TAC 15 Crossbow Downrange Velocity - Chronographed?

I got 406 fps with an 85 grain fieldtip at the "muzzle". I was unable to get a reading at 100 yards when I tried. Does anyone else have a reading?

CED M2

5 shots but the only one that registered said: "6000".

For what it is worth: I could not get a CED M2 to read PSE's arrows shot from a TAC-15. I got either nothing or obviously wrong readings in 4000 - 6000 fps range.
A real disappointment.

Time to try a different Chronograph.

Gents,

On page 6 of the Manual for the M2 chronograph it says:

If you plan to shoot a shotgun or archery arrows, read the appropriate section for
further details.

And on Page 12 it says:

Shotgun / Bows
The CED M2 Chronograph can be used for shotshells. The system measures the velocity of the front pellets
in the shot string. A closer screen spacing of the tripod of (3 to 4 ft.) three to four feet from the muzzle of
the shotgun should be used. This means that the FIRST Skyscreen sensor should not be further than 4 feet
from the end of the shotgun. In the case of bows, make sure that the Skyscreen sensors are far enough away t o
allow the arrow to fully leave the strings of the bow before the tip of the arrow reaches the first sensor. Blunt
arrow tips (rounded or flatter nose) work best! Remember, the sensors need to see a change of light in order t o
read the arrow.

Hope it helps!

Re: TAC 15 Crossbow Downrange Velocity - Chronographed?

There is a new product just released called the Velocitip. It is a 100 grain electronic field point that measures velocity, kinetic energy and momentum both at launch and down range at impact. It also give you time of flight, drag coefficient data as well as group averages and std deviation. You can check it out at Full Flight Technology :: Velocitip Ballistic System, Archery Equipment Evaluation and Performance Testing, Arrow Acceleration Sensing.
