I recently offered an Explorer battery pack for free to the first person to respond and Elton was that first person. After making arrangements to ship the battery to Elton, he found out a lady just got an Explorer and it did not come with a rechargeable battery. Elton asked me if it would be OK to pass the battery on to this person. I was pleased that someone who really needed the battery could be able to use it. The battery is not perfect, but I was always able to get 7 hours or so of detecting out of it. This person will not have to buy alkaline aa batteries, but from what I understand, this lady does not have a wall charger. If anyone has one laying around, please contact Elton and maybe he could forward the particulars to this person. Thanks Elton!
