I have a barely used MiniLink REAL-Time Transmitter Kit(MMT-7707NA) for sale. I used it 3-4 times.
It is watertight:
-Can be worn while swimming, bathing, or showering
-Withstands a depth of 8 ft for up to 30 minutes
SenSerter® insertion device
2 AAA batteries
-Provides 14 days of continuous use on a full recharge
Retails for over $1500; asking $500 OBO
I also have 9 Sof-Sensors (MMT-7002C). They are expired so I will throw these in for free.
