Hello everybody, a newbie here.
I purchased today at a garage sale a brand new in the box Matrix 35 fishing system with transducer, speed pickup, GPS ready, all cables and mounts for $50. I believe it was a good deal.
I looked all over the web today for the GR4 GPS puck to no avail. Not made anymore.
My question: what/will work with this unit. I have seen GR16 and lots of AS GRP GPS receivers but can't seem to find definitive answers to whether or not they will plug and play on the Matrix 35. Any help would be appreciated.
Thanks
