I recently bought a Garmin 12 inch plotter to replace the 7 inch Garmin. Stupidly I thought it would be a case of making the hole bigger, plug and play. But no. The 12 inch needs a separate antenna, and to get the sonar to work it would need a Garmin GSD22 black box to link the transducer to the plotter. The problem now is this box is obsolete! whilst searching the internet I came across a smartphone sonar that would link my existing transducer to my Samsung tablet by blue tooth! It looks like a good piece of kit and would fit the bill for my needs at a fraction of the price of Garmin kit (if I can even source it...) I rarely use the sonar function, but I wouldnt be without it. So the question is, has anyone any experience with Echo Zilla good or bad? really tempted to order one!!
