Hi JoeyM,

Do you have any new information or are you still using the semi waterproof servos, and how many dives do they last?

Do you use the 3d printed release system?

Hi Mikxie,

Yes, I’m still using the hobby servos rated for one meter. The current one has gone been used underwater more than a dozen times, but all at depths less than 20 feet. Yes, I’m using the 3-D printed release mechanism that Andrew Thaler created and made available at Oceanography for Everyone.
