Well actually I have a underwater camera battery already n soft water version elite 4 hdi lowrance so I just went thru navionics.com lowrance accessories n parts site n bought an ice ducer 69.99 and then bought a softside/ hard bottom portable bag at 19.99 cabelas it has ample space but no base for unit to attach too but I planned to add terminal connection for original battery wire and measure a base to sit mounting bracket too but if I had to do again I'd just buy the lowrance portable ice kit the elevated base is worth it it fits the bag better cabelas sells battery 29.99 ea. So u add up bag ,ducer, and Battery 110.$ n lowrance has kit for 100-120 I believe if your just looking for ice ducer look at your color code plug it should be blue if it is the site I named has em part pti-wbl the other model is a red boot plug ring hope this helps they have it too
