Not too sure where this detector is going to fit in the market, many of the features are as the Deus and other offerings.
In the UK the Relic never took off here, the Racer sold well but you take a big hit when you sell it 2nd hand.
The Impact being online upgradable will help, but only if the updates are any good.
They do however have a good customer service at Makro/Nokta, maybe more out of necessity after all the issues with the Racer!
It would be interesting to see some more of the spec for the Impact.
