I needs some advice....

I'm looking to purchase a thru hull chirp transducer for my 21' BW Outrange and I'm looking for advice on what to get. I've narrowed it down to an Airmar B75M or B75H. My question is if I should go for the low or the high. I talked with Airmar and they said go with medium, but it seems like most people in So Cal go with high.

I'll use the boat same as most people on BD. 100% saltwater fishing inshore, offshore, islands, etc. The until will be connected to a new Garmin 742XS. I also have a Furuno 585L with an Airmar P66.

The reason I'm set on a thru hull is because I am relocation my bait tank pickup to a deeper spot and I figured I'd put a transducer there since there is already a hole. This will be my one and only chrip transducer (not looking to add a second).

I appreciate any advice you have!

I would do the medium.Actually I did.My other ducer is a 50-200 so I went with the med.Just me,I dont think the chirp was worth the money.My goto is the 50 for 99% of my fishing.Tom

If your 585L supports 1kw, I suggest you replace that P66 with a TM260. The returns will amaze you.
I run mine in 50hz most of the time due to its wider cone.
I use traditional over Axiom high Chirp most of the time.
This picture shows both 50k and high Chirp side by side.

This is 50khz in shallow water.
