For some reason, the antenna on my Tritronics Classic 70 G3 EXP disappeared. I admit it had been some time since I checked the security of the antenna. WARNING! When you are in the field, it is a bad time to lose an antenna, with no back up. My options at this point are: I can order one from Tritronics and get it 2 days later or drive to Bismarck (240 mile roundtrip) to purchase another one. Two mistakes I made: one is not checking the security of any antenna I have, pre-hunt or every day. Second, I should have extra antennas on board for the eventually of loss or damage to one. Actually, I did have an extra....last year in MN, I sat on a rock and heard a "crunch". It was the antenna on the TT which had been dangling from a secure holder on my belt! Oops! But, I had a backup antenna in the truck and all was well. Do you think I would order another set? Of course not..... I have double backup antennas for my Garmin... and today I will get another Tritronics antenna at Scheels, in Bismarck, when I go to get my wife at the airport. Dude, it's cheap insurance. Do not go in the field with out extras of everything- any part that can break, wear out, or get lost..
