Ice Sonar
Scanner that makes sure the ice (or snow) in your path will bear your weight | |
I am always very nervous when I venture out on frozen lakes to go skating or skiing that the ice will not be able to take my weight, and I will go plummeting into the icy depths. (This is partly because I live in the city and don't get to do it very much, I suppose.)
Also, I have read that hidden
crevasses are a major danger to Artic and Alpine workers, whether on foot, ski or snowmobile.
So how about a handy little sonar (or radar), that will map out the ice depth or the under-snow conditions ahead of you, with a convenient heads-up display? (On a snowmobile, it could be mounted on the dash.)

...but, wouldn't you guess it, it's for (ice) fishing, not safer navigation. [DrCurry, Mar 07 2006]

I don't know if SONAR will work but ground penetrating RADAR exists. Don't know if a handheld device is practical, though. Pretty high radiation danger and maybe a large power requirement? |

Most snowmobile deaths in this country occur with an inebriated male speeding across a nearly frozen lake at night. |
|
| |
Who is this inebriated male? Someone should stop him! |
|
| |
Oh, now I understand. But why aren't females killed the same way? Is it because the females are...
...lighter weight?
...less likely to be inebriated?
...not allowed on snowmobiles?
...luring inebriated males to their deaths by scampering around in only seven layers of clothing (practically naked!) on the opposite side of the lake? |
|
| |
Fewest snowmobile deaths in this country occur with a sober female slowly traversing snow in the daytime. |
|
| |
You'd think she'd make an easier target. |

applause, beaux, for the whole series. |
