thru hull transducer or transom?

[BIGSHOW]

I have an hds-5 in dash and a thru hull ducer. The problem is I have a seperate temp probe(shoot thru hull) that quit working. I guess my option is to either put a new thru hull ducer with temp or remote temp (outside boat). Or install the transom ducer I got with the unit. Lowrance says they recommend thru hull and others say transom..Any suggestions?

I would think if you want accurate temp getting it thru the hull is not the best way.  I would leave the current 'ducer in place and add an external temp sensor if you can.

Cy's suggestion sounds like it would be cheaper too.   I like the idea of the hull protecting my transducer.  It scares me to have my SI 'ducer outside the boat, but that's the only way.

I did find a replacement temp probe (ep-35) to replace the other one. But reading some blogs I wonder if it just wasn't calibrated correctly through settings. I relplaced a 480m lowrance with the hds. Maybe i'll first hook it up and see what happens. It would always just read like 55 degrees.

I went to plug it all in and the power plug hooks up and the sonar hooks up and works but the temp probe wire comes to the dash and is on a splitter (network) with the gps puck. Then the plug comes out and won't plug in anywhere. It looks just like the 5 prong nema 2x plug on the hds but won't plug in. Any suggestions. I know i dont really need the gps puck but its on the splitter and i dont have any terminator plugs.

No way a inside hull glassed is going to work for Temp. Must be ext. mount or "Thru Hull" with probe in contact with the water. If cabled togather you may get a reading of trolling motot transducer. The best way I have found is Thru Hull mounted most time done when boat is being build which I did on last Ranger. It is awesome, not kick up's, no broke mounts and a justing. Now from Si and DI Big Bird from mounted to Fourtex with Transducer shield. It's a great set up an I do get very shallow. The factor mounts are Mickey Mouse use Transducer shield and save money of all ext mounts.

It is a thru hull temp. But it has its own wire and is networked in with the gps puck. It used to plug in my old lms-480m in the network plug. Now it doesn't plug into anywhere on the hds unit. I wrote lowrance an e-mail and they said I need an adapter.
