laser incidence meter

[cvn68]

Hello,

I'm from Germany and I have bought a laser incidence meter from Great Planes at ebay.

http://www.greatplanes.com/accys/gpmr4020.html

Unfortunately I don't get any reply from theGerman importer.
Neither Great Planes gave me an answer. So I try to get some help form here.

I needs some new batteries for the laser pointer but I don't have the old ones

Can someone please tell me what type and voltage of batteries are needed?

Any help is appreciated!!!!!

Thank you very much!

regards
Helmut

You'll need two button/watch type silver oxide cells

Part# right on the battery is GP393
Great Planes Part # in the manual is GPMR4022

I use hearing aid batteries in mine. I get 'em at Wal-Mart (what is the German equivelant to that?) They come in a round plastic despenser and seem to be less expensive than a similar battery off the battery shelf in the same store.
