Compact Budget Chronograph

Just checked my little Chinese Midget against my Caldwell G2 and the Chinese chrony is running about 2.5 mps or 8 fps faster than my Caldwell!

Close enough for me? Gotta be quick with reading the Midget, cause it only shows the meters for a few seconds. I learned quick I had to write down the midget numbers before the G2 numbers or the numbers on the Midget would be gone back to zero in the short time it took me to write the numbers for the G2.

hey , yall , i'm noticing much slower reads when i shoot with the muzzle about one inch from the plane or first sensor.....when i scoot the muzzle back to around 8" my soft-tuned .177 gamo shadow 1000 goes from 152 m/s up to 262 m/s...... have you guys found an optimal distance away from the midget box to get your most accurate readings ? i know 6" up and 6" out usually does best with my (outdoor only) green f1 chrony , and about 12" back for co2 guns because the gas cloud throws it off...............but how far back have you found to be most accurate of speed testing non- co2 guns ? .......( i can REALLY see my little china box getting shot now :-( ).......... and have yall found if any lighting from outside the little cube effects the readings ?
