ive been thinking of upgrading my dated electronics. I currently have a c80 classic/dsm250/tm260 at the helm and an older garmin sounder for the back deck. My hope would be to get a 7-9” back screen integrated with a 12” front screen and be able to use the tm 260 50/200 transducer along with the included chirp transducer with the system. The thought is to buy the back screen first and buy the front screen and radar later, i dont want to get screwed buying a cheaper chirp back screen that i find later wont integrate with anything (i had looked at the simrad go7 xse). To accomplish this i am looking at either the raymarine es series or the simrad nss evo 2/3. I am not a huge fan of the garmins and furuno is out of the price range. It appears that simrad will run chirp and a 1kw 50/200 without an external sounder module and raymarine will not.... anyone with experience on this? The reasoning behind this is that i just upgraded my main ducer after the old one got ripped off the boat the last time out, the 1kw tm260 beast renders the old garmin gpsmap498 useless as it has so much crosstalk, chirp should fix this it seams. I am also assuming the boat show will be the best pricing..... i have been eyeballing the reman nss units because of price.
