TRINITY'S 1st Annual 2010/2011 Icing/ Anchoring Challenge

[DetectorGuy]

... good times!...
I can't speak for team Gilligan on the numbers of holes cut, but Team Isanti only cut 15 holes all season. Between the two of us we pulled 90 anchors out of those 15 holes. I think our [glow=red,2,300]MASTER DIVE PLAN[/glow] had 51 pages and we only used 15 of them. We went with one hole per day except for one day we cut two holes. Most days we did two long dives each... none of this mamby pamby 15-20 minute stuff for us. The average dive time for my 24 ice dives was 46.25 minutes per dive.  Nates average dive time for his 21 ice dives was 47.9 minutes per dive. My longest ice dive was 81 minutes and Nates longest ice dive was 91 minutes. Like I said before when I was hinting to what made us successful... The anchors are on the bottom and the more time you spend on the bottom looking, the more you will find.  8) There has been a bit of amazement as to the reasons why we hit Green Lake so much. Green Lake used to have the most anchors per acre, and had the State record for the most anchors coming out of one hole... 3 different times. 18 anchors from one hole, 19 anchors from one hole, and then 20 anchors from one hole! I am proud to be a part of those three times. Here is a quote from me in the thread that talks about the search patterns we used primarily:

"First diver would cover from 25' to 100' radius
Radius         Diameter          Circumference
25'              50'                  157'
37.5'           75'                  236'
50'              100'                314'
62.5'           125'                 393'
75'              150'                471'
87.5'           175'                 550'
100'            200'                 628'

Second diver would cover from 112.5' to 150' radius
112.5'          225'                 706'
125'             250'                 785'
137.5'          275'                 864'
150'             300'                 943'

So here are the fun numbers:
For each hole (between the two of us) we efficiently searched 70,686 square feet (or 1.62 acres). While searching each hole (between the two of us) we swam 6,355 lineal feet (or 1.2 miles).

Over the 2010/2011 ice diving season (between the two of us) we efficiently searched 1,696,464 square feet (that is one million, six hundred and ninety six thousand, four hundred and sixty four square feet for those that are challenged when it comes to numbers) or as us farm folk like to say 38.94 acres. While searching for those elusive anchors (between the two of us) we swam 152,520 lineal feet (or 28.88 miles)"
We took a bit of heat after we put this info out there the first time with people thinking we were too detail oriented by making our radius changes in 12.5' increments. The logic was simple as we have our primary and secondary dive ropes marked out in 25' intervals. 12.5' is 1/2 of a 25' interval so if a diver wanted some slack to reach something we would give the slack and then return the diver on the exact intended radius. My wing span is exactly 6 feet so I could find a 25' marker on the dive rope and quickly "measure out" 12.5'. The other reason this radius interval worked so well is that the viz was commonly about 8' so we would have just a bit of overlap in the range of visibility frome one radius to another.
