I am currently upgrading my front hummingbird unit to a bigger screen DI unit. I decided not to go with side imaging on the front because I have it on my smaller unit on the transom and dash. How many of you feel side imaging is necessary
for the bow. Is it worth the cost difference if SI is already on the boat? I cannot link my two units together until I upgrade the back unit and I am unsure if I upgrade will my way points set from side imaging show on my front unit. Any way what I am trying to decide is do I go ahead and upgrade the front with SI now or wait till I upgrade my back unit and link them thru intanet? Your thoughts would be appreciated.
