hi all i hope someone can advise me,i have owned a sov g.t since they came out +before this an xs2apro,really pleased with there performance ,then i bought an excal 1[blue headphones]so i could water hunt but was not pleased with its performance [maybe half as good as the sov]sent it back to ireland complaining twice ,they said it was working as it should,i thensent it back again because i thought it was useless then they sent me an ex demo model with yellow headphones in exchange,about 3 years ago.i have tried +tried with this one ,but am i just unlucky because i think the performance is still poor compared to my sov g.t..i can afford to buy a new excal 2 but i am scared of it not performing as good as my g.t. ,so honest opinions please is the excal 2 really any good +how much difference is there between it + the g.t. p.s. just returned from a week trip to europe used the gt,in the water ,signals were about the same as on the wet sand ,then used the excal+the signals not as good and also nowhere near the depth ,thanks for your input alun
