Updating transducers

Hello.

I need some advice on updating transducers for a 32 ft sailboat we use for coastal and Caribbean cruising.

Current configuration:

ST60 Wind
ST60 Depth
ST60 Speed
Unknown transducers, (circa 2001) one speed, one depth.
For navigation we run Navionics on our iPad.
Installing an EV-200 Autopilot

Questions:

Are the transducers that run the ST60s out of date or otherwise in need of upgrade?

Which transducers would you suggest?

Should we want to switch to a Raymarine eS MFD, will our current transducers be sufficient?

If not, which would you suggest for integration into an MFD in the future?

We will be hauling the boat soon for painting and repairs and could replace transducers at the same time.

Thanks for your help,

Nancy Bartlett
