When I update my card and get a new one I’ll get the Smartstrike version. My local lake, Conroe, has been updated since I purchased my Hummingbird card but I have not bought a new one yet. I bought my current card about a year before it was updated. I did buy Smartstrike separately and added it for Conroe and I believe Rayburn.
So, if I needed a new card or wanted an updated one I’d get the Smartstrike version or if I had a new card already I’d just get the Smartstrike. I can’t say it has helped me catch more fish but it’s nice to look at the recommendations.
