So ive had my first provari 2.5 i think about a week now and this happens a few times a day. I thought maybe its letting me know battery is getting low but right now battery reads 4.0. Sometimes when i fire,i just doesnt. It catches me off guard because nothing happens as im drawing. The light comes on by no fire. No error message,just nothing.When i fire again right after it does fire it. Wondering if this is because i dont have my nautilus tight enough? There is a slight gap but i didnt want to tighten too much,i think its snug,but there is that gap? Ive been using this only since it came and love it otherwise,even ordered my 2nd already but it is bugging me cos ya know,its provari.
