Good luck on the nav device. Keep us posted with problems/advances.

-gettin' late, even for me...

Enjoyed the chat LViz...thank you and good night...again soon

LViz you are right, noise is always a problem. Having a down ward looking DVL might solve these problems as you are measuring to a fixed reference. We would also have other sensors like compass and inertial to aid in the calculations. For sure it is an extraordinarily complex problem that has eluded a viable and practical solution all this time

How do you ensure the DVL sensor is "looking downward" (or upward)? Divers orient their body in different directions during a dive.

Mounting on a tank will be an issue. The sensor will have to be swapped each time a tank is swapped. How to not make this a nuisance? Mounting on the cam bands may be an idea. But you need to think about clearance issues for tanks on a day boat. The tanks are often held in racks.

Thanks for the comments GK.
When the diver wants to navigate we would expect them to have a fairly horizontal orientation. Again this is assuming that the diver isn't trying to navigate when in a near vertical orientation...wonderful zero g environment

I guess we would have to have a non obtrusive clip on-off for the device. Do you think mounting on the BCD is feasible?
