Default Upgrading from a Garmin 4212 to a 7612xsv

I currently have a system that has a 4212, GSD24 with a B60 transducer, and xHD24 radar. Will Garmin be coming out with any kind of mounting adapter st allow you to drop in the 7612 into the 4212 mounting hole? Does the 7612 traditional sonar 50/200khz have better spec's vs the GSD24 or should I just network the GSD24 to the 7612?

Considering you are using a single element 600 watt B60 you will have the same results with the 7612xsv as with the GSD24.
No reason to then use the GSD-24..the built in 1 kw sounder of the xsv is excellent.
Going to the 7612 ..you then have side and down vu and built in wifi.
Later ...if you take out the B60 and use the CHIRP B75..you will see a marked improvement.
The CHIRP B75 will retro into the B60 hole...just open it up a tad.

Youll be upgrading to Chirp which means another transducer. The gains are well worth it. Not to mention faster processor, full pinch to zoom, greater refresh and redraw rates.

Does the Chirp B75 Chirp fit into the same size cutout of the B60?

B60 and B75 are the same size but....
IMHO, if you're satisfied with thr B60 at your target depths then:
Sell the GSD-24, keep the B60 (need 8pin plug for the 7612xsv) , buy a GT-50TM side/down vu (12 pin plug) which has a built in chirp element very similar to the B75M.
7612xsv has 2 xducer plugs: one 8 pin and one 12 pin.

B75 and B60 don't use the same size hole, B60 is 60mm (2 3/8"), B75 requires 70mm (2 3/4").

I can plug the B60 directly into the back of the 7612 (8 pin ) and add the new transducer into the 12 pin port. The B60 will hold bottom at speed and when I am looking for fish I will use the new transducer.

I just realized that I have the B164 transducer not the B60. The GSD24 is a 2000w rms sounder and I noticed that the 7612xsv is also a traditional 1000w unit. Is this a 1000W RMS output or are they playing marketing games using peak values? So I plan on removing the GSD24 and plug the B164 into the 7612xsv. With the GT51M-TM and the B164 I think this will cover all my bases for coastal as well as the deep waters 600' plus.

I could upgrade the B164 at a later date to the B175 which will drop into the same hole. Should I go with the low or high model when I upgrade if I do? Can I turn of the Traditional Chirp in the GT51M and use the B175 as my Traditional CHIRP or do I just leave it and have two CHIRP channels running one on the 8 pin port and one on the 12 pin port?

The GSD-24 is capable of firing 1000 or 2000 rms traditional watts correct.. it can handle a 2 kw R199 for example.

The 76XX series will fire 1 kw rms traditional wattage.

Your choice of bands for a B175 C depends on your fishing paramaters..depth ,coverage needed etc.

If you are using the GT51 it has a medium band element similar to the B75M.

You can just try the GT51M that to start and see if it gives you all you need..and then upgrade from the B164.
