Looking to add a cheaper fish finder for my kayak.  Curious as to whether anyone has an opinion on the Garmin Striker 4 vs the Garmin Striker 4cv.  Is the CV really worth it?  Considered buying the portable striker4 because I also ice fish in the winter.  I wondered though if the transducer for the portable unit is compatible for moving from my kayak and then out onto the ice? Portable one also comes with a battery ready to go.  May sound like dumb questions but I am new to working with fish finders.

This topic is relevant to my interests.

 

I am looking at buying one of these two models and comparing them the difference is the cv model supports 260/455/800 kilohertz frequency, has 100 watts additional power, draws 170mA more current and includes a different transducer.

 

I have never used or owned a fish finder and would be interested in responses of if the higher frequency makes any tangible difference.

It looks like the advantage to the higher frequency is a clearer view of what the radar 'sees', but the radar cone is more narrow looking at less of a radius.

Does the higher resolution really matter?
