Tension issue / technique question about portable stringing machine

You can't get an ERT 300 anymore. These stupid phone apps are useless aren't they?
Do you know what does an ERT300 do/provide, and the difference to the stupid phone app you are referring to?
I’d work on the consistency before looking at those devices/apps. Lol

It measures the stringbed stiffness. With a phone it depends how far away the phone is, how hard you tap, what you tap with, the background noise. You've got about as much chance of being accurate with a phone app as you have playing pickup sticks with your butt cheeks.

Maybe some more experienced stringers can chime in, but I don't think it's good practice to use a starting clamp for crosses with flying clamps.
I would suggest using a starting knot and then tension the top two crosses at the same time.

Explained very clearly here:
The stringer in this video is confused about what is a main and what is a cross.

The distance the phone is away, how hard you strike the strings, and what you tap with impact volume not pitch. The pitch is what drives the reading. The volume simply drives the tools ability to sense the pitch or not but does not impact the value.

As far as background noise I use the tool where I string racquets which is in the basement and have no issues with background noise and whatever noise that is in my dungeon is consistent.

The biggest variable I see is the String Factor and if one is consistently using the same String Factor for the same string they will get the same reading on the same racquet for a given tension.

The ERT300 guesses what the SBS is by sending a frequency into the string bed. How it comes up with a number is suspect since it does not ask for size of racquet face. It does not push down on the string bed in the same manner as a StringLab. RT does need a quiet environment to be accurate. It also needs to know face size and a really accurate string factor(s). Given this data, it is very accurate IME. Most users don't measure their SF correctly.

Ok I realized that I made a big mistake when weaving the first two crosses... o_O
That's why the crosses was so loose and the entire string job so bad... Hahaha!!!! :-D
Now I just finished my second string job and it seems to be far better!!! :cool::p
The only problem I had was that the flying clamp slipped when pulling the second main... It slipped not too much but it slipped... And the string was a little damaged... I string today at 55lbs compare to 51 I did the last time... I think it will be difficult to string tight with my flying clamps... I will try to clamp harder next time but if you have a solution?

Ah, so what you are saying is that those stupid phone app measures the exact same as an ERT300, because the distance and how you tap are the main variables?
