It has been raining for a week so I was doing some shooting on my short range(in the garage). I was thinking it would sure be nice if I could use the chrono in here and as I was waiting for a heat treat to normalise I thought I would try the chrono. Like they say, under the florescent light it flat won't work. I had it on my tripod and there was a desk lamp beside it so I tipped it on it side and aimed the sensors at the lamp. I tried again and this time I got results. They were a little random but I was on the right track. Shooting through the wires when it was sideways was tough so I needed a lamp hanging from the ceiling. I screwed a couple of light sockets to a board and made some hangers out of string. Couple of screw eyes in the ceiling and hung it up. It worked better but with the short range the arrows were flopping around and the fletching hit the shade wires a couple of times. I needed something plastic the same as the shades. Over in the recycle pile there was a stack of ice cream buckets, perfect. I slipped the handles over the "light fixture" and took the wires and shades off the chrono. Turned out the florescent lights and waved a stick through the sensors, 26 fps. Tried again, 27 fps. Tried the bow, 165 fps. Did about 10 shots all in that area with two wild ones, one 375 and one at 80 or something. Then I put a mark on the arrow about 6" from the tip and slid an "O" ring down to it so I could could have an easy, repeatable draw. I shot about 15 or 20 shots except for another obvious couple of wild shots all within 2 or 3 fps. I'm sure the wild numbers are me just not getting the arrow straight over the sensors. If I wave a stick through it I can stand there waving the stick all day and they will all be around 30 fps. I had to buy a light socket, some 60 watt halogen bulbs and some wire. Came to $20. Don't laugh, here's a picture.
