I felt like my build was less “ala carte” and more “all you can spend”! crimminy these things are as bad as spec’ing a truck or euro car - base price is HALF of what you pay after options!
Seriously though, while that Striker is better than nothing you may find yourself wanting more later on depending on what your needs are. Just having a true navigational chart is worth the price of an upgrade, depending on what water you’re on. Small lake - you’re good to go. Larger lakes and other bodies of water with shoals, spoils, mud flats etc. and you’ll want to upgrade - run aground once and it will have paid for itself. Sometimes those marker bouys float away so having an additional aid will keep you and your family/guests as safe as possible.
