I have the 997 CSI with canonlink and a digitrol 5 and love it. I have not purchased a second digitrol so have a tournament series non digitrol DR as my other unit. Comparing the use of both the canonlink feature is highly preferred. I am about to purchase a second unit when the Helix 10 G2N is available in my region in Canada and will have to keep my 997 in order to use the canonlink. I'm just not sure at this point how the installation will go as I will of course want the new Transducer and would be nice to network if possible,
Its unfortunate they didn't keep the add on software for canonlink for the new units.
Someone at Cabelas told me the reason they did not continue with canonlink was simply due to lack of demand, however I find that hard to swallow as its so much more advanced in convenience and status.
