It's the Hi Bebe BT-200 fetal doppler.

Works great. I loved this thing. Sad to sell it but I need the cash instead for the babes.Chat Icon Chat Icon It has batteries but its going to need new batteries.

DH bought it off ebay. Selling for 80 it comes with a 250ml tube of hospital grade ultrasound gel that I bought for 30 bucks and maybe used 2x. Its still full.
