The 6600 V2 is a submersible instrument used for real-time environmental monitoring . Features the largest water quality sensor payload, including 4 optical sensors, and integrated anti-fouling wipers.
It measures the following parameters parameters: dissolved oxygen, turbidity, chlorophyll, and blue-green algae; additional calculated parameters include total dissolved solids, resistivity, and specific conductance.

High perform
ance, rugged marine GPS with US g2 coastal charts, 3-axis compass and barometer GPSMAP 78Sc is a  powerful marine handheld units that now feature color mapping, a high-sensitivity GPS receiver and a built-in MicroSD card slot for loading additional maps. A whopping 1.7GB of built-in memory provides cutting-edge performance, and you can also add maps from Garmin’s wide array of detailed marine BlueChart g2,topographic and City Navigator road maps. Plus, the 78 Series supports Birds Eye Satellite Imagery, and is compatible with Custom Maps, free software that transforms paper and electronic maps into downloadable maps for your device.The unit features a worldwide basemap, and the 78Cs comes with built-in BlueChart® g2 coastal charts for the U.S. And with the 78 Series, you can share your waypoints, tracks, routes and geocaches wirelessly with other compatible devices. They’re completely submersible and float if dropped overboard.

Reflectance measurements are obtained based on the object-leaving radiance and downwelling irradiance at multiple wavelengths using the GER 1500 Spectroradiometer from Spectra Vista Corporation. It has under water enclosure for underwater reflectance measurements. This case allows us to make measurements of different bottom types, like coral reefs.

The Trilogy Laboratory Fluorometer is a compact, multifunctional laboratory instrument that can be used for making fluorescence, absorbance, and turbidity measurements using the appropriate snap-in Optical Module.
In this lab fluorescence modules are available for discrete sample measurement of various fluorescent materials including chlorophyll (in vivo and extracted),  cyanobacteria pigments, CDOM,
