I used a 60 CSx for years. Own 2 now and love their accuracy. However about 2 years ago, I decided I needed a paperless machine so I bought the 62s. My main complaint is poor battery performance. I have the screen set to time out in 2 minutes and have done e everything I can think of to help with battery life. Also, whenever batteries do need to be replaced when I do a compass recalibration, the 3rd step is unsuccessful more often than not. I really dont want to have to use a smart phone to get info needed and I dont want to spend 400 bucks on a new machine. Any suggestions appreciated.
