Get a network cable and they will both run off the same puck. They make them anywhere from 2 ft to 20 ft long. The cord will attach right to the back of each unit and then you can tell the second unit to use the gps from the first unit. You can also share transducers then as well. Bonus!!
Now I’m confused. Is it a network cord or a ethernet cord or are they the same.. Really not tech. savy.. There are 2 ends on the original puck unit. One goes to the 1st 858 and can i just hook the other one up on the accessory side plug? Sorry but looking for a little more detail. Trying to save a little money and install on my own..May regret it but going okay to this point.
Thanks Roger and IDO… Been surfing the site for years and finally got registered… Nice to have a group of people to fall back on with outdoor/electronic/hunting/fishing questions. Thanks again…………
