The effects of electroshock fishing on underwater loggers

Although we have not tested this, we have run into incidents in the past where customers have left data loggers in this situation and have not had a problem. On the other hand, we have also had customers whose data loggers stopped recording. It is a gamble and strictly up to you. We do suggest that you pull the data loggers up to be on the safe side, or at least check them after to make sure that they are still recording.

How often do temperature data loggers need recalibration and/or servicing?

All sensors drift over time and they can be tested in a controlled environment to make sure that they are running within the specifications outlined in the User's Manual. You can use methods such as a simple ice bath or an environmental chamber to verify your device is operating correctly.

Waterproof shuttle for beginners

These photos illustrate how to use the Waterproof Shuttle and a data logger together. We are showing a U22-001 logger for this demonstration, but the same steps apply to any USB-based optic logger. These steps are necessary for initial deployment of a logger and when communicating with the logger directly.

Discharges may occur when there is a charge difference between the data logger and a cable being connected to it or when a person touches an exposed jack.
