I have the same unit, have had it for about 3 years. (Replaced an earlier one that I dropped.) It has an accuracy of about 6 feet on most of the geocaches I have worked. I am using the wgs84, and no offset adjustment. It's memory died and when the regular batteries were replaced all information was lost. Lowrance gave absolutely help except recommend buy a new one. Finally got mad and took it apart. It has a $3.00 battery for memory backup. Replaced it and now memory is fine. Good luck on the unit, you may have to work the offset adjustment. Allen
