cbondy Posted May 31, 2020 Report Share Posted May 31, 2020 Looking to add a Ritchie compass to my 2013 Pathfinder 2400 TRS. Ritchie offers a couple of models designed for dash mounting requiring either a 2" or 3" hole. I am leaning toward the larger, 3" model and position it as shown in the attached pic between my Lowrance GPS and Sonic Hub. My question is the larger compass just too big for this position and possibly make the dash too weak structurally? Better off going with the smaller, less capable (no compensation feature) compass? Maybe a different position? Appreciate any advice from more experienced riggers. Quote Link to comment Share on other sites More sharing options...
HoneyB Posted May 31, 2020 Report Share Posted May 31, 2020 I would say one inch of glass Around the hole would be fine. That glass is only there to hold “stuff” for your viewing pleasure. A nice hole cut with a nice tool such as hole saw or rotozip would be fine. Just my 2€. 1 Quote Link to comment Share on other sites More sharing options...
jh141 Posted May 31, 2020 Report Share Posted May 31, 2020 I agree, I have a 16" Carbon in the center of my the dash, it has not caused me any problems nor does it concern me. I would go with a compass that has the compensation feature for sure. JIMO Quote Link to comment Share on other sites More sharing options...
bernieNC Posted May 31, 2020 Report Share Posted May 31, 2020 My question is what, if anything, does Lowrance say about mounting so close to a compass??? Quote Link to comment Share on other sites More sharing options...
Bamaskeet Posted June 1, 2020 Report Share Posted June 1, 2020 I suggest you remove that ugly cup holder on top of the console and flush mount a flat card, Powerdamp Ritchie compass. 1 Quote Link to comment Share on other sites More sharing options...
fin-addict Posted June 1, 2020 Report Share Posted June 1, 2020 This is where my compass is located, not a problem with correct readings until about a year ago. Old, needs replacing but not doing so. Do not use it. Picture shows reading is off from what the gps shows for those with zoom or eagle eyes. Think the cup holder is just fine where it is. Serves a purpose. Question, has the hole already been cut. It appears so but might be wrong. Why the need for a compass, you have the gps. As a backup you can use your cell phone or have a hand held marine type as a back up. With a regular compass like the one you want there are factors to consider when using it. Wind, current, deviation and speed your going. Will not work correctly if these factors are not put into place. JMO. 😀⚓️🙏 fin Have the same ugly cup holder on my console. Can see part of it in photo. lol Quote Link to comment Share on other sites More sharing options...
Bamaskeet Posted June 1, 2020 Report Share Posted June 1, 2020 A couple of years ago, I was 31 miles offshore and my GPS had a electrical problem and shutdown. Getting home wasn’t a problem because I had my flat card compass mounted on the center line of my console. I also use my compass, in conjunction with my mapping program, in the fog.

cbondy Posted June 4, 2020 Author Report Share Posted June 4, 2020 Thanks to all that provided feedback on my question. Much appreciated. I also contacted my dealer, Mt. Houston Marine for input. The fiberglass on that Pathfinder dash is about 1/2" thick and pretty bullet proof. Also got a bit of information from the compass manufacturer, Ritchie. They advised the audio system speaker magnets will interfere with the compass heading if too close (w/in 18"). Not a problem here since they are mounted low on the console sides. Attached is the installed compass. Plan to try it out this weekend on a trip to Galveston West Bay. Thanks again! 1 Quote Link to comment Share on other sites More sharing options...

bernieNC Posted June 4, 2020 Report Share Posted June 4, 2020 Looks good. FYI...I like the cup holder. Quote Link to comment Share on other sites More sharing options...
smilemaker Posted June 4, 2020 Report Share Posted June 4, 2020 A neet trick when dealing with compass and magnetic interference is to use the compass on a phone app.Open up the app and as you walk around with it you will see the needle swing and the app warn you of the interference. You keep moving around until you find a spot with the least interference. Quote Link to comment Share on other sites More sharing options...
