I have both a gen1 and gen2 panhead. Gen1 is smooth. Gen2 has hesitation or jerks when going to pan horizontal. For example, looking thru binos or tripod, start to move horizontally, as I move it jerks, enough to cause you to loose keeping your line of sight in the glass. I've tried manually moving the head around many times to break it in. I then sent it back to Outdoorsmans and they said it's within spec. I won't use it this way. Anyone else with this issue?
