Hi Kidbeey,
I think you are referring to the control box and battery cover on the CTX3030; said cover is a pup out of the GPZ7000 cover that the better and self designed and made a couple of years back. At the time there were/are some very well made covers for both machines, they have a similar foot print, the 3030 being a tad shorter than the 7000 due to battery dimensions. The aspect of the above mentioned covers that we did not like was that the various parts on the control box cover folded up rather than down, the problem with these designs is that they tend to catch dirt and sand etc and thus defeat the purpose of having a cover on the detector. Having convinced the better half to sew both covers, second time for the 3030, divorce loomed, hell hath has no fury compared to she who has to be obeyed when trying to put these covers together, will she make a third!!!!!! "NO WAY" she tells me.
Cheers, SinHof.
