Tangaroa consulting is now supplying Cobalt connectors and cables from Blue Trail Engineering in the UK.
The connectors are an excellent addition to the Blue Rov allowing easier connection / disconnection of items and helping to keep things water tight. The M10 thread is a direct fit to the Blue Robotics range of enclosure end caps.
Here are some pictures of the 18 Hole end cap fully populated.
Let me know if you require any further information.
All the best
