Sorry if i look weard and stupid, but i am trying to understand. According to my study expected cost of gpz is not more 1500usd as they are manufactorer, as sales is 33m lets say 50% of them sales was gpz which is about 16.5m and if the cost as i calculate it is 1500usd should be only gpz profit about 12m and others small detectors lets say is about 50% so its about 6m should be total profit about 18m only from detector business do you think guys expances and taxes for 6months can be about 12m - (this is only detector business) how about radio communications - really i am keep reading the report and cannot understand it.
