I agree with the post on the M9. I bought one and I was disappointed with it. M9 is not made for catsailors, it might work better for monoslug tacticians.

The GPS take forever to acquire, it loses the signal easily and the battery life is poor. The magnetic compass works well and I am going to keep it as a back up GPS in case of an emergency and as a backup compass on longer trips. The other issue I have is the computer interface is next to impossible to figure out, the manual on this is poor and the maps are very hard to find and expensive. Dont bother with the M9, unless of course you want to buy mine for full retail.

I am interested in what people think of the Timex version with the detached gps receiver.

I went through 3 etrex, they are not waterproof, I think what happens to them is that the salt water crosses the connections and the unit shorts out, but thats just a guess.
