I have a Pro-find 35 coming by the end of the week. I looked at written reviews as well as youtube video reviews. My only concern is the issue of the battery compartment cap being hard to remove. I saw that this had been brought up on more than one occasion. Have any of you had this problem? Rather than worry about it, I have been thinking of a possible solution. I am thinking about applying just a little dielectric grease to the threads on either the cap or the pinpointer. Opinions? Suggestions?
