Default Which Thru Hull Transducer do I need?

Hi,

I need some expert opinions on which transducer my application requires. I currently have a thru hull transducer that I need to replace as I've updated the unit now requiring a 50/200 instead of the 192. My current unit is also 2 feet below the water surface in the back 1/3 of the boats hull next to the engine as it is an inboard. This area of the hull is should always remain in the water. It will be mounted thru a 25 degree deadrise hull. My boat runs tops around 40mph.

I would like to get accurate sonar information and temp readings while running. The head unit is a Garmin 2006C along with the Garmin GDL 21 sonar unit.

My question is which type of unit to use. In my shopping I've found some that indicate 12 degree and various other degree angles. I've also been asked if I need to have a faring block. What do I really need to have???

Thanks,

Jim

Consider Airmar's thru hull tilted xducer for a nice smooth/flush install (no fairing required).
Had this baby been available when i bought my ray c80 i would have chosen this over my bv744 xducer with fairing.
not sure of the tilted xducer's part#, but do a seach in BOE's website under "tilted transducer" and it will pop up.

A Airmar B60-20 will work well with that unit. This is the famous Airmar tilted element transducer in 20deg. It will work fine on the 23deg hull. No fairing block involved. It stick's out of the hull 3/16in. 600watt unit.
It will need a 2 3/8in hole.

Since no one asked, I will, what type of depths do you normally fish in?

Hi All,

I will normally be using it up to 1500 feet. Thanks for the advice.

If you are serious about going above 1,000 feet, you would want one of the AirMar 1kw transducers, even though the GSD21 would only push it at 500 watts simply to get the greater sensitivity of the multi element array inside. If you don't necessarily worry about what is in the 1,000-1,500 foot range often, I'd go for the tilted angle Airmar B60 mentioned above, there will just be times (mostly dependent on water conditions you can't control) when it won't go down much past 1,000 to 1,500 feet, even with all the manual tuning in the world.

The hardest thing to replace in any FF unit is the thru hull transducer. if you plan of keeping your boat i'd replace it with the lastest and greatest transducer out there, an Airmar B260. Their prices are falling to around $5-600. That way if you change FFs in the future you will only need a transducer pin-out change or adapter if at all. Wish I'd had followed my advice. I have the Airmar BL-244V, mid-quality and price ($236) which is good but does not have the high detail as the B260. I have a 7" 600 rms Lowrance LMS-337C but the 1K 10" LXC-111CHD are being discounted now and are quite affordable. So if I had it to do over I'd have bought the B260 to endstate my transducer.
