Ian,
I am sorry to destroy any illusions. The figures are correct in the circumstances under which they are measured. (off-load)
It is an unfortunate fact that under load the figures would differ.
But do not let this cause a loss of confidence. I have had demonstrations of truck-mounted extractors where I have produced better results with my portable.
In all honesty, had the equipment been swopped, I still would have got the better results.
The most important attatchment to the extraction machine is the opperator. Having the desire to do the best job possible is the first step. Training and experience comes next.
Do you think that Derek or Ken would produce lesser results than Ivor Sucker, who left his firemans' job two days ago, and picked up the worlds most powerfull TM yesterday?
Do you think that these two dedicated individuals would let a few thousand pounds stand in their way if thay felt that they were producing inferior results with their portable equipment?
You do not need a sledge hammer to knock down a brick wall - even if it will do the job quicker than one half the size.
Take heart young man, you have already started the journey in the correct manner and you have a machine that is capable of producing end results indistiguishable from those produced by a Blazer on most jobs.
John.
