I have been running Garmin for a lot of years. I use the 93sv echomap series on the console and decided when the striker unit came out, I would save some money and put one of them up front. After trying the striker, it wasn't hard to see the striker series was not even close to the echomap when it came to clarity and images. I talked to a Garmin rep just a couple days ago about their transducers. I found out the CV series transducers do not have a dedicated crystal in them but gets the image feed from the unit itself. Even the new touchscreen series echomap plus units came out with the CV series transducers. They are Livescope compatible but the CV series transducer is 2nd generation. The latest transducer they produced is the GT 22 and the GT 52 series. They do have a dedicated crystal built into the transducer and it's a lot clearer on down imaging and side imaging. If you have a current Garmin 93sv with a 12 pin connector or a 73 with an 8 pin connector, you can upgrade the transducer to a GT series. The GT 22 is for a 7 inch and the GT 52 is for the 9 inch. I did not ask if they would work with the striker series. The GT 22 series transducer sells for 189.00 and the GT 52 is 300.00. Don't think most people would ever notice the difference in the CV and GT transducers except the die hards like myself.
