Our DROPs use the standard CR2025 battery coin cell which can provide 3-4 months of battery life. If you want, the DROPs can use a CR2050 battery which can get you an extra month or two of battery life, however you will need to change the battery door and purchase a Kestrel 123 battery door for the DROP to make it fit

Station pressure is used in practical applications outside of weather. For example, ballistics, air flight, and drag racing. This is the unadjusted atmospheric pressure felt at your current location.

It will depend on if you want to integrate just the weather data or both the weather and ballistics data. If you need the ballistics (and/or weather) data, please send an email with a high level description of the project to Tech Support Email.
If you just need the weather data protocol, you can fill out our Technology Agreement found here: Kestrel Technology Agreement

Our article Understanding Pressure, Altitude and Density Altitude talks about Altitude and Barometric Pressure in great detail. The article also describes how to utilize your Kestrel to take these measurements.

Set the logging rate to the max, 12 hours. You could set the data refresh rate to its max, 1 minute, but that will only have an effect when connected to the DROP. Also if you connect to the DROP in colder weather, this will affect battery life more than in warmer temperatures. If possible, warm up the DROP before doing a data upload to Kestrel LiNK to help with battery life.

The Stats page shows the data that is currently stored in the logger on the DROP. Currently you need to disconnect and reconnect to acquire more data, so the Refresh is useful only during an active download. You can hit the Refresh button to populate more Stats as they are in the process of being downloaded to the application.

This is really just personal preference. If the DROP name is related to its location or purpose, then obviously changing the name would be helpful each time.

Yes. Once you make the settings to the DROP (custom name, logging rate, data refresh rate), those settings stay with the DROP itself. This means that all anyone else would have to do is download the Kestrel LiNK) app from the Google or iTunes App store and connect to the DROP to access.

No the DROP will not connect with the Kestrel LiNK Ballistics app. The app does not have a ballistic solver in it so you need to have a 2700 or 5700 in order for it to work correctly. However there are other 3rd party apps that will work with the DROP. Here is a list of them: 3rd Party Apps

A data point is a collection of all the measurements at a set point in time. In other words, if you record the temperature, humidity and pressure at 12:00 AM, all these numbers will constitute a single data point. Thinking of a data point as a “data set” may help.

This is dependent on a setting for the DROP in the Manage Data Log section. If you go to Manage->Manage Data Log, you will notice a Wrap Log toggle button. If the Wrap Log toggle button is slid to the right (indicates ON), then the oldest logged data will be overwritten when the data logger is full. If the slide is to the left (indicates OFF), then no more data will be collected when the data logger becomes full.
