I have a 28 foot bertram fbc it has a old thru hull and fairing block for sonar i need to replace the old to new from boe .i have a hds 10 and want to add a thru hull side scan sonar with fairing block from boe so my? IS what thru hull sonar with new fairing block do i need to buy from u to go with the side scan sonarbfrome u i fish no more then 50 off shore of NC but mainly within 20 miles i need to no so i can order them from u ....thanks for your help...........

Ideally you will need a thruhull for each side of the boat to make side imaging work to both sides 100%. Since the ducers are pricey I'd suggest just getting one and getting 100% visibility to one side and maybe 60% to the other side. Here is the pair (are you sitting down?) - http://www.boemarine.com/LOWRANCE_DUAL_BRONZE_THRU_HULL_for_LSS-1-000-103650-01/

and the single ducer - http://www.boemarine.com/Products/000-10364-001/

As far as the main sonar ducer I'd suggest a thru-hull with fairing block on a boat like that, here you go - http://www.boemarine.com/AIRMAR_50-200KHZ_TH_Tri_AND_High_Perf_FB-GCO-B744V-BL/

I do not mind the the price for it to work rite i will be calling to order them next week ...thanks ...so now i think i need a e.net cable to and what will i hook all three ducers to ....also were do u suggest i put them under my boat thanks

Typically a ducer would go under the transmission on an inboard boat. This keeps it in front of the stuffing box.

Ya but if i use the two sidescan one port and one starbord of the keel under the trans how far can i put the true hull sounder from them and do i put it on the port or starbored side i wastold by a mec that the sounder needed tobe within 3 feet of the side scane sonar for my down scan to work rite ..?is can iput one ss sonar on each side close to keel amd then mount the other rite beside eather side scan thanks

Its not critical. I would pay more attention to mounting it in a good place so that it works. The only thing mounting them close affects is the overlay feature, and the deeper the water gets the less it matters. It won't matter on your boat. They'll all be close enough.
