I dove today with an HF-1 + Float and Atom with Snoot. The HF-1 was weightless

How did it “feel” in water (balance, etc.) vs no collar and more traditional arm floatation?

I was using the overall buoyancy setup i use with the Retra Maxi strobes. So it would be pretty negative with the Backscatters. The HF-1 float fully negated the weight of that strobe so the rig ended up much lighter. I loosened the arm and it would float around freely.

The Atom was still negative by 150grams or so and and the rig was noticably unbalanced. I will print a second float for the 2nd HF-1 and do another dive with the balanced setup.

I dove today with two HF-1s and the floats. They both worked well and retained integrity.

The overall rig was basically neutral and just slightly negative. However, with the two strobes extended forward of the port, the system wanted to roll backwards. With neutral floats and my ULCS float arms, the extended arms were a bit too floaty and torqued upward. With the strobes in-line with the housing it was balanced. I am going to make another change and make the floats a little smaller and less buoyant by about 25 grams each. I think that will result in just a little better balance.
