This is a used Neptune alti-2 audible altimeter.  I purchased it 2 years ago for $249.00 and haven't been jumping so I figured it is time to get rid of everything.  It has less than 40 jumps on it so it is like new and comes with the wrist mount and outer armor to protect it. 

***NO RESERVE SO GOOD LUCK BIDDING***

These are the features to the newest Neptune but everything looked the same to me.
