| [1] Manually adjustable hopping interval rates (0.25 seconds, 1 second, 30 seconds and auto-hopping) Channel hopping will increase the number of messages received, in comparison with single channel receivers. However, part of some multi-AIS messages may be lost, due to the hopping nature of the product. If both the quantity and the completeness of AIS messages is important to you, we recommend the dual channel receivers.
