Its just clever advertising by the marketing men.....a lot of people are just sucked in by the promise of improved features and performance, most of which rarely improves finds rates.A good example is the xp deus and the pevious model the goldmax power.
Over here in Britain,the goldmax power ruled the roost on our ancient sites,excellent seperation and depth,iron volume and silencer,multi tones and no screen.......it sold like hot cakes and it is still an incredible machine on iron infested sites.
Along comes the deus......wireless,a control box you can slip in your pocket,loads of programs blah blah blah.Overnight the deus became the no1 machine and everyone jumped on the bandwagon.Is it better than the power......in my opinion no,the power can still hold its own against the deus,there is even a goldmax power program on the deus and a lot of deus owners use this program most of all.Also many deus owners regret selling their gp to fund the deus and are returning to their old faithful.I've even seen you tube reviews comparing the two machines that are total rubbish showing how much better the deus is in amongst iron than the gp is.......i'll do any test against the deus with the goldmax anytime in real world tests.
Basically,it is all the features that drive people away from more simple machines,they think more features equals more finds and thats why simple machines like tesoros etc suffer in the market.Put two detectors in front of somebody and most will choose the all singing,all dancing model regardless of performance.....thats the power of marketing.
I'm glad that people buy the latest vid machines as i know a lot of them are missing a lot of targets by relying on ridiculous programs and inaccurate target info.....more goodies for those who are willing to dig more targets.
