ADA corner weight gauge...worth it?

Looking to re align my 1973 Porsche 911.
Alignment is easy until you come to the corner weights. Every angle can be adjusted on a 911 if you have the equipment.
One part I don't have is the corner weighting gauge.
Today, most use the digital platforms and read outs. I am wondering if the old fashioned ADA type gauge can give reasonable results.
I would like to get the 1000Kg car to about 5 Kg across the car which might be asking too much.
Anyone with real world experience of these gauges and accuracy achieved?
You can still buy them new, so they can't be too bad?
Graham.

I've got one and can get to 5kg on an 860kg car. You just need to take your time, ideally with an assistant.

I used one for years, when I finally put the car on a set of scales, it was spot on.

I always put a piece of paper under the tyre. When this came free I knew the tyre was just off the floor. This means you absolutely minimise the wheel lift and also do the same thing on every corner.

Graham, I have a couple of caravan weighing devices, digital readout and can weigh up to 1000KG each, which I have used before for this process. If you'd like to borrow them to try you would be welcome.

Thanks Dave.
I think I will take you up on that as it will be easier in the long run.
I have also been offered a loan of the ADA gauge but not sure yet of the capacity.
The 911 is 1020Kg, each front corner is about 200Kg, quite high for an ADA gauge, your scales are man enough!
I should be needing the scales in about 2 weeks time, so will call and pop over if all is ok for you. Would need them for a couple of days.
Old 911's are tricky to set-up. The pro's take a day.

Just buy 4 of these and you can weigh a car up to 1000kg - cost is less than 90 quid

Edited to say - if you car is very front/rear heavy it won't work... sorry - but it might be useful info for someone reading who has a lighter car.

Yep - that's where the assistant comes in handy unless you're an octopus.

The 911 is 1020Kg with a 60/40 Rr/Fr bias.
Thus, roughly the rear is 610Kg, 305Kg per corner, the fronts less so.

It has been suggested that you have the card trapped under the tyre.
Fastened to the paper is an elastic band, tensioned to the floor. When the tyre is 'just' free the card moves as the elastic pulls it so giving the repeatable 'freedom' point. You can see this and read the gauge scale.
Nice trick I thought!
