ice diving I maintain contact with the surface by use of a rope a surface

surface by use of a rope a surface

surface by use of a rope a surface support personnel a tender is assigned

support personnel a tender is assigned

support personnel a tender is assigned to every diver and we use a rope to

to every diver and we use a rope to

to every diver and we use a rope to communicate and know a way out now the

communicate and know a way out now the

communicate and know a way out now the rope the tender one thing that my tender

rope the tender one thing that my tender

rope the tender one thing that my tender learns is how to keep tension on the

learns is how to keep tension on the

learns is how to keep tension on the rope so we can use this and not get

rope so we can use this and not get

rope so we can use this and not get entangled and this is also used as a

entangled and this is also used as a

entangled and this is also used as a communication tool

communication tool

communication tool my tender can give one pull on the rope

my tender can give one pull on the rope

my tender can give one pull on the rope which is asking if I’m okay and I don’t

which is asking if I’m okay and I don’t

which is asking if I’m okay and I don’t want to make sure I want to make sure

want to make sure I want to make sure

want to make sure I want to make sure that I’m not going to confuse signals I

that I’m not going to confuse signals I

that I’m not going to confuse signals I give one pull back after a little delay

give one pull back after a little delay

give one pull back after a little delay and then my tender takes the slack back

and then my tender takes the slack back

and then my tender takes the slack back up and the tender will give me two pulls

up and the tender will give me two pulls

up and the tender will give me two pulls on the rope that’s telling me I’m as far

on the rope that’s telling me I’m as far

on the rope that’s telling me I’m as far away from the hole as she has roped so I

away from the hole as she has roped so I

away from the hole as she has roped so I acknowledge back one pole that I need to

acknowledge back one pole that I need to

acknowledge back one pole that I need to change directions I can’t go this way

change directions I can’t go this way

change directions I can’t go this way anymore I need to start going this way

anymore I need to start going this way

anymore I need to start going this way to continue on my dive

to continue on my dive

to continue on my dive that there’s a few other signals but one

that there’s a few other signals but one

that there’s a few other signals but one that’s very important I’ll come back to

that’s very important I’ll come back to

that’s very important I’ll come back to is things could go wrong and I may need

is things could go wrong and I may need

is things could go wrong and I may need to get out of here so if I give three

to get out of here so if I give three

to get out of here so if I give three poles to my tender one two three I’m

poles to my tender one two three I’m

poles to my tender one two three I’m saying I want to get out of here

saying I want to get out of here

saying I want to get out of here and if I really want to get out of here

and if I really want to get out of here

and if I really want to get out of here I’m going to keep pulling to make sure

I’m going to keep pulling to make sure

I’m going to keep pulling to make sure that she got the message and she would

that she got the message and she would

that she got the message and she would start pulling me back to the exit

start pulling me back to the exit

start pulling me back to the exit now I also use wireless communications

now I also use wireless communications

now I also use wireless communications so a lot of times when I’m diving under

so a lot of times when I’m diving under

so a lot of times when I’m diving under the ice I can talk directly to another

the ice I can talk directly to another

the ice I can talk directly to another surface support personnel or my tender

ice diving is a team event it takes

ice diving is a team event it takes several people to pull off doing a nice

several people to pull off doing a nice

several people to pull off doing a nice dive but for each diver it’s an

dive but for each diver it’s an

dive but for each diver it’s an individual experience now once I’m at

individual experience now once I’m at

individual experience now once I’m at the bottom of the lake there’s really no

the bottom of the lake there’s really no

difference to diving in the summer well except for the rope and I can only get

except for the rope and I can only get

except for the rope and I can only get so far away from the hole but being at

so far away from the hole but being at

so far away from the hole but being at the bottom there’s really no difference
