Got a great pop up net for the garden. Got a mat to use with it, but although the right size, it's waffer thin compared to the heavy duty ones at the range.

Short of "theft" anyon know where I can buy a decent one for sensible money?

How about asking your local driving range if they could make a suggestion, maybe they have a spare mat you could buy.

I had the same problem trying to find a decent driving mat. Sent 2 back because they were very poor quality but have just received one from on-line golf this week and it should to the job. Costs £50.

I've heard they're very expensive (hundreds per mat), so theft may be the best option and safest considering the typical gormless sods that work in a driving range.

Should read "do the job".
