[CA] [CA11] Element transducer choices, wooden boats

NLNATL,

Q1. If I put it on a switch on it to turn it off, is there any reason the HV-300 will be affected by the dormant unit (magnets?) if placed 18 or 20 inches away?
A1. Not likely. The solution of switching which sounder will be used would indeed be an acceptable approach to avoid any adverse sonar effects to either system. Please note that Element's ping may be disabled via the Fishfinder settings menu.

Q2. How close to the wooden keel can the transducers be placed without interfering with the downward cone angle?
A2. It would typically be recommended that the transducer be located no closer than 12" to the keel and that it not be located in direct line with a prop (outside of the swing of the prop) to avoid aeration of the prop of planing hulls. The low power/high frequency CHIRP conical sonar characteristics of the HV transducers is very similar to that found within RealVision, DownVision, and CPT-S transducers (i.e. 25 degree cone angle), albeit transmitting at 1/2 of the wattage (100W vs 200W).
