Yes, solids should perform about the same as standard copper-jacked rounds. If the round is made out of something that has very low electrical conductivity (like lead) you may have to make the device more sensitive by changing the bullet type setting, but most solids should work with the default settings.

The MagnetoSpeed display unit saves a CSV (http://en.wikipedia.org/wiki/Comma-separated_values) file which can be opened by most any spreadsheet program or text editor. If you want to start a new log file, simply use your computer to rename or delete the LOG.CSV file on the micro SD card and a new one will be created. Renaming the file with the date is a good way to keep track of your data.

Yes, the MagnetoSpeed V3 was designed to work with larger barrels and suppressors up to 2 inches in diameter. The Sporter was designed to be used with rifles up to 1" in barrel diameter. If you require a custom lab setup for rail mounted guns please contact us for details on our custom services.

Magnetospeed chronographs can work with both lead and steel projectiles, though the sensitivity may need to be adjust for lead-only rounds. The same applies for shot loads, however we do not recommend use with #7 bird shot and smaller due to a drop in accuracy.

The main difference is that the Sporter can fit on barrels from .5" to 1" in diameter. The V3 can fit on barrels and suppressors from .5" to 2" in diameter. Use this comparison chart to see major and minor differences.

No. The V3 rail adapter can only be used with the V3 bayonet.

Yes. All bayonets and displays are compatible with each other.

Please reference the QUICK START guide in your instructions. Make sure that you have the thumbnut at the very bottom of the threads before mounting the bayonet on your barrel.
