I notice and I have before it say DO NOT USE ZINC AIR BATTERIES. Does anybody know why?? 

I know Renata Silver Oxide has the most reliable Voltage could be that but Zinc Air has the largest 310 mAh so you would think it would last the longest.

I think the zinc air batteries are possibly designed to release energy as soon as they are unsealed  . Which means they discharge slowly even when not in use  in the transmitter. 

I could be wrong on that but a watchmaker friend who used to get me batteries did tell me that zinc air ones were designed to give full power until they reached the end of their life. Then they simply stopped working .

I suppose in a ferret locator that could be a bit troublesome if the batteries gave out on the middle of a dig .

Even the Silver Oxide batteries drop of quick at the end of there life but they last for ages, I usually test mine to see if there still near 1.5v. 

The only trouble I have had is from the cheap cards of batteries off eBay to be honest I've had them fail on the day I put them in. They also leak a little and corrode the copper pin in the centre of the collar which goes black, doesn't seen to happen with the better batteries.
