TDI BH And Surf PI DF

[sborowko]

I have Surf PI DF that I has been great, though I’m thinking of upgrading to a TDI BH to take advantage of its advanced features. Can anyone here tell me:

1. Is the TDI less chatty than the Surf PI?

2. Is the TDI coil less buoyant than the Surf PI coil?

Thanks!

Hi,
I've been debating similarly. The one thing I do know is that the TDI does not have the near neutral buoyancy coil.
