I`ve been using my camera-style/flash unit for years.Last night I was on-board a friends boat,and he had a new thingy for sparking up his stuff...I think it was made buy rapala,or berkley not positive on that.Anyway it looked like a costa-delmar sunglass case...Worked awesome,Sun setting , moon rising,One small king for our efforts.East Grand Traverse bay.Marked tons of fish,all depths.A couple more weeks it should be smok`n..See ya out there.
