[CA] [CA11] Upgrading Axiom sonar capabilities

[a7ewizard]

Chuck,
I am pretty sure on my upgrade. My main goals are to differentiate bottom structure, mark bottom out to 1500 feet, show thermoclines and to meter fish and bait suspended to 300 feet.

Realistically, the vast majority of my fishing will be in water less than 150 feet. The upgrade is to try for swordfish, albacore tuna and deep bottom fish when offshore conditions permit. Consequently, I think a non-chirp option will be the most cost effective for me.

At this point, I'm pretty much set on a CP370 sonar module with a 1kw transom mount TM-258 50k/200w transducer. If Airmar's specifications are accurate (best case scenarios), this combination will satisfy my goals as stated above AND I will retain Axiom RV's high frequency chirp capability.

I think the transom mounted transducer will perform extremely well at drift and slow troll. I'll just have to wait and see how it does at cruise speed. Give me a few months. I'll be back with my observations.

Thanks again.
