Funny as I re-read andym's post I see now that it was a joke, I figured he knew better. Guess I'm a little sleep deprived from my last fire and didn't catch it. |

And it takes care of worrying about whether it is level. |

andym: "Yes, it was a joke. This forum doesn't have a tradition of using smiley faces and so it is hard to make that clear.sorry Andy, I couldn't see your tongue in your cheek. And I am the guy who warned my kids over and over about all the reasons texting is bad!! Classic example. |

Another idea would be to use the 3m command strips. Those hold well, come off easily, and aren’t supposed to leave a residue. |

BobDobbs: "Does anyone have a solution for temporarily mounting a compass on the bow of a rented tandem canoe? " I had this same problem to address during a trip over the summer. I ended up using two rubber bands to attach an entry-level orienteering compass to the thwart in front of the stern seat. I imagine you could do the same thing to the bow carry handle. It quickly came on and off for portaging and I could stick the compass in my pocket during the portage or into the pocket of my thwart bag. Note that this method is good for general direction finding, I would say within 5 +/- degrees given how far your head is from the compass when sitting in the canoe and how exactly level you can mount the compass. Any more accuracy than that should be either unnecessary with good location awareness or remedied with map and compass skills. |

you could attach a compass to a bow bag tyh |

On the ten day solo this July I never took the compass out of the day pack. |

Kinda like the broken clock being right twice a day. |

Am I understanding correctly that you're suggesting putting two ferrous pieces of metal in contact with or close to your compass? Isn't this going to mess with the magnetic accuracy of the compass needle? -Confused in Illinois |

It was intended to reflect that I got the joke in an ironic way rather than a "HAHAHA" way. Because I took it as more "sarcastic" or "ironic" humor than comic, belly laugh humor. However to some, it turns out, it was not humor at all. Shame on you andym! Be funnier in the future. |

I purchased a canoe that had Velcro wrapped around a thwart... The former owner had a piece of Velcro on the compass. I'm lazy... I have a strap on my compass that I wrap around a thwart and just lay on a pack ( I'm in the stern here though...) I used to have a compass without a strap and it encountered that " slow sinking feeling' described in another thread. dr bob |

LOL thanks, but not interested in circumnavigating the globe. |

andym: "...very consistent readings." True. |

Yes, both the metal plate and the magnet will screw up the compass. I was counting on the magnet so completely screwing up the readings by locking the needle that no one would get lost due to my suggestion. FYI, my wife's master's thesis was on magnetism recorded in the rocks of the Sierra. So we know something about magnetism around this place. Also FYI, she thinks it was a really dumb joke. |

Maybe I’ll have to see if BeaV will bite. |

OCDave: "DrBobDg: "doesn't the magnet mess with your readings? Just the ferrous metal plate I suggested gluing to the compass will screw with the readings. Geologists traditionally use brass belt buckles to avoid this problem. The magnet just makes it obvious the readings are nonsense. With either a strap or the hose clamp, you can easily level the compass fore and aft, but side to side will rely on shifting the boat (unless you can slide it on a curved thwart). There are marine deck mount compasses that are designed to compensate for tilt of the boat. You might be able to rig one up with straps or (preferably plastic) wire ties. |

Not only will a magnet affect your compass's direction, one that close will most likely freeze the needle so it will not move at all. I just tried it and it froze up my Sunto Compass, here are the pics. My cell phone also affected my compass's direction as well as anything steel that I put near it. Link |
