Repairs, calibration and re-standardisation

PODs are guaranteed for 2 years against faults due to manufacturing parts failure, providing the damage has not arisen from ingress of water, misuse, violent impacts, or prolonged vibration.

The standard charge for testing and calibration is GBP200. If repairs are required, we will provide an additional quotation.

POD sensitivity is calibrated and standardised very accurately in our acoustic tank during manufacture. Standardisation checks during repairs have shown that changes in the sensitivity of PODs over time are very small.

We suggest using the following guidelines for deciding whether to return PODs for calibration:

• If the POD is over 4 years old or has not been repaired or calibrated by us for 4 years.
• If the POD has received heavy or continuous knocks or physical damage.
• If you notice a sudden change in data compared to other PODs.
• If a project requires calibration certification.

When returning PODs to Chelonia for servicing or repair, please …

• contact us before shipping.
• include the PODs’ SD Cards.
• do not return any batteries.
• remove any mooring lines and ensure the PODs are reasonably clean.
• use the original packaging, if possible.
• do not use polystyrene chips for packing.
