old reliable
porbeagle it is not loran c it is the unit. Micrologic is known for there inaccuracy along with at least 85% of lorans made. I have been installing Marine electronics for 20 yrs. and the only 2 machines that work 99.9% of the time are the northstar800 or 800x, and the furuno lc-90mrkII. I have owned both machines and the north star I will say is a bit better as far as speed and accuracy but the furuno gives you 5 lines of information where the northstar only gives you 2 lines.
Believe me I spent so much time, Filters Gnd. plates everything under the sun. with other units and after self experince and from other charter, party boat, and commercial fisher Capt's. these are the only 2 units 90% of them own and use. I love the 951 and the boat I Capt. now has the new 962 with the 10'lcd and course up which is unreal.
A good secrect with the Gps is when anchoring on a wreck I use only the machine to give me the lenght of line out and the bearing for postioning my anchors. i anchor sometimes 20 times a day on pieces and have found using the machine to be more reliable then loran and as accuate as a bouy. so don't drive your self carzy with fliters and gnd. plates it is your unit not Loran c.
Loran c has a repeatability of 50 ft. and is very consitent.
When I have used a poor unit as the micrologic what I do is get close to the number s and then make s turns along 1 line. 4300 or 2600. Then i'll use the gps to confirm my postion. I find this to be more helpful then using just the loran .being the gps track every 1 sec. and is acurate to within 3 ft.
