It looks suspiciously like a decimal point is moved for some reason. I am not a Dr. but I'd wonder if 161/109 were valid reading (not one that you want, I'm only guessing at the concidence.

Hi Maryann. I'm not sure what the difference is; maybe you can Goggle them and compare. Sorry. :-(

i believe M Dabal had the best answer. they are different and used for different things. they are not interchangable.

I don't believe there is a difference (at least not that I know of ). I think it is just a mistake of some sort on the size indication bar. Sorry if this didn't help.

They are pretty much the same. Just make sure that you do get the adjustable declination or variation. The dial is luminous which is handy. I think the M-3D refers do the adjustable declination. It is pretty tough as I keep it in my PFD on the water sea kayaking.

I can't give an answer. When I put in 3 it did not work and when I put in 9 it did not work.

I don't know what the difference is between the two numbers. Have you tried to "Google" it using each number? Wish that I could be more helpful.

It's mil, not mm. Easy mistake to make. A mil is 1/1000th of an inch. 50 mil is 1/20th of an inch.

Hey Bill. I don't know for sure. but I guess the one is slightly bigger. I asked google quickly and it says that MD also stands for medium making no difference on that aspect. I do have to say though: the fins aren't nearly as stiff as i was hoping and provide very little power.they did however work well for me after breaking my ankle because they put less stress on my sensitive joint. this is definitely not a bodyboarding fin but will be fine for snorkeling or for a bit of extra power for body surfing. Enjoy shopping.Ieuan

I just checked mine. Let me make sure I understand your question - I entered a number into memory, hit AC (all clear), closed the lid, snapped it shut. When I reopened it, the M symbol still showed in the upper left hand, and the MR restored the number I put into memory. It didn't "dump" that stored number until I hit the MC button. Hope this helps! ~Laura

There is no difference. It's just how they list it. I ordered a 12x short and it's just a 12 short.

I believe they are the same. People are often just too lazy to type or say "inch" at the end. BTW, you will notice there is also a numbers system, which I believe is simplification without typing 4 x/8 inches so it became just x. It starts at number 0 for 4 inches even, and increment a count for every 1/8 of an inch. So 4 1/4 inches is also number 2 as it equal to 4 2/8 inches. Number 4 will be for 4 4/8 or 4 1/2, etc.

Hi Devon, so what conclusion do you have. I am with the same problem. Is 827 3 times bigger than 809 and the 819 2 times bigger than 809? Thanks for any help

Did you ever get an answer? I got both for Christmas and I don't know what the difference(s) is/are.
