the old standby, soap bubbles lol.

    IMO i will never use dye, i believe that it is not good at all for the compressor or the system, a guy that used to work for us loved the stuff, every sight glass was green that he worked on lol.
