Went to a toboggan hill, and detected for two hours. In the past, using rechargeable NiMH batteries required me to attach a hot pack on the electronics to prevent the batteries from discharging from the cold. Not so with the APEX. I started with 4/4 bars battery indicator, and after 2 hours in cold temperatures, I still ended with 4/4 bars. Plus, I already had some previous time on this detector for about an hour, without recharging it.
