I was talking more like every time I find one u have to dig a big hole dump a ton of water and make a slurry
That is a terrible way to go about it indeed.
I have an apera ph60S thats bad ass. I also have a bluelab thats very good too. You make the hole first using a tool (the Apera sold seperately, the bluelab it's the probe cover) then gently insert the meter probe and let it take a reading. I do it ALL the time. Works great. They read liquids as well as the soil/coco. I could stick my apera in a piece of chicken and get the pH lol.

Thats the bluelab. The prices were going up and now it confirms why. Their stock was running out. But anyways thats the model.
The Apera pH60S (S = Spear Probe) costs more than the pH60 that does liquids only. The spear probe just costs more and is fragile. Always store them clean and in the KCl storage solution (in their probe cover). I consider a good soil pH meter to be my most valuable tool. If you get an Apera I suggest going directly through them.
