Deerslayer!

If your not using your rangefinder for any period of time,do take the batteries out .I left mine last season with the batteries in it and it's now been sent back to Bushnell ,the batteries corroded the terminal's and started acting really wierd and then I couldn't depend on whether it was going to work or not .All this because I left the batteries in it . It sound's as though you might not have a whole lot left over to open for Xmas,now there will be no excuse for a miss LOL
