I just ordered a new alkaline pod today for my xcalibur 2. Just wondering if anyone else here has one and how they like or dislike it. How long will they run with fresh batteries? Is there a problem with the alkaline running to low of voltage after a few hrs., making it false or act similar to the NiCad when it dies? Hope I made a wise choice. I can't imagine minelab selling them if they were that bad.
