Walt Posted July 5, 2017 Share Posted July 5, 2017 I received a 521 Tab mini with a CoilMaster kit and I purchased a 521 Tab "maxi" or whatever. Not the latest two battery flying saucer thing. Both testers will take maybe a half dozen pulses for dry burning and then show low "battery I assume". Not a big deal I guess. I can use them for build stations and to measure resistance. I can always use a mod to dry burn. Just annoying, that's all. Link to comment Share on other sites More sharing options...
