What is the recommended deployment configuration for an AquaPro HR?
FollowThe main setup configuration to be considered when deploying an AquaPro HR are:
- Physical configuration of the instrument, i.e., downward looking shallow or deep water and upward looking, please refer to What should I take into consideration when deploying an AquaPro HR? as this is the most important item.
- For the new AquaPro HR 2 (1 and 2 MHz), a minimum blanking distance of 0.1 m is recommended. For the old AquaPro HR 2 MHz, a minimum blanking distance of 0.1 m is recommended and for the AquaPro HR 1 MHz this distance increases to 0.4 m. Values between 0.25 m and 0.4 m can still be used, but the data should be looked at carefully.
- Burst sampling or continuous sampling depends on the project. The main difference with burst sampling is that the user can specify exactly how many individual samples they want to collect in each measurement period, as opposed to averaging over a certain time period.
- Battery requirement changes dramatically with the setup: number of cells, profile range, average interval, blanking distance, compass update rate and measurement load. The user should always assess by using the Deployment Planning software to have insights and calculations on battery and memory usage. As part of the Aquadopp platform, the AquaPro HR fits up to 2x Alkaline batteries (2x50 Wh), to 3x Lithium-Ion rechargeable batteries (3x75 Wh) or 2x Lithium batteries (2x165 Wh). It can also be connected to an external cannister. Remember that the software calculates battery consumption based on batteries provided by Nortek. We recommend using Nortek-branded batteries for safe and reliable deployments.
