HDI skimmer transducer 83/200 & 455/800 for all Elite-7 models including Touch ($109) and the matching trolling motor adapter/shield for it($20). Prices were what I paid at BBG. I got the LSS-2 and just didn't return these in time to get a refund. Very little use and in the original boxes with paperwork. $100tyd. Save yourself $30 plus tax and shipping. PM me if interested. Don't know if they would work with anything else, but you could check with Brian at BBG.
