Good morning everyone,
Deploying 'old' tags can introduce overlapping Tag ID's in the system that are impossible to distinguish once deployed, and can have serious consequences for your data. In order to avoid this it is critical that we track previously un-deployed tags (purchased in 2015 or 2016) that users are intending to deploy in 2017.
If you have old tags that you intend to deploy in 2017, please let your contact at Lotek or Biotrack know as soon as possible, and include the specific IDs and burst rates of the tags you intend to deploy. If you're not sure about these parameters, you can consult your project tag list on motus.org.
In the long-term maintaining up-to-date metadata on motus.org will be the best way to track and avoid these issues. Steps are also being taken to dramatically increase the number of unique ID's available in a given year, but that will take some time to implement.
As always, don't hesitate to contact us if you have any questions.

In regards to the email about deploying old tags, does anyone have experience with deploying 1-year old NTQB-3-2 tags (12.7 s burst)? I was wondering how reliable the battery will be after sitting for one year in regards to how it may affect the study. We are following Lotek's instructions to keep in a cool dark place and turn on/off every 3 weeks.
We deployed some old 0.29 g NTQB-1 tags a few seasons back. We kept 2 back and monitored them every day. They still lasted beyond the guaranteed original life. I suggest keeping back a tag or 2 to compare.

If you support work/life balance then please refrain from sending work emails to your colleagues after hours, on weekends and holidays. It makes them feel obligated to reply, and that they too should be working. Saving a draft and sending first thing on the next business day works very well. If you or I need to work after normal working hours there is no need for the other to know.
