I recently purchased a BH Platinum, I have not taken it out yet just getting familiar with it indoors. I bought a new alkaline battery and played around for a few minutes, battery indicator shows fully charged. After I turn it off it will not turn back on. I switched batteries, it turned on, if I turn it off and back on within a few seconds it comes on without problems, if I wait thirty seconds it will not turn back on, sometimes taking the battery out and putting it back in or changing batteries work sometimes not. Sometimes I can unplug the cord coming from the coil and plug it back in and it works, sometimes not. Anything I am missing or did I get a lemon.
