CORRECT CLOSING OF BV250/BV300 LIDS:
Incorrectly closing the lid has resulted in at least one incident of a bear gaining access to these models. These incidents are reported to the rangers, and the Sierra Interagency Black Bear Group keeps a tally of these incidents. If they feel the number of incidents is excessive they can revoke the approval of that model of canister.
We point out that this can happen in an insert in every unit we sell. The insert points out that this is easily remedied; if you see the lid hit the top of the bump, simply press in with your finger on the lid and it will move inside the housing stop bump. You can then continue tightening the lid until you hear that “snap” which tells you that the lid is closed correctly. The lid will also be touching the housing so there is no gap between the lid and the housing. If you have an oversize lid and you ensure you close the lid correctly, you have a canister that has withstood attacks by 800 pound Grizzly bears successfully. If you do not close the lid correctly you have a vulnerable canister that may fail during a bear attack.
Please ensure you look at the lid and housing when you close these model BearVaults so that you are sure it is correctly closed. We plan on automating the lid manufacturing process this winter so that there are no longer these size variations, but in order to do this we need your help and awareness of the issue so that you correctly close the BearVaults . We are partners with our customers, and we need you to correctly close your BearVaults if they have an oversize lid or else you all may lose the option of buying a larger, lighter, easier to use bear canister.
If you have a friend who uses a BearVault, please pass this on. If you would like a copy of the insert, please email us at firstname.lastname@example.org .
In 2007 one or more bears at Marcy Dam in the Adirondacks learned how to open BearVault models. The bear(s) opened the lids by pressing in the snap on the lid with its canine tooth, unscrewing the lid past the housing lock and then opening the unit. There were no problems with BearVaults outside of this area.
In response to this a new lid was developed for 2008 which had two snaps on the lid which both required being pressed in sequentially- this is the model BV450/500. Testing was conducted during June and July 2008 at Marcy Dam and Lake Colden. We now have the test results. Surprisingly, the bear(s) pressed in the first snap with its incisor, rotated the lid and then pressed in the 2nd snap with its incisor and opened the lid.
The DEC believes that this behavior is unique to this bear(s) as they have not had any incidents of this type of failure of BV350 and higher models outside of this area. They also are doubtful that this behavior will migrate to other bears and BearVault has seen no evidence of this happening. There have also been no problems whatsoever with BV350 and higher models anywhere else in North America.
Accordingly, BearVault recommends against using BearVault canisters in the Lake Colden/Marcy Dam corridor and the Johns Brook valley as these are within the bears' territory. You can freely use BearVaults elsewhere.
