I've used a Striker 4 Ice Fishing Bundle for 5 or 6 years now. Also use it in my boat hooked up to my Minn Kota PowerDrive US2.
A great inexpensive unit but I haven't fully explored it's capabilities.
I found YouTube tutorial videos by Paul from 1Cast 1Fish explaining the unit. Very good videos that are easy to understand, short and to the point.
If picked up all kinds of useful info from the series. I think it's also useful for the full Striker lineup.
If you have a Striker you may find these videos helpful.
