R10 indoor distances off. What net are people using?

Hi everyone,

I returned my first unit after long discussions with Garmin helpdesk.

However teh replacement unit is marginally better... but still wildly inaccurate indoors.

I have carpeted the area. I have covered up everything and anything that could cause radar issues.

I have moved unit and net distances - closer and further... 

I am now wondering if it is the type of net I am using.

It seems that people that use a solid background are having less problems then people like me that hits into a net.

What are peoples thoughts?

Could teh fact that the ball slows down then slops in a net affect the reading?

I was so looking forward to winter indoor golf but I think I will have to return for money back
