Gotcha !! But, in that case ... NO, I don't know anyone that has two separate Livescope setups, though I believe there is a thread about that somewhere on here. I just can't remember where, or if it was a similar question to yours or not.

My concerns about two units on one boat :

Would the tdx pings cause interference if both units were running at the same time ?
Would two units at the bow be cumbersome (in the way) if two separate mounts have to be used ?
Would you have to have each setup connected to a separate battery ?
Would the layout of the boat allow two black boxes to be mounted out of the way, and still be easily checked on ?
