Default Garmin Echomap 54dv - Conventional vs. Chirp

I am thinking of purchasing the new Garmin Echomap Chirp 54dv system and I have been told by a Garmin rep that I wouldn't notice any difference between the conventional dual frequency Downvu and the new Chirp Downvu unless I ventured into waters deeper than 250 feet. I will be fishing the Chesapeake Bay and won't see any waters that deep. My impression was that the Chirp technology would make that system more clear and better detailed in any depth. Is this true, or will I not notice a difference in shallower waters?

Many comparisons have been posted recently you are spot on with your impression. It really depends on what you want and what you want to pay. Personally, I'm holding out for the new CHIRP systems but that may not be my rational side talking.

The low Q-factor of a CHIRP transducer will give much better resolution also in shallow water. This is valid both for fixed frequencies and CHIRP mode with such a transducer. In shallow waters it's the transducer and not necessary CHIRP mode which is making the difference between a conventional and a CHIRP capable system.

You will certainly see greater detail with CHIRP processing in both CHIRP traditional and CHIRP Down Scan ..but the transdcuer choice is also important.
A low Q transducer will always give better overall performance vs a higher Q unit.

And besides the CHIRP Down scan of the new 54dv you also have traditional in CHIRP.




On the left is a traditional element like you will find in a non CHIRP 54dv..on the right the CHIRP element similar to the CHIRP echoMAP 54dv.


Both CHIRP and non CHIRP will put one on the fish....it may just come down to ones budget.
