    This meter is very accurate and works great. I found the included thermocouples cumbersome to work with so I went out and bought the clamp on style. I turned the included thermocouples into wet bulb thermocouples with an old hollow shoe string and alligator clips.

    Pros:
    - Fast accurate readings of two probes
    - Solid construction
    - Good battery life

    Cons:
    - Have to press a button to switch between the two probes, would be nice if both could be seen on screen at the same time
    - It's a tad bulky
    - The thermocouples it came with were poor quality and both broke quickly
    - The carrying case it came with is pretty bad and I ended up just tossing it

    I really like this Fieldpiece dual thermometer. Build is very sturdy. Accurate out of the box. Large LCD screen so I can see clearly in lighted conditions but the only downfall of the ST-4 in my opinion is that the screen is not backlit and for the price should be a feature built in.
