Instantel Blastmate II DS477.

Device powers on and it seems like it works fine.

Unfortunately, I don't have experience with devices like this and don't know how to complete proper testing so I'm listing it as "For parts or not working".

However, as you can see, calibration sheet is included with the device.

Everything you see in the pictures is what you get.

Please review photos and let me know if you have any questions.

If you are interested in more of these devices I have several more in stock and I'm happy to work with you on a deal.

Item sold as is - NO RETURNS!

THANK YOU!
