[jimmy's marine service]

well... i've ran into a few raymarine problems,all due to installation...it's real important these units have a good power as well as ground source...i reccomend a dedicated buss for both the ground and the power...it's an excellent idea to install a seperated and dedicated power system in the boat,that meaning,the engine batterieis fire just the engines and the 12v system battery fires just the 12v system...this avoids a low voltage situation...all this little stuff matters...if you're feeding the electronics through a common power wire,meaning,it's power is coming off a buss bar,that feeds other circuits,the wire that buss bar may not be flowing enough power to keep everything going,it's kinda like a garden hose supplying water to your house...the same is true for the ground....you may wanna check into all this....
for what it's worth,the raymarine c as well as the e series sets are my choice,hands down the best,in my opinion...the c series with the dsm,gives the absolute best definition screen for a fish finder i have ever seen...
