The total time for making the installation will depend on the boat size and type and which system you buy. The installation simply requires the fitting of one or more transducer mounting rings to the inside of the hull by means of epoxy resin and a control box screwed to an adjacent bulkhead. In real terms this should take no longer than 3 – 4 hours for the Ultra 10 system and up to 6 hours for the Ultra 20 system depending on the boats layout and cable run.  We do recommend once the transducer rings have been fitted you leave them to cure for approximately 24 hours until completely dry for best bonding effect.
