Ive had other `WATERPROOF`machines in the past and never had a water problem and paid less than half the price.Dont get me wrong...I love the 3030 and the things it can do.But when it comes to being waterproof it missed the mark....Ive had to put automotive battery terminal protector grease on the battery terminals even with the new style battery and seal ..The USB port is also a weak spot begging for Silicone on the threads.You would think that for the price of the machine it would be truly `WATERPROOF`without needing any mods or help from the end user..But its barely `RAINPROOF`!....Since the introduction of the Explorer in 99 Ive hoped for a waterproof one. Wish they would have done a better job!! Ralph
