To follow up.
Once we logged on the website, Bass Pro had some funky, restrictive rules on how we could use the gift cards. They do not allow more than 5 cards to be used at a time and do not allow the purchase of larger dollar amount gift cards with smaller gift cards or the purchase of e-card gift cards with existing gift cards. We bought a Garrett AT Pro. Then logged out and logged back on and bought a Vanquish 340 with the remaining gift cards. We had to add money to both purchases but those two detectors seemed like they would fill some gaps for us. We seriously considered the Equinox 600 even though we would have had to add more money than we added with the AT Pro. It was a tough decision because by the time we added a RnB Battery and charger we were almost up to the Nox 600 price. The 340 was purchased because there was simply nothing we wanted at Bass Pro but we needed to get rid of those gift cards. We reasoned that the 340 will serve Mrs. atomicbrh well because she is rough on equipment, likes simple detectors, wanted a detector for the rare beach trips and is a good loaner to people that give us permission to detect their property. Plus, if somebody destroys it, $200 is fairly cheap in today's world. We also installed a RnB battery pack on the 340. The AT Pro may be kind of dated for the price but we never owned one before and wanted to see what it was like. Also, we feel like the AT Pro is one of the more durable detectors if we get caught in a wet situation. We are keeping our Tesoro. It has been a great detector and to us, one of the most comfortable, ergonomically to swing. The main thing is we ridded ourselves of those pesky cards from a store we do not frequent and have two more working detectors. We have not used these two detectors enough to give an adequate review. We made sure they function for warranty purposes. It is simply too hot here with too many bugs and snakes to detect. Once Fall arrives, we will begin hunting.
Thanks to all who gave us advice.
(Note: The return address label was actually from Cabela's as davidlhyde replied. Perhaps Bass Pro stocked detectors because of Cabela's input or previously existing inventory.)
