When I realize that Minelab has less than a fair reputation for getting work done promptly, and done well , I really think I would opt for an outside repair person to do the job if you are out of warranty anyway ..... Look at it this way ....Minelab is the one putting in these failing parts to begin with ..... I'm just waiting for a failure on mine !!.....There MUST be a better way of controlling an ongoing issue on the same detector ....not to mention that somebody must make a better pot to put in it's place ..... The machine that you will be using in the roughest conditions seems to be the most fragile , and then to have to depand on a company that is going through repair and quality control issues has me thinking about going elsewhere for my next water machine ....When my Excal breaks and it's going to be a costly repair , something else will take it's place .....or , as much as I didn't want to have to waterproof something myself, it may be a better alternative !!.....GraveDiggerMax has the right idea with his SE Pro waterproofed !!.....Jim
