This may be overkill but I had a Garmin Striker 4 that I use to use and this year purchased a Garmin Striker 7 Vivid which I installed but have not had a chance to use due to health reasons. So my question is I have the mount on the rear of the boat where I sit but was wondering can I install the 4 on the front of the boat so my buddy, when fishing with me can use that at the same time I am using the 7. Im not interested in connecting them together, just separate. I didn't know if they would interfere with the reading of each other. The boats they are used on are a 14 ft jon and a 10 ft plastic pontoon type boat. Thanks for any advice.
