Possible DOA Caldwell Ballistic Precision Chronograph?

[ChemistShooter]

I bought a Caldwell Ballistic Premium Precision Chronograph off Amazon and paid for a new one. Box showed up half-ass sealed on one end with clear tape, which made me think this was somebody's returned unit.

I set it up in my apartment. Installed the IR lights. The little red lights came on, and it went through its start-up sequence.

And surprise, surprise, it doesn't work. At least as far as I can tell. I set it up in my apartment, regular light, no flourescents and tossed some some of the cast bullets I just bought directly over the sensors, front to back. And nothing, not a twitch. Damn thing couldn't detect a cannonball. I went crawling through the manual, but couldn't find anything. It'll go through its start-up sequence, but that's just about all it will do. Sometimes it'll throw an error message. I wiped the sensors with a Q-tip, no effect. Tried the manufacturer's Website, no revelations there.

The smartphone app also will not detect the unit. I'm guessing it got dropped somewhere along the line.

Unit's probably DOA, but I thought I'd ask here and see if anybody knows something I don't about how to make it work.

I shoot a rubber band off of my finger and over both sensors for testing. This function testing works OK for me.

Very possible it's defective. I'm on my 3rd one now.

Tried it in the morning, no light but diffuse sunlight through the blinds. Still couldn't detect a bullet. It would trigger about half the time if I ran a flashlight over the sensors, something the Website recommended. My results indicated the rear sensor had lost most of its sensitivity.

Back to Amazon for a replacement. Hopefully I'll have better luck. If not, move up to a CED M2, I reckon.

Thanks to all.

You can go straight through battenfeld for a replacement as well. That's what I have done they are very helpful.

[ChemistShooter]

Ah. That's what I'll do if this one doesn't work. Surely the factory will have one that works.

You have to take it outside and shoot something over it like an arrow or a bullet. Its not made for throwing stuff over. Mine works perfectly when I shoot over it but if I through something over it nothing happens.

Mine arrived today - also from amazon. The box did not appear particularly well sealed, but everything inside appeared new.

I tested it by flicking a flashlight beam across the sensors - I was able to get it to read 9-13 fps ok

Plugged it into my iphone - app worked a series of flashlight passed averaged 10fps with SD 1.5 ;-)
